Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0030] In order to design an effective, convenient and comprehensive test device for the anti-scour performance of water-stabilized gravel base, and to propose a more reasonable evaluation index, it is necessary to develop a test device for the anti-scour performance of water-stabilized gravel base material, test Methods and evaluation indicators, in order to comprehensively evaluate the anti-scouring performance of water-stabilized gravel base materials, we put forward the following four requirements:

[0031] (1) The test device must be able to simulate the force of the vehicle load on the water-stabilized gravel base;

[0032] (2) The test device must be able to simulate the scouring effect of water on the water-stabilized gravel base;

[0033] (3) The test device must take into account temperature stress, salt erosion, and pumping action;

[0034] (4) Reasonable evaluat...

Abstract

The invention provides a programmable water-stable macadam base two-phase roll-compact washing machine. The washing machine comprises a water-stable macadam base washing control water tank, and a two-phase roll-compact washing chamber is connected with the water-stable macadam base washing control water tank; the water-stable macadam base washing control water tank provides liquid for the two-phase roll-compact washing chamber, so that experimental simulation completely accords with actual road washing conditions, and an experimental structure is closer to actual road washing. The programmablewater-stable macadam base two-phase roll-compact washing machine comprehensively takes factors such as load, solid-liquid two-phase function, temperature, permeation pressure and erosion effect intoconsideration and is more complete and scientific than a previous device.

Description

technical field [0001] The invention belongs to the technical field of performance testing of road engineering materials, and relates to a programmable water-stabilized gravel base two-phase rolling and scouring instrument. Background technique [0002] Water-stabilized macadam base has high strength, rigidity and bearing capacity, and good fatigue resistance. It is the most widely used pavement structure in my country at present. However, as the road is put into use, there are often diseases such as early cracking of the pavement and hollowing out of the slab bottom due to the insufficient anti-scouring performance of the water-stabilized macadam base pavement, which affects the use function of the road and greatly reduces the service level and quality of the pavement. The service life increases the whole life cycle cost of pavement. Therefore, it is necessary to design an effective and convenient test device for the anti-scour performance of water-stabilized gravel base. ...
