Description

Linkage type pavement repairing equipment and method for realizing pavement surveying and repairing by using same

Technical Field

The invention relates to the technical field of pavement repair treatment, in particular to linkage type pavement repair equipment and a method for realizing pavement surveying and repair by using the same.

Background

The asphalt pavement has high flatness and low noise, and the integral driving comfort degree 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 traffic is operated for a period of time, due to the comprehensive influence of the vehicle load, the natural environment and other factors, the road surface damage phenomenon can occur on the flat asphalt pavement, especially, the damage degree is more serious for the road surface with large throughput of some heavy-duty trucks, and the main reason is that the road surface bears heavy-duty damage for a long time due to frequent pressurization of heavy-duty load, so that the service life of the whole asphalt pavement can be seriously shortened.

The reasons for the pavement damage of the asphalt pavement are various, and the main reasons include: one is as follows: the foundation treatment is not in place, and the soil filling is not uniform; the step position of the widened roadbed is not processed in place, and the control of the thickness and the compaction degree of layered filling is neglected; cracks appear under the action of vehicle load and rain, and longitudinal cracks are generally formed in the condition; the second is that: the temperature stress effect is generated, the temperature stress effect appears on the surface with the largest temperature change rate and continues to extend downwards, if the temperature stress effect is not processed in time, the number of cracks is increased continuously, the width is further deepened, the attractiveness and the quality of the asphalt pavement are affected, and transverse cracks are generally formed under the condition; the third step is that: under the action of wheel load, the road surface can also cause large concave deformation on the surface, and both sides of the concave deformation are accompanied with bulges to cause subsidence; in addition, other causes may result in rutting, shifting, crowding, cold cracking, and other forms of failure that can affect the proper use of the pavement.

When the road surface condition is deteriorated and the service capability is reduced, 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 pavement restoration is generally divided into structural restoration and functional restoration and is used for restoring the structural bearing capacity and the service performance of the pavement, and the traditional pavement restoration is also characterized in that the surface performance and the bearing capacity of the pavement are continuously reduced along with the increase of the service life of the pavement, so that when the structural condition or the surface function of the pavement cannot meet the service requirement, the pavement is repaired in a mode of restoring or improving the service performance and additionally laying a reinforcing layer on the old pavement; the existing repairing mode is generally only simple repairing or repairing, and simple repairing and connecting of a damaged area are realized by using a simple grooving and bottom cleaning mode, the using standard can be reached in a short period after repairing and connecting, but the overall performance of the repairing mode is still very different from the strength of an integrally formed pavement, and the problems of upwrapping and secondary cracking easily occur on the connecting part of the repaired pavement.

Therefore, the company serving as a highway construction unit provides a method for realizing rapid survey and repair of the asphalt pavement and corresponding linkage type pavement repair equipment aiming at the existing repair of the damaged asphalt pavement after utilizing construction experience for many years and road maintenance professional knowledge, and is used for better solving the problems in the prior art.
