Problems solved by technology

When disputes arise, the thickness data detected by radar cannot be used as the basis for project quality assessment, which seriously restricts the development of this non-destructive testing technology
[0009] (2) Unable to layer test
As mentioned earlier, due to the same properties such as the dielectric constant of different asphalt layers, it is impossible to distinguish and detect the thickness of each layer of asphalt layer through radar detection

Abstract

An emulsified asphalt binder course for radar determination of surface thickness. The weight ratio of the bonding layer is: 2.5 parts of metal powder, 100 parts of emulsified asphalt, 0.7 part of anti-stripping agent, 0.15 part of antioxidant, and 0.12 part of coupling agent. The emulsified asphalt bonding layer is laid on the semi-rigid base layer and between the asphalt layers. The bonding layer has high bonding strength, which can make the asphalt pavement structure layer into a whole, improve its service life, and can significantly enhance the electromagnetic wave signal of radar thickness measurement , improve the test accuracy, and can realize the layered detection of the thickness of the asphalt layer, and can be widely used in the construction quality control of urban roads, airport roads and highways.

Description

technical field [0001] The invention belongs to the technical field of pavements such as urban roads, airport roads and highways, and in particular relates to an emulsified asphalt bonding layer used for measuring the thickness of a surface layer by radar. Background technique [0002] With the rapid development of highway construction, the mileage of expressways in my country has exceeded 130,000 kilometers, and the total mileage of highways of all levels has reached more than 4 million kilometers, of which more than 95% are asphalt pavement structures. Strengthening project quality control is an important means to ensure the service life of asphalt pavement. The basic basis of quality control is test data. Therefore, continuously improving the test level and increasing the test frequency are effective ways to improve project quality. For the surface layer structure of asphalt pavement, the thickness is an important indicator of pavement quality control, which is directly r...
