METHOD OF CALCULATING STRENGTH GRIP COATING OF AS-PHALT ROADWAY BRIDGE AT SHIFT FROM EMERGENCY BRAKING OF VEHICLE

Abstract

There has been offered the method of determining the strength of adhesion of asphalt pavement with reinforced concrete base of a bridge which takes into account the operation of asphalt pavement on concrete bridges, including the concentration of stress and significant horizontal shear strain due to the fact that at high temperatures significantly reduced elastic modulus asphalt and modulus spans bridges virtually unchanged. Using the proposed method allows to choose the most appropriate coating material with the calculated characteristics at the design stage of asphalt pavement on the concrete bridges shear resistance that will reduce operating costs during his detention.
