Life Cycle of Hot In-Place Pavement Recycling: Case Study


Hesham Ali and Ken Grzybowski


The study examined a test section built in 2002 and a control section in 2003 to compare the cost and performance of HIR with conventional milling and resurfacing. After 8 years, in-service data were used to draw some conclusions. The test and control sections performed well. The HIR section was built at less than half the cost of the conventional section. Projections showed that HIR was cost-effective and would save 40% more than the conventional method of pavement rehabilitation.
