Anti-scouring performance testing system for road base material

Abstract

The invention provides an anti-scouring performance testing system for a road base material. The anti-scouring performance testing system comprises a supporting device, a scouring device, a driving control device and a monitoring device which are fixedly arranged, the washing device comprises a washing box which is connected to the supporting device in a sliding manner, a sliding clamp is arranged in the washing box, one end in the washing box is fixedly connected with a first washing pressure head, and the other end of the washing box is fixedly connected with a second washing pressure head. A contact surface is concavely arranged at one side, in contact with a tested sample, of the second washing pressure head; the driving control device drives the washing box to do reciprocating motion; and the monitoring device is in communication connection with the first washing pressure head and the second washing pressure head at the same time. According to the invention, the washing scene of the road base material can be truly simulated, a pumping effect and flowing water washing in the road base material can be effectively and specifically realized and monitored, and the washing force can be controlled.

Description

technical field [0001] The invention relates to the field of material testing, in particular to a test system for the anti-scouring performance of road base material. Background technique [0002] The pavement of roads in our country generally suffers from the problem of seriously insufficient service life, and early pavement diseases are very common, among which the insufficient anti-scouring performance of the semi-rigid base is the main reason. When the pavement water seeps through the cracks in the pavement and stays in the semi-rigid base, the hydrodynamic pressure generated by the driving load will continuously wash away the fine materials in the base to form a slurry, which will be squeezed to the road through the cracks, causing spalling, mud pumping, and pits on the pavement. Diseases such as troughs and mesh cracks. [0003] In order to test the anti-scour performance of materials, the anti-scour test in T0860-2009 of "Test Regulations for Inorganic Binder Stable ...

AI Technical Summary

Problems solved by technology

[0006] The main purpose of the present invention is to provide a test system for the anti-scouring performance of road base materials, aiming to solve the problems in the prior art that the pumping effect is not obvious, the dynamic water scour is insufficient, the applied load cannot be adjusted, and the reality is low question
