Isran Ramli and Muralia Hustim Abstract-- This paper attempts to understand influences of the flood puddle disaster on the durability of an asphaltic mixture which utilize marble waste as a filler material. We have carried out an experimental research using a modified immersion test in order to grasp the effects of the phenomenon. The experimental laboratory testing treated the immersion test for duration 1, 4, 7, and 14 days on the three asphaltic concrete mixture types. The three mixtures based on the various marble waste contents as a substituted filler material such 100%, 50% and 0%. This study analyze three types of durability indexes in describing the asphalt mixtures durability, i.e. the retaining strength index (RSI), the first durability index (FDI), and the second durability index (SDI). The results show that the flood puddle phenomenon smoothly affects the deterioration of the mixtures durability. However, the mixtures containing the marble waste still survive in the strength limit until fourteen days immersion. These results seem a promising in utilizing the marble waste as the substituted filler material on the asphaltic concrete mixtures.

INTRODUCTION Nowadays flood as one disaster as an impact of global warming and climate change has been deteriorating environmental qualities of urban infrastructure in tropical countries. In particular, the disaster provides a puddle phenomenon as the continuing waste to a road pavement infrastructure [1]. In the previous research [1], we have described that the phenomenon Ali, N., is Associate Professor of Civil Engineering Department, Faculty of Engineering, Hasanudddin University, Perintis Kemerdekaan Km.10, Makassar, 90145, Indonesia nuralimti@gmail.com Ramli, M. I., is Associate Professor of Civil Engineering Department, Faculty of Engineering, Hasanudddin University, Perintis Kemerdekaan Km.10, Makassar, 90145, Indonesia muhisran@yahoo.com Hustim, M., is Assistant Professor of Civil Engineering Department, Faculty of Engineering, Hasanudddin University, Perintis Kemerdekaan Km.10, Makassar, 90145, Indonesia muraliahustim@yahoo.com leads to deterioration on durability of the pavement surface layer or asphaltic concrete mixture. The water infiltration into the asphalt pavement is a primary reason for this deterioration. The most serious consequence of the adverse action of water is the loss of adhesion between the aggregate and bitumen, such stripping, resulting in a substantial reduction, in the strength of the bituminous mixture [2]. However, only a few scholars have conducted researches on the field of the adverse action of water. In this regard, Siswosoebrotho et al. [2] developed a cyclic water vapor test for durability assessment of bituminous mixtures of asphalt pavement material. Their research focused on a cyclic water vapor effect on asphalt concrete mixtures. Further, Ramli et al. [3] researched the phenomenon by using the cyclic vapor test to asphalt mixture that focused on Butonic Mastic Asphalt (BMA) mixture. These researches have focused only for effects of a cyclic water vapor, a condensation process, i.e. a process of evaporation of water from the subgrade up to the subbase and base layers during the day followed by condensation when the temperature decreases in the night. Normally, the process occurred in the area of high ground water level, poor subbase, and base layers that contain many fine-grained materials, and happened cyclically for a long time and may damage the pavement material from the bottom of its layer [2]. Those researches do not describe the effect of water infiltration to the asphalt pavement, moreover to represent the impact of the flood puddle phenomenon to the asphalt pavement durability in the real world. In order to overcome the above restriction, in the last previous research [1], we have proposed and developed a modified immersion test in describing the effect of water infiltration of the flood puddle phenomenon. The study succeeded to grasp the deterioration of the asphaltic mixture durability. However, due to the restriction of the extended immersion duration, the fully understanding could not be achieved. In this regard, the present research attempts to continue the previous research, particularly, in addition of the immersion duration. In other issue, recently years many countries face environmental problems such leaving the waste materials [4]. Particularly in developing countries, they have almost no rules to protect the environment against wastes. In this regard, many countries have been working on how to reuse the waste material, so that they can reduce the hazards to the environment [5]. The 127404-6161-IJCEE-IJENS © August 2012 IJENS IJENS International Journal of Basic & Applied Sciences IJBAS-IJENS Vol:12 No:04 wastes can be utilized in producing new products or can be used as admixtures. Then, natural sources using is more efficiently, and it protects the environment from the waste deposits. Regarding the solving problem of the wastes, this study attempts to utilize the marble waste as a substituted filler material on an asphaltic concrete mixture. During the cutting process, about 25% marble result dust [6]. In Indonesia, sedimentation settles and leaves the marble dust directly in situ which result in ugly appearance of the