Introduction Pavements already exist since the late 1700s which is the first pavements were built by the idea of Thomas Telford. As we know, now pavements are one of the important things for road construction. Lately in Malaysia, we often see many vehicles passing on the highway. The number of these vehicles make the road become more crowded from day to a day. The trigger of road density in addition to the number of vehicles is due to driving knowledge and damaged road conditions. In general, damaged roads such as cracking, corrugation, and damage to grooves extending along the road around the vehicle wheel rutting are also in the form of asphalt pavements on the bleeding surface, and there are also holes (pothole). This damage can occur on the road surface using asphalt concrete as the surface layer. Damaged roads like this usually caused by a variety of factors, for example, due to heavy vehicle wheel loads (frequent), high groundwater conditions, the consequences of wrong execution time, and due to planning errors. Pavement condition index (PCI) is a system for assessing road pavement conditions by type, the level of damage that occurs and can be used as a reference in the maintenance business. The PCI method provides information on pavement conditions only at the time of the survey but cannot provide a predictive picture in the future. However, by periodically conducting condition surveys, information on pavement conditions can be useful for predicting future performance, as well as being able to be used as a more detailed measurement input. Norzahanim Binti Mohd Yunus et al, Project Bfc 31802 : PCI 2 Literature Review Pavement Condition Index (PCI) is a method of assessing pavement conditions developed by the U.S Army Corps of Engineers, expressed in the Pavement Condition Index (PCI) index. The use of PCI for the roads and parking lots has been widely used in Malaysia. In the PCI method, the degree of pavement damage is a function of 3 main factors, namely: 1. Distress type According to Shahin (1994), there are 19 types of damage to the flexible pavement in the PCI method, among which are: alligator cracking, bleeding, block cracking, bumps and sags, corrugation, depression, edge cracking, joint reflection cracking, lane/shoulder drop off, longitudinal & transversal crack, patching and utility cut patching, polished aggregate, potholes, railroad crossing, rutting, shoving, slippage cracking, swell, weathering/ravelling. 2. Distress severity The severity of pavement damage on the PCI method, divided into 3 levels, namely low (l), medium (m), and high (h). Determination of the severity for the type of damage has been defined by the PCI method clearly in accordance with ASTM D 6433.3. 3. Distress quantity Distress quantity relates to measurement, measurement unit, and total quantities on the survey form. Fig. 2. Relationship type of damage, severity, and size of damage to the determination of PCI value and Standard Rating Scale (Source: Shahin 2004) Assessment of Pavement Conditions, influenced by 5 factors, namely: 1.

Pavement Quality Qualified 3.0 BACKGROUND OF STUDY In this study, an attempt was made to evaluate and suggest a suitable method to repair the damage of pavement, located in Semenyih, Selangor. This road is used for transporting goods and people, with a large percentage of heavy vehicles moving on it. This road is located at Persiaran Bandar Rinching, which is 1.0km long. It is a two-lane road, with one lane in each direction, and it is an asphalt pavement road. Figure 1 shows the location of our study. Norzahanim Binti Mohd Yunus et al, Project Bfc 31802 : PCI Figure 1 shows the location of our study 4.0 OBJECTIVE 1. Find out the type of damage to the road pavement at the location 2. Identify the extent of damage during site observation 3. Find out which method to repair the pavement at the location 5.0 METODOLOGY For any pavement maintenance and/or management activity, the knowledge of its condition is the basic requirement. Therefore, there is a need for a standardized method for assessing the condition of the pavement. After the condition of a pavement has been determined, only then a decision as to the need for maintenance can be made. The process of measurement or evaluation of Pavement Condition Index is graphically shown in Figure 3 Figure 3: Flow Chart for Evaluation of PCI 5.1 Literature Review Comprehensive summary of previous research on the topic. For this topic, it explains about Pavement Condition Index (PCI) and the meaning of distress type, severity and quantity. 5.2 Pavement Condition Survey Pavement condition surveys give an indication of the serviceability of the road pavement and the physical condition of the assets. It is referred to as the collection of data to determine the ride quality and structural integrity of a road segment. They are based on observations by trained to measurements surface distress. 5.3 Collection Data Data collect is procedure of collecting, measuring and analysing accurate insight for research at Semenyih, Selangor. It was collected for according of section. They collecting to find the deduct number of the distress 5.4 Calculation of Pavement Index Its numerical index between 0 and 100, which is used to indicate the general condition of a pavement section. It is a statistical measure from manual survey of the pavement. 5.5 Discussion Delve the meaning, importance and relevance of result. It should focus on explaining and evaluating on what already found, showing how it relates to literature review and making the argument in support of overall conclusion. 5.6 Result The result of a calculation that is calculated using the data collected. Norzahanim Binti Mohd Yunus et al, Project Bfc 31802 : PCI 5.7 Conclusion Last part of something or an opinion reached after some thought. For example, conclude about all distress that already found and calculated. 6.0 DATA ANALYSIS 6.1 Dividing a Pavement Section into Sample Units The number of sample units in a pavement section to be inspected can be determined using Figure 4.

