Design Procedure by Strength Criteria of Asphalt Layers on a Rigid Base Taking into Account the Simultaneous Action of External Loads and Thermal Stresses

摘要

The article gives the definition of a generalized solution of the thermal stress in the asphalt layer on a rigid base at heating and cooling, taking into account the rheological properties of asphalt concrete pavement. The equation for determining the stress state of the asphalt layer on a rigid base caused by the combined effect of temperature deformation and external load is presented. The design procedure by the strength criteria of asphalt layers on a rigid base, taking into account the adhesion strength of the asphalt layer and the rigid base, the temperature cracking resistance, as well as the shear resistance of the asphalt layer is given.
