Accelerated loading abrasion device for pavement

Abstract

The invention discloses an accelerated loading abrasion device for a pavement. The device comprises a housing, a support, a loading tire, a test piece tray, a pavement slab test piece, an oil pressure self-control loading device, a loading tire power system, a carborundum scattering device, a water film thickness control valve and a temperature adjusting system, wherein an instrument control panel is also arranged on the housing. With the adoption of the device, rotating and rolling actions of the tire on the pavement can be effectively simulated, and meanwhile, effects caused by the shearing force exerted on the pavement slab test piece by the tire on a curve on the pavement is also simulated.

Description

technical field

[0001] The invention belongs to the technical field of road surface testing, and in particular relates to a road surface accelerated loading wear device. Background technique

[0002] The main modes of action of vehicle loads on the road surface are: vehicle loads acting vertically on the road surface will cause permanent deformation (ruts) on the road surface; The shear force will cause shear damage such as pushing on the pavement; the surface of the pavement is gradually polished, resulting in a decrease in the anti-skid performance of the pavement surface, resulting in safety hazards; The vibration and bonding between the tires will change correspondingly, which will increase the noise of the interaction between the road surface and the tires, and bring about the increasingly serious noise pollution faced by modern cities; Water damage occurs; due to the increase in summer temperature, the stiffness of the road surface, especially the asphalt pavement, de...
