Yala Construction Co Pvt Ltd
Microsurfacing, a new technology for maintenance of roads has been introduced in India under
the brand name of Macroseal. Yala Construction Co. Pvt. Ltd. and Elsamex, S.A. Spain have
proven expertise in this field for the past three decades around the world. Being economical,
durable and quick in laying, this technology is in use the world over for a very long time as a
routine form of maintenance in preference to the conventional over lays of hot mix.
We at Yala Construction Co Pvt Ltd are proud to introduce ourselves as a part of Elsamex
Group of companies of India. The Elsamex Group of Companies in India is a part of Elsamex
SA - Spain proud to introduce ourselves as an international organization; head quartered at Spain
and involved in road maintenance technologies worldwide. It specializes in preventive
maintenance technology of pavements, using cold polymer modified emulsion – MACROSEAL
and Operation and Maintenance of roads, highways and civil infrastructures. We are pleased to
introduce “Yala Construction Co. Pvt. Ltd.” as our Indian organization engaged mainly in the
field of highway design, construction and maintenance
MICROSURFACING
Macroseal – cold micro asphalt concrete has been extensively used in many countries viz. USA,
Canada, Italy, Malta, Thailand, Korea, Indonesia etc to mention a few. Many million square
meters of road have been resurfaced using this product with very good results over a period of
time.
A study was initiated for use of Bitumen Emulsion (Cold Process) to maintain Delhi Roads by
the State Govt. / PWD as a suitable alternative method for maintenance of roads in the light of
ban imposed by Hon’ble Supreme Court on Hot Mix Plants in the state of Delhi. The study was
conducted by M/s Elsamex S.A. of Spain with the active involvement of Central Road Research
Institute (CRRI) New Delhi. In the report specifications for the use of Cold Emulsion for
maintaining various types of roads were standardized with the latest state of the art technology.
The copy of the study report was presented by the foreign experts and discussed in detail at a
seminar held at Vigyan Bhawan on 28th Aug. 2000 in the presence of engineering technocrats
from Delhi Public Works Department, State Public Works Departments, New Delhi Municipal
Council (NDMC) & Ministry of Road Transport and Highway (MORT&H). The study report
was accepted and a go ahead was given for the use of the technology for maintaining the roads of
Delhi. Subsequently, Ministry of Road Transport & Highway (MORT&H) has also included the
specifications in Clause 516 towards slurry seal.
The performance of the Micro Seal over the years has been excellent and found to be of very
high standards. Based on the performance & the studies carried out, the IRC brought out their
tentative guidelines (Specifications) for Slurry Seal and Microsurfacing in IRC SP-81-2008. The
specification is also included in the specification on road work issued by ministry of road
transport highways in 2004 as Slurry Seal.

Microsurfacing is a fast and durable pavement preservation technique that utilizes the benefits of
cold-mixes using rubber / polymer modified Bitumen Emulsion, fine aggregate and special
additives, spread on the structurally sound pavement using special computerized paver, spread in
a thin film. Microsurfacing provides cost effectiveness, fast application and durability where
pavement is in distress or where pavement life extension is required before distress has occurred.
This technology utilizes the advancements of Asphalt Emulsion technology by special mix
design done in laboratory with carefully graded crushed aggregates, modified bitumen emulsion,
fillers and break control additives that provides the complete sealing of surface. Hence this
technique can also be used for periodic renewals of roads in place of hot mix treatments.
Advantage of Microsurfacing
Advantage of Micro Surfacing with a quick-traffic application as thin as 6 to 8mm layer , Micro
Surfacing can increase skid resistance, color contrast, surface restoration, and service life to high
– speed, heavy-traffic roadways. On airfields, dense-graded Micro Surfacing produces a skid
resistant surface without loose rock that may damage aircraft engines. Because of its quick set
traffic properties, Micro Surfacing can be applied in a broad range of temperatures and weather
conditions, effectively lengthening the paving season. It is particularly suitable for night
applications on heavy-traffic streets, highways, and airfields. The major advantages are as
follows.
Advantages
1.
Very fast applications with best on- site pavement quality (imported computerized
Microsurfacing pavers used.
2.
Life span exceeds the life span of ordinary Hot-mixes.
3.
Non-polluting for Environment. No heating or hot paving required.
4.
Ideal for surface sealing treatment that improves skid resistance and provides
surface durability.
5.
Does not increase pavement height significantly (This saves from water logging,
drainage and other problems).
6.
Cost effective as compared to Hot-Mix.
7.
Reduces noise caused by movement of traffic.
The use of Microsurfacing is recommended over the DBM also as it gives a polymerized
wearing coat over the DBM, thus effecting better temperature susceptibility. It increases the life
of the wearing course and it is faster to lay. The road can be opened to traffic after a short while
once the Microsurfacing is set.
As far as costs are concern there is a saving of 20 to 25% in direct costs as compared to
bituminous concrete. In addition there is a savings in the quantities of material used as also the
Energy cost for producing Microsurfacing. The added benefit is the reduction in environmental
pollution. Besides the above there is a saving in time for construction and opening to traff
