Background
The asphalt pavement has high flatness and low noise, and the overall travelling comfort is higher than that of a pure concrete pavement, so that the asphalt pavement is widely applied to highway engineering construction. However, after the engineering vehicle is operated for a period of time, the road surface damage phenomenon can occur to the flat asphalt road surface due to the comprehensive influence of factors such as vehicle load, natural environment and the like, and especially the damage degree is more serious for some road surfaces with larger throughput of heavy load trucks, the reason is mainly that the road surface is subjected to heavy load damage for a long time due to frequent pressure application of heavy load, so that the service life of the whole asphalt road surface can be seriously shortened.
The reasons for pavement damage of asphalt pavement are various, and the main reasons for pavement damage include: one is: the foundation is not treated in place, and the soil filling is uneven; the step positions of the roadbed are not properly processed, and the thickness and compactness of layered filling are ignored to be controlled; cracks appear under the load of the vehicle and under the action of rain, in which case longitudinal cracks are generally formed; and the second is: the temperature stress effect is generated, the temperature stress effect is generated on the surface with the largest temperature change rate, and the surface continues to extend downwards, if the temperature stress effect is not timely processed, the number of cracks is continuously increased, the width is further deepened, the appearance and the quality of the asphalt pavement are affected, and transverse cracks are generally formed under the condition; thirdly, it is: the pavement can also deform with larger depressions generated on the surface under the action of the wheel load, and the depressions deform with the bulge on two sides to cause sinking; in addition, other causes may lead to breakage forms such as ruts, shifts, congestion, low temperature cracks, etc., which may affect the proper use of the pavement.
When the above-mentioned condition of the road surface is deteriorated and the service ability is lowered, effective technical measures must be taken to repair the road surface in order to ensure the normal and efficient use of the road surface.
At present, the traditional road surface repair is generally divided into structural repair and functional repair, which are used for recovering the bearing capacity of a road surface structure and the service performance of the road surface, and the repair is carried out in a mode of recovering or improving the service performance of the road surface and paving a reinforcing layer on an old road surface when the structural condition or the surface function of the road surface can not meet the service requirement due to the fact that the surface performance and the bearing capacity of the road surface are continuously reduced along with the increase of the service life; the existing repairing mode generally only adopts simple repairing or repairing, realizes simple repairing connection of a damaged area by utilizing a simple grooving and bottom cleaning mode, can reach the use standard in a short period after repairing connection, but has a great difference in overall performance relative to the strength of an integrally formed pavement, and the joint part of the repaired pavement is easy to have the problems of congestion and secondary cracking.