environment. It is also causing dust in the dry season and threat both to agriculture and health. Addressed to the marble waste utilization, many studies have used the waste particularly as filler in the concrete mixture [6, 7, 8, 9, 10]. Only a few previous researches on utilizing the waste in asphalt mixtures as filler material. For instance, Karasahin et al. [5] and Akbulut et al. [11] have used the marble waste in asphaltic concrete mixture. In regarding to contribute and to extend on both above issues, the influence of the flood puddle and utilization of the marble waste, the present research aims to conduct an experimental study in order to grasp effects of the flood puddle to durability of the road pavement, particularly the asphalt concrete mixture utilizing the marble waste as a substituted filler material. The study carries out modified immersion test to represent the phenomenon. The research adopts three types parameters of durability indexes to describe the asphalt mixture durability, i.e. the retaining strength index (RSI), the first durability index (FDI), and the second durability index (SDI). The remainder of we compose this paper as follows. The next chapter presents the methodology of the experimental study. Then, Chapter 3 demonstrates the results of the experimental activities and discussion related to the results. The final chapter provides conclusion and summarizes key findings. II. METHODOLOGY OF THE LABORATORY EXPERIMENT A. Immersion test to represent flood puddle phenomenon This research adopts a modified immersion test in order to represent treatment of the flood puddle phenomenon on asphalt pavement in the real world. The test is an extended immersion test from the Marshall Immersion test. The following paragraphs explain the procedures of the test. Regarding AASHTO and SNI [12, 13], the Marshall Immersion test starts from the preparation of test specimen of an asphalt mixture. Standard size of the specimen is 7.5 cm in high and 10 cm, in diameter. The immersion process is conducting at 60oC during 24 hours (one day). After finished the immersion period, the surface of specimen is visually testing for remarkable of stripping and an estimated until nearest 5% of the residual coated area. Resistance of the asphalt mixture to water damage is carried out by measurement on changing in stability values of the specimens. In this regard, we conducted the Marshall stability test to the specimens that divided into 2 (two) groups specimens sampling, i.e. a group of specimen that 7 treated immersion in water at 60oC during 30 minutes, and a group for immersion during 24 hours at the same water temperature. Further, in order to indicate effects of the flood puddle to durability of the asphalt mixture after immersion period over 24 hours, we have developed a modified immersion test [1]. The immersion test conducted extended duration, which more than one day immersion for some immersion periods, e.g. 4, 7, and 21 days immersion. Three specimens for each immersion period are preparing, and then the specimens are immersing in water at 60oC according to their immersion duration. After the immersion, the Marshall Immersion test procedure measures the Marshall stability of the specimens. B. Durability indexes of asphalt concrete mixtures In order to represent the retaining strength of an asphalt mixture after treating the Marshall Immersion and the modified immersion tests, this study use three types of durability index. The following paragraphs explain the three indexes. Firstly, the value of the retaining strength index (RSI) of a Marshall Immersion test is obtaining by using the below equation [12, 13]: RSI S2 x100% S1 (1) Where, S1 and S2 are values of the Marshall stability tests (in unit kg) after immersion during T1 and T2 minutes, respectively. The minimum value of the RSI that showed an asphalt mixture still enough stable is 75%. In other words, the limit value of the RSI indicates that bituminous mixture is assuming to be strong enough to hold on damage caused by the influence of water when the IRS value is equals or more than the limit value. Secondly, the first durability index (FDI) formulates its value as follows [1, 2, 3]: n 1 FDI t 0 S i S i 1 t i 1 t i (2) Fig. 1. The conception of the FDI and SDI Where, Si, and Si+1 are the percentage of the retaining strength after the immersion during ti and ti+1 day, respectively. 127404-6161-IJCEE-IJENS © August 2012 IJENS IJENS International Journal of Basic & Applied Sciences IJBAS-IJENS Vol:12 No:04 As shown in Fig.1, the positives values of the FDI indicate stability lost, while the negatives values indicate stability obtained. In application, usually the FDI represents percentage of stability lost for one day of test [1, 2, 3]. Thirdly, the second durability index (SDI) formulate its value as follows [1, 2, 3]: 1 n 1 n 1 SDI Ai S i S i 1 2t n t i t i 1 (3) t n i 1 2t n i 0 Where, tn is the considered total duration of immersion, while Ai represents the square of lost strength for i immersion period. According to the Equation (3), the SDI means the wide area of stability lost that located between the durability curve and So [1, 2, 3]. This index also represents the stability lost in a day when its value is positive. In contrary, the negative value indicates the stability gained as