Description
Technical Field
The invention relates to the technical field of road structure field performance detection, in particular to a high-elasticity rubber asphalt composite macadam seal three-in-one detection device.
Background
In recent years, with the rapid development of the economy of China, the transportation industry enters the rapid development era. However, municipal road construction in China starts relatively late, technical strength is relatively weak, and under the comprehensive action of traffic load and natural environment, early-stage damage phenomena such as cracks, settlement, rutting, oil spill and the like appear in advance only a few years after a road surface (particularly an asphalt road surface) is put into operation, so that the service performance of the road surface is greatly reduced. The early damage of the road surface is developed into the biggest problem in road construction in China, and maintenance and repair work is urgent and is developed into one of the important work carried out by the transportation department.
In the middle and later stages of the 90 s of the 20 th century, the advanced concept and technology of preventive maintenance are introduced from Shanghai. The preventive maintenance technology is essentially a mandatory maintenance measure, when the road surface structure has not produced diseases or the disease phenomenon just occurs, the maintenance is carried out in advance to kill the diseases in the cradle, and the initiative of maintenance is mastered so as to delay the damage of the road surface. At that time, the preventive maintenance technologies introduced in Shanghai include slurry seal, micro surfacing and the like, and now with the rapid development of science and technology, the preventive maintenance technologies are continuously updated, and a plurality of new technologies, new processes and preventive maintenance technologies of new materials are generated. The current technology of asphalt macadam seal is simple and widely used.
The high-elastic rubber asphalt macadam seal is characterized in that a layer of single-particle-size macadam is spread immediately after a base layer or a surface layer is sprayed with a layer of high-elastic rubber asphalt, a thin layer seal formed after rolling can seal fine cracks of the base layer or the surface layer, water is prevented from invading a pavement, and meanwhile, the rubber asphalt has excellent elasticity.
The high-elasticity rubber asphalt composite macadam seal layer is formed by combining a plurality of single-layer high-elasticity rubber asphalt macadam seal layers, the particle size of each layer of macadam is reduced from bottom to top in sequence, an embedded and extruded solid structure can be formed, the strength is higher, the anti-reflection crack capacity is higher, but the construction of the high-elasticity rubber asphalt composite macadam seal layer at present completely depends on construction experience, as the special structure of the high-elasticity rubber asphalt composite macadam seal layer, the water resistance, the density and the void ratio on site cannot be detected, the construction quality is not guaranteed, and a corresponding detection instrument is not provided, so that the high-elasticity rubber asphalt composite macadam seal layer site detection instrument and the site detection method are urgently needed to guide construction, and the construction quality is guaranteed.
In addition, traditional road surface field quality detecting instrument, such as boring core sampler, infiltration appearance etc. can only detect single index, can't accomplish a plurality of road surface performance index of continuous measurement, and the function is single, inefficiency to some detecting instrument still have other problems:
the core drilling sampling method is a common method for field sampling, the damage to the road surface is great, the reserved hole repairing work is complicated, the function of the road surface can be greatly influenced even if the hole is improperly processed, the method is limited to the construction process, the repairing of the high-elastic rubber asphalt composite crushed stone sealing layer is more difficult, meanwhile, after the core drilling is finished, the core sample is extremely easy to clamp in a drill bit, the core sample is difficult to take out, the integrity of the core sample can be greatly influenced even if the core sample is violently taken out, and therefore the subsequent performance experiment detection result is influenced, and the accuracy is questioned.
Meanwhile, the microwave technology is used for repairing the road surface, which has become popular in recent years, but the microwave technology is not integrated into the high and new technology in the road surface performance detection, and the microwave technology is required to be combined with the characteristics of the road surface performance detection, so that the detection efficiency of the road surface performance detection is improved.
