Keralam PWD wary of wider adoption of white-topped roads despite proven durability

THIRUVANANTHAPURAM Although white-topped roads are considered better suited to Keralam’s climatic conditions and urban stretches, the Public Works Department (PWD) remains reluctant to adopt the technology on a wider scale, citing relatively high initial construction costs. This is despite the successful execution of a model white-topped road by the department in Alappuzha, which demonstrated the feasibility of the technology in the State. White-topping involves laying an additional layer of cement concrete over an existing bituminous (asphalt) road.

The technology offers several advantages over conventional asphalt roads, particularly in urban areas of Keralam that experience heavy rainfall, high summer temperatures and severe traffic congestion.
