Asphalt-concrete-pavement rainwater infiltration simulation device

Abstract

The invention provides an asphalt-concrete-pavement rainwater infiltration simulation device. A circuit control panel of the device controls a first solenoid valve to be opened and a second solenoid valve to be closed, and then controls an air compressor to perform pressurization, so that rainwater in a water storage tank flows into a test-piece experience tank under the effect of a positive pressure, and an asphalt concrete experience block is rinsed; when the pressure value of an electric contact pressure gauge reaches a set value, the circuit control panel controls the first solenoid valve to be closed; the circuit control panel controls the second solenoid valve to be opened, and then controls a vacuum pump to work, so that rainwater in the test-piece experience tank flows back to the water storage tank under the effect of a negative pressure; and when the vacuum degree of the electric contact vacuum pressure gauge reaches a set vacuum degree, the circuit control panel controls the vacuum pump and the second solenoid valve to be closed. The asphalt-concrete-pavement rainwater infiltration simulation device is capable of accurately simulating rainwater infiltration phenomenon of an asphalt concrete pavement.

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 ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an asphalt concrete pavement rainwater penetration simulation device to overcome the phenomenon that the asphalt concrete pavement rainwater infiltration cannot be accurately simulated in the prior art, so as to ensure that the heavy metals and organic matter leached from the rainwater can be effectively analyzed in subsequent experiments
