Simulation test testing device for asphalt concrete pavement water destruct

Abstract

The invention relates to a simulation test device of moisture damage on pitch concrete road, which comprises a shell made from transparent material, a groove on the upper of the shell, a pitch concrete sample in the shell, a heater and a refrigerator in the sample, a plurality of test points on different positions on the shell, resistivity test points provided on the test points and connected with a test device outside the shell via wires, and a plurality of cameras on different parts of the shell. When in use, user sprays colorful water on the upper of the pitch concrete sample, after permeation, uses a roller to roll in the groove, uses the heater or refrigerator to simulate the internal temperature change of pitch concrete road, uses high-speed camera to record the water condition of roadbed section, tests the resistivities of different regions to obtain the water distribution and obtain the rule and reference of roadbed pore water damage on roadbed, therefore, user can take relative processes to reduce road damage and save resource.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a simulation test device for water damage of asphalt concrete pavement, which can visually observe the damage of water to the asphalt concrete pavement. Background technique [0002] We know that the pavement structure design in my country currently does not consider drainage inside the pavement (or structural layer), nor does it consider preventing water from invading the base layer. destructive effect. [0003] A very important reason for the damage of asphalt pavement in highway engineering is caused by water. The sources of water in the asphalt pavement are ground precipitation and water squeezed up from the roadbed. Atmospheric precipitation seeps into the asphalt pavement and cannot be drained out. Under the action of vehicle load and temperature change, the asphalt pavement is damaged. In winter and spring, snowfall (after melting during the day) and precipitation seeped into ...

AI Technical Summary

Problems solved by technology

[0013] At present, there is no device for visually measuring and observing the pressure of water in the road surface, and the damage situation in the road surface cannot be determined in advance, and the damage to the road cannot be prevented in advance
