Abstract

The invention discloses a wheel type polishing and skid-resisting all-in-one machine for complex road working conditions, relates to multifunctional pavement indoor experimental equipment integratingpavement polishing simulation and skid-resisting performance testing, and aims to solve the problems that a test piece of an existing wheel type accelerated polishing machine is uneven in polishing and an existing skid-resisting performance testing machine is low in testing speed. The wheel type polishing and anti-sliding all-in-one machine for road complex working conditions comprises a polishingmachine body, an anti-sliding performance testing machine body, a movable workbench, a working base and two workbench frames; the movable workbench slides on the working base, and the polishing machine body and the anti-sliding performance testing machine body are arranged on two working supporting frames respectively. The accelerated loading polishing test of the mixture test piece and the anti-skid performance detection test after polishing are integrally combined and matched, the machine body is free of obvious noise and vibration under the condition of high-speed rotation, a real tire andthe real mixture test piece are adopted for testing in the testing process, and high testing precision is achieved.

Description

technical field [0001] The invention belongs to the field of road engineering test equipment and mechanical design, and in particular relates to a multifunctional road surface indoor test equipment which integrates road surface polishing simulation and anti-skid performance test. Background technique [0002] The problem of traffic safety has always been a social problem of common concern to all countries in the world, and the anti-skid performance of road surfaces is one of the key factors that determine driving safety. Relevant studies have shown that road traffic accidents caused by insufficient pavement anti-skid performance account for about 30% of the total in all countries in the world, and the traffic accident rate on wet roads is much higher than that on dry roads. The anti-skid performance of new asphalt pavement can generally meet the requirements of the code, but under the combined action of traffic load and natural environment, the pavement texture continues to ...
