Effect of Pavement Roughness on User Costs

摘要: After the construction of a pavement system, deterioration occurs because traffic loading and weathering action results in formation various types distresses an increase roughness. "Roughness" can be defined as irregularities surface that affect driver safety user costs, including fuel consumption, repair maintenance, depreciation, tire costs. In this study, roughness was predicted with use newly released Mechanistic-Empirical Pavement Design Guide for levels initial condition. Four alternative maintenance rehabilitation (M&R) strategies were used to estimate life-cycle cost over 35-year analysis period. Various categories costs calculated on basis different models from data reported literature. From analysis, found dramatically. A comparison made between agency investment related ...
