Bituminous pavement water seepage meter under dynamic water effect and use method of bituminous pavement water seepage meter

Abstract

The invention relates to a bituminous pavement water seepage meter under a dynamic water effect and a use method of the bituminous pavement water seepage meter. The water seepage meter comprises an upright pillar bracket, wherein a measuring cylinder is arranged at the upper part of the upright pillar bracket, is externally connected with a water source and an air pressure machine respectively through a first pipeline and a second pipeline and is connected with a cylinder body placed on a supporting platform through a third pipeline, an asphalt concrete test piece is placed in the cylinder body, the cylinder body is connected with a water containing bucket placed on a rotating platform through a fourth pipeline, and valve switches are mounted on the first pipeline, the second pipeline andthe third pipeline. A user only needs to execute core boring sampling at a testing point, and take all collected samples to a laboratory to execute unified testing, so that the problem that the meteris carried out to multiple places for testing is solved, the goal of reducing the workload of an operator is achieved, and meanwhile, the utilization rate of the operator is maximized; and an instantpopup conveying principle of a cartridge of a spring pen is utilized in the structure of the valve switches, and the valves are rapidly opened by pressing switches, so that the problem that water cannot instantly flow out is solved, and the precision of a water seepage coefficient is increased.

Description

Technical field: [0001] The invention relates to the technical field of road engineering, in particular to an asphalt pavement water seepage meter under the action of dynamic water and a using method thereof. Background technique: [0002] When a car is running on a road covered with water film, a dynamic and instantaneous water pressure, that is, hydrodynamic pressure, will be generated between the tire and the road. There are several main ways for moisture to enter the asphalt mixture surface layer. Groundwater or rainwater may penetrate into the surface layer through the soil shoulder, base layer, central divider or side slope; there are different types and degrees of cracks in the asphalt pavement. When the crack width exceeds A certain limit, rainwater will enter the asphalt mixture surface; road rainwater will enter the pavement surface under the action of high-speed driving water pressure, and induce water damage to the pavement. [0003] The current detection tool f...
