Life-cycle cost analysis of optimal timing of pavement preservation

Zilong WANG,Hao WANG

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 1,   Pages 17-26 doi: 10.1007/s11709-016-0369-3

Abstract: This study developed an integrated life-cycle cost analysis (LCCA) model to quantify the impact of pavementpreservation on agency cost and vehicle operation cost (VOC) and analyzed the optimal timing of preservationThe traffic loading and the initial IRI value significantly affects life extension and the benefit ofagency cost caused by pavement preservation.The benefit in VOC is one to two orders greater in magnitude as compared to the benefit in agency cost
