The test device of the communicated water flow of pavement under tires can simulate the seepage situation of the asphalt pavement after dynamic water pressure is generated under the load action of the tires, and water seepage coefficients of the asphalt pavement are measured under the condition, so that test accuracy can be improved, actual measurement requirements are met, and broad application prospect is realized.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and relates to a device for simulating water seepage of an asphalt pavement after hydrodynamic pressure is generated under the action of a tire load and measuring the water seepage coefficient of the asphalt pavement under this condition, in particular to a tire pavement connected water flow test device. Background technique [0002] Pavement water seepage coefficient is one of the key technical indicators to measure pavement drainage performance. The accuracy of pavement water seepage coefficient measurement is related to the safety of traffic in rainy days and the degree of road water damage. But there are following deficiencies in existing water seepage meter at present: [0003] 1. The existing water seepage meter can only measure the water seepage coefficient of the road surface under hydrostatic pressure, but on the real road, the vehicle load travels on the road surface, the road ...

Problems solved by technology

[0003] 1. The existing water seepage meter can only measure the water seepage coefficient of the road surface under hydrostatic pressure, but on the real road, the vehicle load travels on the road surface, the road surface water moves under the action of the vehicle load and generates dynamic water pressure on the road surface, the existing water seepage meter cannot be very Good simulation of the real road conditions;

[0004] 2. The existing water seepage meter can only measure the seepage coefficient under one state, that is, the pavement seepage coefficient under hydrostatic pressure, but cannot measure and compare the pavement seepage coefficients under various states;

[0005] 3. The existing water seepage meter will be in a tilted state on the road surface when there is a certain slope on the road surface, resulting in measurement errors;

[0006] 4. The existing water seepage meter does not adopt an integrated design, the installation and disassembly are very troublesome, and it is easy to fail the experiment due to installation errors
