A device and method for detecting the effect of road surface compaction

Abstract

A device and a method for detecting the road surface compaction effect are provided. The device comprises a fiber bragg grating demodulator, a pressure sensor for detecting the pressure of a road surface, and a displacement sensor for detecting the thickness of the road surface, wherein the pressure sensor, the displacement sensor and the fiber bragg grating demodulator are connected. According to the invention, the principle is simple, the operation is convenient, the detection is accurate and rapid, and objective and efficient detection is implemented. The reliability and the detecting reliability are good, the manufacturing cost is low, the energy consumption is low, the scope of application is wide, the practical value is high, and the detecting device is convenient to use and maintain. The detecting method is simple and convenient, the detecting process is simple, the detecting time is short, the detecting is not affected by the outside environment, the road surface compaction effect can be rapidly and accurately detected to provide a reliable basis for the reasonable detection and construction, and the defects that the consumed time is long, the operation process is complex and the detection is largely affected by the outside environment during the detection of the road surface through a drilled core method in the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of road detection and construction, and in particular relates to a device and method for detecting the compaction effect of a road surface. Background technique [0002] The commonly used method for testing the compactness of pavement in my country is to drill core samples, and then measure the density of the core samples according to the experimental specifications, and express the compactness by the ratio of the measured density to the theoretical maximum density. The pavement thickness is detected by the core drilling method, which destroys the original pavement structure. Although the drill holes produced after core sampling can be filled with the same kind of mixture, the pavement damage caused by the drill hole position is still the most prone to disease on the pavement. weakness. However, the detection speed of drill core is slow, and it is easy to cause danger after the traffic is opened. The drill ...

Problems solved by technology

The pavement thickness is detected by the core drilling method, which destroys the original pavement structure. Although the drill holes produced after core sampling can be filled with the same kind of mixture, the pavement damage caused by the drill hole position is still the most prone to disease on the pavement. weakness

However, the detection speed of drill core is slow, and it is easy to cause danger after the traffic is opened. The drill core sampling method is a kind of destructive detection, and the drill core detection can only be carried out after the compaction is completed, and the compaction cannot be detected in real time during the compaction process. Real control, time-consuming, complicated operation process, greatly affected by the outside world
