Abstract
In the article, based on literature analysis [1-3], a basic calculation scheme was developed for determining horizontal normal stresses in reinforced asphalt concrete coating with basalt fiber on reinforced concrete road bridges, taking into account the different time of action of the load of vehicles, which causes tensile stresses. A method for assessing the durability of asphalt concrete pavement with basalt fiber on reinforced concrete road bridges is proposed, which is aimed at increasing its crack resistance by improving design. Such design consists in the construction and calculation taking into account the repeated application of static and short term dynamic loads of vehicles. The choice of the durability condition based on the limit state criterion for evaluating the crack resistance of the reinforced asphalt concrete pavement with basalt fiber is substantiated, taking into account the different time of the load and temperature. A method of assessing the durability of asphalt concrete pavement using basalt fiber on reinforced concrete road bridges and the sequence of its design has been developed.
