Warm Mix Asphalt, Asphalt Pavement Recycling and Pavement Management for Livable Communities
Abstract
The implementation of warm mix asphalt continues to grow and will become a standard practice in the world, representing the majority of the total asphalt mixture market. Another rapidly growing area is asphalt pavement recycling and the asphalt pavement in the US is 99 percent recycled. Recycled Asphalt Pavement (RAP) used in asphalt mixes is over 20 percent and continues to grow. The savings of asphalt and aggregate by using RAP in asphalt mixes were 3.6 million tons and 68 million tons per year, respectively, resulting in the saving of over $2.0 billion. Pavement surface images are collected by automated pavement distress collection systems. To automatically analyze these images, Dr. Lee developed the software called 鈥淧icCrack,鈥 which is being used by public agencies and companies in several countries.
