Abrasion performance parallel test device and method

Abstract

The invention discloses an abrasion performance parallel test device and method. The test device comprises two test piece supporting tables; inflatable rubber pads and spray heads are arranged above to-be-tested pieces; the inflatable rubber pads are mounted at the end parts of rotating shafts; slave gears are mounted on the rotating shafts; the two slave gears are meshed with a main gear; the rotating shafts connected with a motor drive the main gear to rotate through a speed reducer, and then the two slave gears drive the inflatable rubber pads to rotate through the rotating shafts; water tanks for discharging water are arranged below the to-be-tested pieces; the test piece supporting tables are supported by hydraulic pumps; stress sensors are buried in the to-be-tested pieces in advance; test data of the stress sensors reflects pressures of the inflatable rubber pads on the to-be-tested pieces; the test piece supporting tables are lifted under the action of the small hydraulic pumps; and the test temperature of the to-be-tested pieces are controlled through a temperature control device. A test result is obvious in comparability and can reflect the influence of different tread patterns and different tire pressures on the surface abrasion effects of the tested pieces more really.

Description

technical field [0001] The invention relates to the field of performance testing of pavement materials, in particular to a parallel test device and a test method for wear performance. Background technique [0002] With the development of the national economy, there are more and more high-grade, heavy-traffic roads, and the requirements for them are getting higher and higher. With the passage of vehicles, the wear on the road surface is intensified, and the anti-skid ability of the road surface is reduced. Factors affecting the anti-skid performance of pavement, for asphalt pavement or cement pavement, include the nature of stone material, particle gradation, wetness degree of pavement, amount of binder, etc. At present, the indoor testing methods for pavement anti-skid performance mainly include sand-spreading method and pendulum method. [0003] The sand paving method is to test the surface structure depth of asphalt pavement and cement concrete pavement, which is used to ...