the former index, the FDI. Those durability indexes are useful in describing the lost stability or strength of an asphalt mixture appropriately. In describing the stability lost in term of the ratio between two stability values, the RSI is appropriate. On the other hand, the FDI is more appropriate in describing the strength difference between two stability testing results on the two time periods serially. As well as, the SDI for the stability lost in term of the wide area. C. Steps of the experimental activities This study consists of four steps experimental activities in a laboratory. The first step is a set preliminary laboratory test on aggregates and asphalt materials properties using the Indonesian Specification for Asphalt Concrete Mixtures [13, 14], British Standard, and AASHTO. The second step is activities to obtain the optimum asphalt content (OAC) of each asphalt concrete mixture. In this regard, there are three variations of the mixtures, i.e. asphaltic concrete containing 100%, 50%, and 0% marble waste as filler (Here after called AC1, AC2, and AC3, respectively). In order to determine the OACs of the AC mixtures using Marshall testing, the asphalt contents of each mixture are varying from 4.5% to 6.5%, at 0.5% increment. Furthermore, specimens of each mixture type under the optimum condition are preparing for the continuous steps. The third step is the Marshall Immersion test providing the retaining strength index (RSI) of the asphalt mixtures in optimum condition. The fourth step is the modified immersion test in obtaining both durability indexes of the mixtures, the FDI and the SDI. III. RESULTS AND DISCUSSIONS A. The Aggregates and Asphalt Properties Results of the preliminary laboratory test including aggregates properties, asphalt properties, and design mix of the asphaltic concrete mixtures are providing as follows. This study used coarse and fine aggregates (i.e. crushed rock and sand respectively) from stone crusher in Bili-Bili, Gowa Regency, Sout Sulawesi, Indonesia. The fillers of the asphalt 8 concrete mixtures are “stone-dust” and marble waste as a substituted material.

Table 1 shows the results of those tests. The table shows that the aggregate properties fulfilled the limit of the AC specification. Therefore, the aggregate materials could be used TABLE II The asphalt (Pen 60/70) properties Characteristics Penetration (25˚C,5 sec., 100gr) Ductility (25˚C,5 cm/minute) Softening point (Ring & Ball) Flash point (Clev.

The asphalt type, which used in this research, is petroleum asphalt (Pen 60/70) from asphalt storage of Indonesia Civil Work Department branch South Sulawesi Province in Makassar, Indonesia. The laboratory tests conducting in this study include penetration, ductility, softening point, flash point, burning point, specific gravity, loss of weight, and solubility properties. Table 2 presents the results of these tests. The table shows that the asphalt properties fulfilled the specification limits. Then, the asphalt could be used in producing the specimens of the asphalt concrete mixtures. The Marshall test regarding the AASHTO or ASTM method is conducted in order to obtain the optimum asphalt content (OAC) of the AC1, AC2, and AC3 mixtures, respectively. The method considers six parameters, i.e. Marshall Stability, Marshall Flow, Marshall Quotient (MQ), VIM, VIM, VMA, and VFWA. Table 3 provides the values of those parameters of each mixture. Through an optimizing of the six parameters to specification values of SNI 1998, OAC resulted about 6.30%, 5.96%, and 6.18% for the AC1, AC2, and AC3 mixtures, 9 AC mixture still has significant strength or durability. Generally, the RSI values of the mixtures until fourteen days of the immersion are upper than 80%. Table 3 and Figure 3 show that the FDI values of the AC mixtures increase in following the immersion duration until the immersion days achieve seven days. Then, the FDI values of the Fig. 3. The FDI values of the mixtures Fig. 4. The SDI values of the mixtures Fig. 2. The RSI values of the mixtures respectively. In addition, Table 3 shows that mostly parameters values fulfill the specification of the AC mixtures. B. Durability index of the asphaltic concrete mixtures The stabilities values resulted from the treatment of the immersion test and its modifying during 1, 4, 7, and 14 days of the immersion on the specimens of each mixture type, determine the three durability indexes values (i.e. RSI, FDI, and SDI). Figure 2 presents the RSI values of the three AC mixtures. According to the RSI curve in this figure, the parameters values of the FDI and SDI are calculated, and the results are shown in Table 3, Figure 3, and Figure 4 respectively. Figure 2 shows that the RSI values of all mixtures decrease in following the increasing of the immersion days. In comparing among the three AC mixtures, the figure shows that the AC3 mixture is better than both AC mixtures (i.e. AC1 and AC2) which containing marble waste as the filler. In addition, the AC1 mixture has the lowest RSI values of the three AC mixtures. Even though, the RSI values of the three AC mixtures are still more than 75%, a minimal value of RSI to obtain that an mixtures decrease for the extended immersion days, except the AC2 mixture that still slightly increase. Figure 4 shows the similar phenomenon