ABSTRACT:
A pavement having one or more surface layers overlaying one or move base layers disposed on a subgrade with a rigid base layer interposed therebetween. The base layers are composed of paving material. The surface layers are composed of flexible paving material. The bearing member separates the surface layers from the base layers and has about the same longitudinal and transverse dimensions as the surface layers. The bearing member is composed of a substantially aggregate-free or aggregate free material. The bearing member is sufficiently rigid to at least generally prevent any surface layers from conforming, during the useful life of the base layers, to irregularities of the base layers and to move with the surface layers as a unit in response to movement of the base layers.
