Taking an asphalt concrete pavement as an example, the pavement sequentially includes an asphalt concrete upper surface layer, a first adhesive layer, an asphalt concrete middle layer, a second adhesive layer, an asphalt concrete lower surface layer, an adhesive waterproof layer and a base layer from top to bottom, and is characterized in that at least one metal wire is longitudinally paved on the bottom faces of the asphalt concrete lower surface layer, the asphalt concrete middle layer and the asphalt concrete upper surface layer, and the metal wires paved in the layers are staggered with one another.
Description
Technical field
The utility model relates to the road quality detection range, particularly a kind of road structure of being convenient to ground penetrating radar detection thickness.
Background technology
In the highway engineering quality check evaluation criterion, the thickness of the planeness of road crust, deflection value and road surface structare layer is listed in the important indicator of estimating high-grade highway flexible pavement quality, and road surface thickness is the most important in all index.How road pavement thickness index is carried out fast, is objectively detected and estimates, and is the problem that construction department and quality management department are paid close attention to for a long time always.
In the art, to the road surface thickness detection and the evaluation of relevant road, traditional method is unbearable sampling method, and existing method is that the ground penetrating radar detection technique is in conjunction with infiltrating sampling method.Though unbearable sampling method has intuitively, reliable characteristics, but its limitation is also arranged, as the damage road surface, representativeness is poor, efficient is low, cost is high.Detect with unbearable sampling and to compare, outstanding features such as that the radar monitoring technology has is harmless, efficient, high accuracy, and also its result of detection can be eliminated a peephole view of drill hole sampling.In addition, the detectivity of ground penetrating radar allows to reach below the surface layer, in order to estimate subgrade stability in advance and to find various diseases in the roadbed.So the ground penetrating radar detection technique is well used.Yet ground penetrating radar detects the thickness or the degree of depth of road to be determined according to velocity of wave, and being dielectric constant by material, calculates in velocity of wave, the dielectric constant of surface layer depends on the compactness of bitumen layer again, the dielectric constant of basic unit mainly depends on the humidity of material again, existing dielectric constant is to determine in conjunction with the laboratory test of unbearable sampling, so existing ground penetrating radar detection method itself just has limitation, but also thoroughly do not break away from the breakage on road surface.The influence of the imperfection of road self construction and other factors in addition, it is bigger to cause ground penetrating radar to detect error, and rain later or the road surface should not detect when moist cause that ground penetrating radar detects the time sex-limited.Simultaneously because the influence of the factors such as imperfection of the inhomogeneities of layers of material, interlayer combination causes Coherent Noise in GPR Record collection and processing to have very big complexity.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of road structure that ground penetrating radar detects thickness of being convenient to, can detect the structural parameters of its thickness and analysis road more convenient by ground penetrating radar, exactly, for quality control, the maintenance of pavement engineering provides detailed data, thereby the saving testing cost is increased work efficiency.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind ofly be convenient to the road structure that ground penetrating radar detects thickness, it is characterized in that, vertically lay at least one wire along the bottom surface of each layer of road structure, the wire of each layer laying staggers mutually.
Further characteristics of the present utility model are:
(1) described road structure is the asphalt concrete pavement structure, the asphalt concrete pavement structure comprises in bituminous concrete upper layer, first tack coat, the bituminous concrete surface layer under surface layer, second tack coat, the bituminous concrete, bonding waterproofing course, basic unit from top to bottom successively, respectively under bituminous concrete in surface layer, the bituminous concrete bottom surface of surface layer, bituminous concrete upper layer longitudinally lay at least one wire, the wire of each layer laying staggers mutually.
(2) described road structure is the cement concrete pavement structure of conventional concrete panels.
(3) wire of described vertical laying is parallel two.
(4) described wire is an iron wire.
Adopt road structure of the present utility model, for road maintenance maintenance with when the quality monitoring of building road, because dielectric constant wiry is constant, and wire even thickness, be close to deck, because wire has good reflection effect to electromagnetic wave, not only made things convenient for the valid data collection of ground penetrating radar in addition, and the work of the post analysis treatment system of ground penetrating radar exploration also oversimplifies, and also avoided the breakage of unbearable sample analysis data to road simultaneously.The received back wave of ground penetrating radar has effective representativeness of road structure and quality after increasing wire, and then can know the quality condition of pavement engineering comprehensively.
