Problems solved by technology

The manual sanding method is fixed-point measurement, easy to carry, and the result is intuitive. It is suitable for the test of the depth of the asphalt road and the surface of the cement concrete road, but it is greatly affected by human factors and the speed is slow.
In order to improve the test accuracy and test efficiency, machine sanding is usually used instead of manual sanding. Machine sanding mainly uses mechanical equipment to spread the sand poured on the ground evenly. Both of the above two sanding methods have the problem of uniform sand spreading. The performance is poor, and the fine sand on the road cannot be cleaned automatically, and manual cleaning is still required, which is time-consuming and laborious

Abstract

The invention discloses an asphalt pavement performance testing and evaluation device, which comprises: a cover body; a screw rod coaxially arranged in the cover body, and a base is fixedly connected to the bottom of the screw rod; an inner cylinder body coaxially sleeved outside the screw rod; The outer cylinder is coaxially sleeved on the outside of the inner cylinder; two sand-loading cylinders are respectively fixed on both sides of the outer cylinder; two sand guide pipes, one sand-loading cylinder corresponds to a sand guide pipe ; Two sand smoothing boards, one sand draining pipe corresponds to one sand smoothing board; two dust suction plates, one sand smoothing board corresponds to one dust suction pan. The invention can realize the continuous operation of automatic road surface cleaning, automatic sand spreading and automatic road surface sand spreading, which can greatly save manpower and improve the efficiency of road surface performance testing.

Description

technical field [0001] The invention relates to the technical field of road surface testing equipment. More specifically, the present invention relates to an asphalt pavement performance testing and evaluation device. Background technique [0002] With the development of the highway industry, road grades continue to improve, there are more and more vehicles on the road, and the speed of driving is getting faster and faster, which leads to a substantial increase in traffic volume and speed, and also makes road safety issues gradually prominent; for To improve road safety, it is necessary to strictly control the quality of the road surface. Accurate and reasonable evaluation of the performance of the road surface is of great significance for the evaluation of driving safety and the formulation of road-related schemes; among them, the anti-skid performance is a particularly important performance of the road surface. one. [0003] Structure depth is one of the indicators for j...
