An asphalt mixture surface structure depth tester and its test method

Abstract

The invention discloses an asphalt mixture surface structure depth tester and a testing method thereof, comprising a supporting part, a sand dumping part, a paving part, a photographing part, a cleaning part, a main controller and a supporting part; the supporting part includes a bottom plate , two support frames and a loading board, the paving components include a fixed column, a push plate, a telescopic rod and a push plate handle, the sand dumping components include a sand storage cylinder, a calibration pipe and a slide, and the main controller includes Blower adjustment switch, paving control knob, camera switch, display screen, and normal machine master switch. The invention can quickly measure the depth of the asphalt mixture surface structure, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of road engineering test equipment, and relates to a depth tester and a test method thereof, in particular to a depth tester for the surface structure of asphalt mixture and a test method thereof. Background technique [0002] At present, more and more asphalt pavements have many early diseases, and the anti-skid ability of the road is very limited. In the case of rainy days and excessive speed, various traffic accidents are easily caused due to insufficient anti-skid ability. affect road safety. As an important aspect of road skid resistance, it is very important to ensure that the road surface has an appropriate structural depth. However, when designing the proportion of asphalt mixture, we often only pay attention to the strength of the mixture, but ignore the depth of the surface structure of the mixture, which is closely related to road safety. Although the current standard has a corresponding test method for t...

However, when designing asphalt mixture proportions, we often only pay attention to the strength of the mixture, but ignore the depth of the surface structure of the mixture, which is closely related to road safety.

Although the current standard has a corresponding test method for the depth of the surface structure of the asphalt mixture, we still need to see that the current method has many human factors and large test errors, and a convincing evaluation method for the surface structure depth of asphalt mixture is still needed. keep exploring
