Embodiment Construction

[0033]The present invention will be further described in detail below with reference to the drawings and examples.

[0034]SeeFigure 1-Figure 7This embodiment provides an auxiliary device for water immersion rutting test, including a base 1, a handle and a fixed card position. The material is made of metal such as stainless steel. The metal material does not physically interact with the salt solution at a temperature of -20°C to 500°C. chemical reaction.

[0035]The base 1 is provided with a first groove, the base wall is 150mm high and 15mm thick, and the base bottom thickness is 15mm.

[0036]The handle includes a first handle 201 and a second handle 202, which are symmetrically connected to both sides of the base, and play the role of moving or lifting the entire device, so that the device can be installed on the rutting tester.

[0037]The fixed card positions include a first fixed card position 301, a second fixed card position 302, a third fixed card position 303, and a fourth fixed card ...

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...
