Tire-type antiskid duration testing clamp for asphalt mixture and application method thereof

Abstract

The invention discloses a tire-type antiskid duration testing clamp for an asphalt mixture and an application method of the clamp. The clamp consists of a clamping groove, a connection body and tires; the clamp is fixedly connected with and fixed on a cement mortar abrasion resistance testing machine by virtue of the clamping groove at the upper part, and three tires at the lower part of the clamp are fixed onto an iron shaft of the connection body through an outer baffle plate. The tire-type antiskid duration testing clamp for the asphalt mixture employs the cement mortar abrasion resistance testing machine which is already widely used. The clamp is simple to produce and low in price; the tires on the clamp are in loaded contact with an asphalt mixture test piece, so that the tires run on the surface of the asphalt mixture in a circulating manner, the abrasion action of a running vehicle on the pavement can be effectively simulated, and the simulation mechanism is simple and direct; the variation of the antiskid performance of the mixture is tested on the basis of the variation of the mass of the test piece and the structural depth of an abraded surface, the test on the two indexes are simple and rapid and can be easily carried out. An effective tool and an effective method are provided for designing, optimizing and estimating the antiskid performance of an asphalt pavement.

Description

Technical field: [0001] The invention relates to a jig for testing the anti-skid durability of a tire-type asphalt mixture and a use method thereof. Background technique: [0002] Modern transportation has the characteristics of safety, speed, convenience and comfort, among which safety is an important requirement for use. Studies have shown that there are many reasons for traffic accidents, among which the lack of anti-skid performance of the road surface is one of the main reasons, and a good road surface structure is a necessary condition to ensure vehicle safety. This not only requires the anti-skid performance of the newly paved asphalt pavement to meet the regulations, but also requires it to meet the regulations throughout its service life. For this reason, the upper layer of the pavement needs to have sufficient wear resistance and durability. [0003] According to its irregularity, size, distribution and function, the surface structure of asphalt pavement can be di...
