THIRUVANANTHAPURAM: Nearly eight years after roads in the city were developed under the City Roads Improvement Project (Crip), it has been decided to give them a facelift. The Thiruvananthapuram Road Development Company Limited (TRDCL), concessionaire of Crip, has decided to carry out maintenance of the 14.256 km of road developed during the first phase of Crip in 2006.
TRDCL will submit a request in this regard to the Kerala Road Fund Board within a week. The works are expected to begin by the end of February. According to TRDCL, a technical team of IL&FS (the parent company of TRDCL) conducted a test on roads in the city last week and identified stretches which need maintenance.
"The team reported that most of the roads are in good condition. They wanted maintenance in areas that had been dug for utility works of the water authority and KSEB. Though we have done patch work at these areas, it has to be rectified so potholes won't develop soon. Besides, some portions have become smooth due to wear and tear. In such areas, there is a possibility of skidding. So we have decided to do micro-surfacing along the entire stretch," said TRDCL vice-president Anil Kumar Pandala.
In micro-surfacing, a mix of bitumen, additive and stone dust will be coated at a thickness of 2-6 mm over the road. The coat will be painted using an imported truck-mounted machine. The entire 14.256 km and some stretches in the 15 km developed during the second phase will be micro-surfaced.
"Utility works have led to the deterioration of some portions of roads developed in the second phase, which had been completed in 2009. Such areas will be repaired and will be micro-surfaced," he said.
The portions which need repair will be scraped off at a thickness of 4 cm. Semi-dense bituminous concrete and asphalt mix will be used to form a 4-5 cm thick layer over which another layer of micro-surfacing coating will be applied.
Pandala said the advantages of micro-surfacing are that it will not create a level difference on the road, will provide enough grip, prevent seepage and ensure life of at least five years.
TRDCL is planning to bring the requisite machinery from Gujarat, where it is currently being used for another work. "It is expected to take about 10 days to bring the machinery here. Meanwhile, we have to obtain the consent of KRFB. We expect to begin work by February 20-25," Pandala said.
TRDCL has estimated the cost of the work to be Rs 5-6 crore. Traffic will not be heavily affected as it plans to do the work mostly during night.
