Abstract

The embodiment of the invention discloses a method, an apparatus and a system for detecting the compactness of asphalt pavement. The method comprises the following steps: acquiring an echo signal transmitted by a radar, wherein the echo signal is reflected waves received during the detection of the measurement points of the asphalt pavement by the radar; analyzing the echo signal to obtain the corresponding dielectric constant of every measurement point; acquiring the corresponding compactness index of every measurement point according to the dielectric constants; and acquiring the corresponding compactness of every measurement point according to the compactness indexes, and using the corresponding compactness of every measurement point as the compaction data of the asphalt pavement. The compactness index is introduced to simplify the quantitative relationship between the dielectric constant and the compactness. Compared with the prior art, the method allows workers to directly acquire the compactness data, overcomes the disadvantage of previous radar images mainly depending on accumulated experiences, and realizes the change from empirical judgment to the quantitative identification of the internal defects of the pavement structure.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radar detection, and in particular to a method, device and system for detecting compactness of asphalt pavement. Background technique [0002] The degree of compaction is the ratio of the actual density of the asphalt pavement after compaction of the asphalt mixture to the standard density of the asphalt mixture laboratory, usually expressed as a percentage. Good compaction can reduce the volume of air per unit volume of asphalt mixture, increase the proportion of solid aggregates, improve the anti-seepage performance, and maintain the road surface with high resistance under the action of vehicle load for a long time, thereby prolonging the service life of the road surface. The degree of compaction directly affects the heat resistance, crack resistance, skid resistance, durability and permeability of asphalt pavement. At present, in the industry standard of the Ministry of Transport...
