Title: Investigating and Comparing Traffic Induced and Restrained Temperature Stresses in a Conventional Rigid Pavement and Semi-Rigid Layers
Abstract: The paper investigates and compares the magnitude of restrained temperature stresses that can
be achieved in both a rigid pavement and a flexible pavement with a grouted macadam
surfacing. The analysis is based on well known Westergrad equation that commonly applicable
for concrete and BISAR from Shell that used for flexible pavement A hypothetical pavement is
designed to assess the properties of the materials under traffic induced stresses and temperature
restrained stresses. The results indicate that grouted macadams could be as vulnerable to
combinations of thermal and traffic stress as concrete and with respect to traffic induced stresses
at the underside of the surfacing layer. westergaard's analysis is more applicable to the a concrete
slab and BISAR is more suitable for grouted macadam surfacing
