Abstract

The invention relates to asphalt seepage testing devices, in particular to a multi-directional constant-pressure asphalt mixture seepage testing device, aiming at solving the problems that a seepage meter in the prior art is a variable-head seepage meter with the maximum head height being only 0.5m, so that seepage water pressure constancy cannot be achieved and seepage generated by vehicle load under the condition of high head water pressure cannot be simulated; divisional seepage of water flow inside a asphalt mixture cannot be studied. The multi-directional constant-pressure asphalt mixture seepage testing device comprises a seepage mechanism, a seepage mechanism holding tank, a water catcher, a water pressure pipe component, a water tank, a water tank support, a computer control element, a peristaltic pump, a first water level measurement sensor, a measuring cylinder, a second water level measurement sensor and a silicone hose, wherein the seepage mechanism is arranged in the seepage mechanism holding tank, the seepage mechanism holding tank and the measuring cylinder are arranged in the water catcher, the water pressure pipe component is communicated with the seepage mechanism, the water tank is communicated with the water pressure pipe component and the peristaltic pump, and the water catcher is communicated with a water inlet of the peristaltic pump. The multi-directional constant-pressure asphalt mixture seepage testing device is used for the field of mixture seepage testing.

Description

technical field [0001] The invention relates to an asphalt seepage test device, in particular to an asphalt mixture multidirectional constant pressure seepage test device. Background technique [0002] Water damage is the main factor that endangers roads, and it is also one of the main reasons for the early damage of asphalt concrete pavement. Gradually intruded into the interface between asphalt and aggregate, due to the hydrodynamic effect, the asphalt film is gradually peeled off from the aggregate surface, which leads to the loss of cohesive force between aggregates and the process of pavement failure. One of the main causes of water damage is the water seepage of the asphalt pavement. Therefore, it is of great significance to analyze the cause of the water seepage of the asphalt pavement and study the prevention and control measures to reduce the water damage of the asphalt pavement and prolong the service life of the asphalt pavement. [0003] The seepage of water in ...
