Asphalt surfaces were said to suffer extensive deterioration in heavy rains, producing potholes and necessitating repeated repairs, and the civic administration determined that concrete overlay would offer greater strength. The white-topping method entails laying a concrete layer over the existing carriageway, which is expected to increase the lifespan of the route and reduce maintenance costs. Engineers anticipate longer intervals between repairs and lower lifecycle expenditure once the new surface is in place.
Until now, white-topping schemes in Gandhinagar were implemented by the Roads and Buildings Department (R&B Department), with the first such stretch completed from Sargasan to Rakshashakti Circle and subsequent work on the Koba-Adalaj link road. The municipal corporation will for the first time execute a white-topping project directly, taking responsibility for procurement and project management. Officials noted that local execution is intended to accelerate delivery and ensure closer supervision of construction quality.
The adoption of white-topping has been encouraged at the national level and the Union Road Transport Minister had recommended the technology for Gujarat, prompting state approval of earlier phases. Those earlier phases were estimated at around Rs 380 mn and the civic body is using those precedents to frame technical specifications and cost estimates for the current scheme. The standing committee has set completion ahead of the monsoon as a priority and has asked officers to finalise timelines, contracts and mobilise resources accordingly. Project executives will monitor progress and report to civic leadership as the works proceed.
