Abstract:
Precast concrete pavement systems and composite pavements provide a long service life, excellent surface characteristics, and structural capacity. Composite pavements offer the additional benefits of economy and sustainability with recycled and locally available materials. Two projects of the second Strategic Highway Research program (SHRP 2) on Modular Technology and on Composite Pavement Systems, have addressed gaps in knowledge and have developed recommendations for construction specifications and techniques, life-cycle costing, and quality management. The Illinois Tollway successfully implemented these recommendations and incorporated them into the agency’s 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. By applying the SHRP 2 recommendations, the Illinois Tollway has accelerated project delivery, reduced the impact on traffic, improved safety, and achieved cost savings.
