Abstract

The invention discloses a shock resistance testing device and a shock resistance testing method of a heat reflection type asphalt pavement coating. The shock resistance testing device comprises a temperature control part, a support part, an impaction part and an observation part, wherein the temperature control part comprises a temperature box, a handle, a temperature adjusting rotary knob, a power switch and a rope hole; the support part comprises a suspension type tray, a suspension girder, an objective table, a fixed screw, a tray hole and a baffle rod; the impact part comprises a suspension arm, an impaction ball, a force transfer rope and a handle ring; and the observation part comprises a visible window and a temperature display screen. The shock resistance testing device and the shock resistance testing method are used for testing the shock resistance of the heat reflection type asphalt pavement coating.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement coating detection, and relates to a heat reflection type asphalt pavement coating impact resistance testing technology, in particular to a heat reflection type asphalt pavement coating impact resistance testing device and a test method. Background technique [0002] Due to the black color of the asphalt pavement, the pavement has a strong heat absorption capacity, and the accumulation and accumulation of a large amount of heat will make the temperature of the pavement continue to rise, and it is easy to produce flow deformation under the action of external loads, thus forming ruts . The generation of rutting will destroy the original pavement structural strength and induce other diseases, which put forward higher requirements for the high temperature stability of asphalt pavement. On the other hand, because asphalt pavement can effectively store solar radiation, each asphalt road has bec...
