Abstract
Asphalt concrete wearing course is provided on highways throughout the world to provide a smooth and watertight surface for comfortable ride. Majority of highways including motorways in Pakistan are facing acute rutting problem. Research has been conducted by various agencies to investigate causes of such failures. A number of techniques have been used to reduce these distresses, but these techniques either do not work or they are uneconomical. Pakistan, National Highway Authority (NHA) is gradually shifting towards reinforced concrete lanes for heavy traffic, which are far more expensive than asphalt concrete roads. A new technique of using tempered glass is being proposed as replacement of asphalt concrete wearing course in highways. The innovative technique may provide a solution to the chronic problem of highway distresses.
