| 摘要： | The large and ever-increasing investment demands for the upkeep and for ensuring the desired level of serviceability of road infrastructure facilities that were created at great cost have concerned administrators, policy makers, and highway professionals in India, and caused them to seek appropriate solutions, in view of resource constraints, for road maitnenance and rehabilitation problems. The development of a pavement management system for different conditions prevailing in the country is a step in this direction. A number of studies have been completed for achieving this objective, and a long-range project entitled the Pavement Performance Study (PPS) is in progress; its goal is to develop data for a total transportation cost model for Indian conditions. The part of the PPS project on Existing Pavement Sections was completed recently, and pavement deterioration models have been developed. Separate models are available for estimation of different modes of distress for different types of surfaces. The study plans and the models developed under the study are presented, their limitations are described, and future work plans are discussed. The influence of pavement structure, traffic, and environmental factors on the progression of cracks and roughness is illustrated. |
