Highway asphalt pavement multifunctional test detection system

Abstract

The invention discloses a highway asphalt pavement multifunctional test detection system, which comprises annular test pavement, a test trolley, a test control system, a pavement detection system and a heat insulation wall plate, wherein the heat insulation wall plate is arranged on the outer periphery of the annular test pavement in a surrounding way; a sealed test space is defined; an annular guide rail is arranged at the inner side of the annular test pavement; the test control system is used for controlling the test trolley, a test temperature control device, a test humidity control device and an environment simulation device; the environment simulation device comprises a rainfall simulation device and an ultraviolet ray irradiation device; the pavement detection system is used for detecting the pavement stress and deformation condition in different test environments and at different test parameters. The test trolley with the same structure as the conventional vehicle, the annular test pavement identical to the existing highway pavement structure is laid in a matched way; the test trolley walks on the annular test pavement; the milling state of the running vehicle on the pavement can be sufficiently simulated; the structure is simple; the cost is low.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement testing, in particular to a multifunctional testing and detection system for highway asphalt pavement. Background technique [0002] With the rapid development of my country's economy, the construction of highway transportation infrastructure has also achieved leapfrog development. In the pavement structure of my country's highways, asphalt pavement occupies a very important position, especially high-grade roads have accounted for about 90%. In 2005, the "five vertical and seven horizontal" national highway trunk line system was fully connected. By the end of 2016, the total mileage of my country's highways had reached 4.693 million kilometers. The proportion of semi-rigid base asphalt concrete pavement in the completed expressway is as high as 3∕4. [0003] The increase of highway traffic volume and the increase of axle load put forward a severe test to the asphalt pavement. The desig...

Problems solved by technology

Imported equipment, expensive, high energy consumption, inconvenient maintenance

Moreover, most of these equipment adopt the rolling method of a single driving wheel set or a single driven wheel set, which is inconsistent with the joint rolling of the driving wheel set and driven wheel set of the actual vehicle. The accuracy of the test data is poor, and the cycle of road surface diseases cannot be accurately predicted.
