Investigating and Comparing Traffic Induced and Restrained Temperature Stresses in a Conventional Rigid Pavement and Semi-Rigid Layers

摘要

The paper investigates and compares the magnitude of restrained temperature stresses that can udbe achieved in both a rigid pavement and a flexible pavement with a grouted macadam udsurfacing. The analysis is based on well known Westergrad equation that commonly applicable udfor concrete and BISAR from Shell that used for flexible pavement A hypothetical pavement is uddesigned to assess the properties of the materials under traffic induced stresses and temperature udrestrained stresses. The results indicate that grouted macadams could be as vulnerable to udcombinations of thermal and traffic stress as concrete and with respect to traffic induced stresses udat the underside of the surfacing layer. westergaard's analysis is more applicable to the a concreteudslab and BISAR is more suitable for grouted macadam surfacing
