Abstract
White topping is a technology to construct 50-100mm thick cement concrete overlay on distressed asphalt pavement as a rehabilitation technique. There have been several White topping projects completed in India, the first in Pune, subsequently in New Delhi, Ghaziabad, Mumbai, and Thane. All projects have shown good to excellent performance so far, indicating that this rehabilitation strategy can stand up to the Indian climate and traffic conditions. The suitability of white topping rehabilitation for a particular site is dependent on several factors, including existing asphalt thickness, volume of truck traffic, base and sub-grade support, and pavement conditions. This report outlines the state-of practice in India for construction of white topping considering mix traffic, extreme climatic conditions, use of indigenous materials.
