Project Overview 

Tremendous increases in vehicle traffic over the past two decades have led to high rates of pavement deterioration on the Pakistani road system. This project addressed this problem by introducing asphalt recycling technologies to Pakistan and developing guidelines for their use. Recycling involves the reuse of existing roadway materials in the cost-effective reconstruction or rehabilitation of pavements. The price of asphalt, a product of petroleum refining, has increased many times over in recent years, so finding a way to reuse it makes economic sense. There are environmental benefits as well, as recycling pavement reduces the amount of waste that must be sent to landfills. This project, which involved several collaborating researchers at each partner institution as well as linkages with industry and government, included both technical studies of asphalt materials and policy studies of the potential savings to be realized from recycling. Based on their findings, the research team proposed implementation plans for the Pakistani highway authorities and road construction industry, and these recommendations may be found in their reports available through the links below.
