Description

Background of the Invention [0002] Road pavement method for prevention of pot holes [0003]

The present invention relates to a pavement method for preventing a port hole, and more particularly, to a pavement method for preventing a port hole from being generated on a packed road by preventing a vehicle accident, reducing maintenance cost for repairing a port hole, And a pavement method for preventing port holes that can extend the service life of a packed road by improving the supporting force.

Asphalt pavement and concrete pavement are generally used as road pavement, and concrete pavement is also increasing, although asphalt pavement is present at present. The settlement or breakage of pavement layer was a problem of asphalt pavement before, Deformation due to asphalt pavement is becoming a major problem due to heavy rainfall, heavy snowfall or heavy traffic, and rapid increase in traffic volume. In addition, asphalt pavement has a repair service period of about 2 years after opening the traffic, and when plastic deformation or breakage occurs, it is difficult to understand the cause of the breakage and the problem of increasing the maintenance cost is emphasized

Such asphalt is called a pot hole, which is a small hole formed on the surface of the pavement during construction. The cause of the occurrence is caused by insufficient voltage at the time of construction, poor quality of the mixture, poor drainage structure, and the like. As a repair method, it is necessary to improve the drainage structure in case of patching of defective parts, local repacking, and poor drainage.

In addition to the construction of the asphalt, the above-mentioned port hole is formed by repeating the freezing and melting of the asphalt-permeated water after the construction according to the temperature or by the corrosion by the calcium chloride, and the asphalt breaks and falls As a result, a large hole is created, and the wheels of the traveling vehicle are lost, causing a serious problem that the tire is punctured or the traveling direction is changed to cause an accident.

Recently, as disclosed in Korean Patent Application No. 10-2013-0141544, a paving method for repairing a broken port hole or a damaged portion formed on an asphalt of a road is disclosed. However, since the repair is performed after the port hole is formed, the formation of the port hole can not be fundamentally prevented, and an accident caused by the running of the vehicle after the port hole is formed can not be prevented.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