In section one and section three, the PCI is in fair and good condition. In the fifth road section, the PCI result is in very poor condition while in the seventh section is in serious condition. This shows that along 1km of the road, we can determine common types of road distress level and determine the maintenance that should be implemented in each of the road sections. The first common distress that is found in Persiaran Bandar Rinching is potholes. Potholes generally are big and serious, which is usually less than 4m. Potholes located in section seventh of 1 km Persiaran Bandar Rinching road are categorized as deep potholes. While section fifth is categorized in both conditions which are larger and small potholes. Potholes are measured by counting the number that are low, medium, and highseverity and the pavement distress located at this road are level high-severity. The distress on the road will put people at risk, measures should be taken to avoid incidents and affect people's good driving quality. Corrective or reactive maintenance is performed after a pavement deficiency such as friction loss or extensive cracks has occurred. Alligator cracking is a common type of distress in asphalt pavement. The following are most closely related to fatigue cracks, which are characterized by interconnected or interlocking cracks in the asphalt layer that resemble the skin of a crocodile. Based on the results, most of the road sections at Persiaran Bandar Rinching have alligator cracking distress. The road sections that are affected by alligator cracking are road section one, fifth and seventh. Mitigation and maintenance measures need to be taken on these roads as the breakdown can lead to much larger mishaps such as potholes or premature lane failure, and even in advanced cases, repairs can be very costly if not done as soon as possible. Proper repair may include first sealing cracks with crack sealant, installing paving fabric over a tack coat, or milling the damaged asphalt. An overlay of hot mix asphalt is then placed over the completed repair. A patch is defined as an area where the original pavement has been removed and replaced with a filler material. Deterioration of a patch typically progresses at a higher rate than the original pavement. Patching is usually divided into three types which are small, medium and high. In this project we found that there were patching distress detected along roads only in the third section, fifth and seventh. For section fifth, there can be classified low and medium severity distress categories. Then, section seventh is only in medium severity. All flexible pavements require patching at some time during their service life. Defective pavement and unstable surface materials are removed to a stable material depth, which is normally found only 5 cm below the road surface. 8.0 DISCUSSION ON MAINTENANCE As the average of the PCI value is 54, it shows that the road is in a poor condition. Maintenance that must be finished on this road is major rehabilitation or deferred action. Major rehabilitation consists of structural enhancements that both extend the service life of an existing pavement and/or improve its load-carrying capability. Pavement rehabilitation shall be defined as resurfacing, restoration, and rehabilitation (3R) work consisting of structural enhancements that extend the service life of an existing pavement and improve its structural capacity. Rehabilitation strategies consist of recovery remedies and structural overlays. This can also additionally consist of partial recycling of the existing pavement, placement of additional surface materials or other work that is required to restore an existing pavement to a structural or functional condition. The pavement rehabilitation process includes the following procedures. Firstly, prioritization of the pavement in need of rehabilitation, which includes follow-up activities to assess the functional and structural condition of the pavement. Secondly, development of can implemented rehabilitation strategies. Next, selecting the most cost-effective remediation strategy considering several constraints, which may include reduced service life, life-cycle costs, and budget constraints, and finally, an appropriate performance measurement of the remediated pavements. Norzahanim Binti Mohd Yunus et al, Project Bfc 31802 : PCI Asphalt pavement rehabilitation generally involves renewing the existing pavement to mitigate the effects of ruts, cracks and other defects. The thickness of the resurface may depend on the condition of the existing roadway, the expected future truck traffic and the resources available. Efforts should be made to increase the flow of traffic through the zone with better scheduling of development activities, use of appropriate and realized paving materials and community education. 9.0 CONCLUSION To sum up, the objectives of this study were achieved to use pavement condition index (PCI) and produce a rehabilitation method based on the road located at Persiaran Bandar Rinching, Semenyih. From the data record that has been taken there are various types of damage involve damage to the pavement such as potholes, alligator cracking, patching and depression. In this project, the 1 km distance we divided into 5 sections. Based on the data we found that section one and three was fair and good condition. Another three section which is section five and nine was very poor and poor condition. But for section seven is in serious condition. Based on the pavement condition index rating scale, the average for all section is 54%. Looking at the average pavement condition index value ranking 54% falls in the major rehabilitation or deferred action. Results of the study have been made, and various problems occur on Persiaran Bandar Rinching, Semenyih. This distress can interrupt the consumer. Distress and failure contributed to the disorder and lead to consumer concerns. Among the most common failures are identified as malfunction and failure of the structure. Therefore, maintenance work must be carried out. Finally, the construction of the highway is a road structure that largely contributed to human comfort where it is frequently used by all users. Therefore, the parties involved, and the authorities should always notice the quality of the construction of rural roads or even roads to user satisfaction can be achieve. 10.
