Asphalt concrete pavement rainwater penetration simulation device

Abstract

The invention provides an asphalt concrete pavement rainwater penetration simulation device. In this device, the circuit control board controls the opening of the first solenoid valve and the closing of the second solenoid valve, and then controls the air compressor to pressurize, so that the rainwater in the water storage tank flows into the test piece under the positive pressure. tank, and shower the asphalt concrete test block; when the pressure value of the electric contact pressure gauge reaches the set value, the circuit control board controls the first battery valve to close; at this time, the circuit control board Control the opening of the second electromagnetic valve, and then control the operation of the vacuum pump, so that the rainwater in the test piece test tank flows back to the water storage tank under the action of negative pressure; when the vacuum pressure gauge of the electric contact reaches the set vacuum degree , the circuit control board controls the vacuum pump and the second electromagnetic valve to close. The asphalt concrete pavement rainwater infiltration simulation device of the invention can accurately simulate the phenomenon of asphalt concrete pavement rainwater infiltration.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete, in particular to an asphalt concrete pavement rainwater penetration simulation device. Background technique [0002] With the rapid development of modern traffic, more and more asphalt concrete is used in road construction. [0003] Asphalt concrete is artificially selected with a certain proportion of mineral materials (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, and mixed under strictly controlled conditions. of the mixture. Asphalt pavement is a pavement structure composed of a surface course built with asphalt materials as a binder to bond mineral materials, various bases and cushions. As the asphalt pavement uses asphalt concrete, the cohesion between mineral materials is enhanced, the strength and stability of the mixture are improved, and the durability of the road surface is improved. Compared ...
