Course C - Performance Bases Asphalt Recycling
Introduction
This short course will focus on the concept of performance-based approaches for hot and cold asphalt material recycling for use in pavement construction. The use of performance-based specifications (PBS) and the balanced mix design (BMD) concepts allow transportation agencies to use laboratory measured performance indices to recycle asphalt materials in a responsible manner while ensuring the performance of roadways are not sacrificed. Various recently developed PBS and BMD methodologies increase recycled asphalt amount will be presented along with select case studies that discuss implementation efforts of transportation agencies and construction contractors.
