Test device and method for testing dynamic water scouring resistance of asphalt pavement

Abstract

The invention provides a test device and method for testing the dynamic water scouring resistance of an asphalt pavement, and the device comprises a supporting platform and irrigation equipment; the bottom of the supporting platform is provided with an opening, and an asphalt test sample surrounds the opening; and the irrigation equipment comprises a water container, a first valve, a mounting base, a first elastic piece, a guide device and a limiting rising device, and the first valve used for opening and closing the bottom of the water container is mounted at the bottom of the water container; the mounting is installed at the bottom of the water container, the first elastic piece is installed between the mounting base and the supporting platform, the guiding device is installed between the mounting base and the supporting platform, and the height limiting device is installed between the mounting base and the supporting platform. The test device and method for testing the dynamic waterscouring resistance of the asphalt pavement solve the problem that in the prior art, a test result is inaccurate due to the fact that a top plate is only placed at the top of the asphalt test sample.

Description
