Soaking rut test accessory device and test method

Abstract

The invention discloses a soaking rut test accessory device. The soaking rut test accessory device comprises a base, handles and fixing clamping positions all made of metal materials. The handles comprise the first handle and the second handle which are symmetrically connected to the two sides of the base. The fixing clamping positions comprise the first fixing clamping position, the second fixingclamping position, the third fixing clamping position and the fourth fixing clamping position, are connected to the bottom of the base in a rectangular distribution mode and form a whole with the base and the handles, and the effect of fixing the rut plate mold is achieved. The invention also provides a corresponding test method. The device is simple in structure and convenient to operate, can measure the high-temperature rut resistance and the water damage resistance of the asphalt mixture under unconventional test conditions (water and even saline environments), and is used for testing thehigh-temperature stability and the water damage resistance of the asphalt mixture during mix proportion design; therefore, a traditional rut tester can finish quantitative evaluation of the performance of the asphalt mixture under the water immersion condition.

Description

Technical field[0001]The invention relates to the field of asphalt mixture performance testing, in particular to an auxiliary device and a test method for a water immersion rutting test.Background technique[0002]At present, more than 90% of the highways that have been built in our country use asphalt concrete pavement, but asphalt concrete pavement often suffers from various damages. Water damage is one of the most common damages, as well as other asphalt concrete pavement damage. One of the main reasons for this is the importance of studying the water damage resistance of asphalt mixtures. (Chen Haipeng, Shi Pengcheng, Gao Qiju, Shen Junan. Research on water stability and anti-rutting ability of asphalt mixture based on water-immersion rutting test[J].Highway,2016,61(03):149-154.)[0003]Asphalt mixture rutting test includes standard rutting test and water immersion rutting test. The immersion rutting test is often used to evaluate the high temperature resistance to rutting and water...

Problems solved by technology

[0004] Among the current test methods, on the one hand, the traditional standard rutting test machine cannot perform the water immersion rutting test alone; on the other hand, although the new rutting instrument can perform the water immersion test, it faces problems such as high price and low utilization rate.