for the SDI values, even for the AC2 mixture. These results indicate that the mixtures achieved their ultimate of the strength lost on the seven days of the immersion. Furthermore, in comparing the FDI and the SDI values 127404-6161-IJCEE-IJENS © August 2012 IJENS IJENS International Journal of Basic & Applied Sciences IJBAS-IJENS Vol:12 No:04 IV. among the three mixtures, the FDI and the SDI values are similar to the RSI values phenomenon. In this regard, the AC1 is superior to the others two, while the AC1, the mixture containing 100% marble waste as the filler material, is the mixture which has the biggest of its strength lost. C. Discussion Regarding the RSI values, the three mixtures have significant sensitivity related to retained strength of the mixtures during the immersion days that conducted in this study. The RSI values indicate that the mixtures still are upper than 75% after fourteen days immersion. However, the decreasing of the RSI values occurs smoothly during the treated immersion for the three mixtures types. In addition, the FDI and SDI values also show a similar trend with the RSI values. Both durability indexes indicate the availability deterioration of the mixtures durability. The seven days immersion became ultimate point of the strength lost of the three AC mixtures. Furthermore, the comparison of durability deterioration among the three mixtures shows that the AC3 mixture is more durable than the others two mixtures from the influence of the flood puddle phenomenon. On the other word, utilization of the marble waste as the substituted filler material of the asphalt concrete mixture caused the mixture more deterioration from the water infiltration. However, this utilization could not decrease the stability values of the mixtures in passing the specification limit of an asphaltic mixture, even the utilization of the waste until 100% as the substituted filler. Overall, these results provide an expectation in promising the utilization of the marble waste as the substituted filler on the asphalt mixture of the road pavement. Finally, the modified immersion test has succeeded to describe the effect of the flood puddle on the deterioration of the durability of the asphaltic concrete mixture in the real world TABLE IV Parameter values of the FDI and SDI of the mixtures Mixture Types Immersion Duration (Days) AC1 (100% Marble Waste) AC2 (50% Marble Waste) AC3 (0% Marble Waste) 4 7 14 Total 4 7 14 Total 4 7 14 Total First Durability Index (FDI) r R ( % hr) (kg/hr) 1.052 12.530 3.368 40.123 0.996 5.084 5.416 58.037 0.564 6.665 1.568 18.529 1.647 8.341 3.779 33.535 0.342 3.559 1.015 10.664 0.364 3.828 1.721 18.051 Second Durability Index (SDI) a A ( %hr) (kg/hr) 2.59 30.88 6.13 73.08 0.75 8.90 9.47 112.86 1.39 16.42 2.86 33.75 1.24 14.6 5.49 64.7 0.84 8.87 1.85 19.42 0.64 6.7 3.33 34.99 through the adopting three types of durability indexes, i.e. RSI, FDI, and SDI. 10 CONCLUSSIONS The influences of the flood puddle disaster on the durability deterioration of the road pavement, particularly, the surface layer or the asphalt concrete mixture utilizing the marble waste is the primary study in this paper. The flood puddle phenomenon occur in the rain season, in tropical countries, usually causes the road pavement under water or awash. In this regard, we have conducted an experimental study in the laboratory, such the modified immersion test which represented the real world phenomenon. The experiment treated immersion tests for 1, 4, 7, and 14 days against the three types of asphalt mixture, i.e. the asphalt concrete mixture containing marble waste 100%, 50% and 0%, namely AC1, AC2, and AC3, respectively. In order to grasp the influences of the flood puddle on the durability of the AC mixtures, this study analyzed the experimental results using three types of durability index, i.e. the retaining strength index (RSI), the first durability index (FDI), and the second durability index (SDI). The first one of the three represents the durability of the mixtures when treated by Marshall Immersion test. The others two represent the durability results of the mixtures after treated by modified immersion test. The experimental results show that the three AC mixtures still have significant RSI values for treated the Marshall Immersion and the modified immersion tests. These results indicate that the AC mixtures containing the marble waste as filler are still enough durable to retain the flood puddle phenomenon until fourteen days. However, the asphalt mixtures have experienced smoothly decreasing of the RSI value in following the increasing of the immersion duration. In addition, the FDI and SDI values of the AC mixtures also indicated that deterioration of durability of the asphalt mixtures achieved the ultimate strength lost on seven days of the immersion. Briefly, the modified immersion test provides significant performance in order to grasp the asphalt mixtures durability deterioration due to the flood puddle during some days. We expect that the extended immersion duration of the asphalt mixture in order to grasp the more strength lost need to be studied further. In the other side, the utilization of the marble waste as a substituted filler on the asphalt mixture seems a promising as a friendly environment effort in reusing the waste.
