Industrial construction method of "square hole and round patch" on asphalt concrete pavement

Abstract

The invention discloses ''round filling of square holes'' industrialized construction method for asphalt concrete pavements. The ''round filling of square hole'' industrialized construction method comprises the following steps: 1) detecting road conditions through adoption of a road condition rapid detection system, and collecting road condition data; 2) carrying out simulated repair of detected pavement pothole diseases through use of a computer, with a repair plan in accordance with the principles of ''round filling of square holes ''and ''large filling of small holes'', and diameter and depth of a grooving round hole at a disease place being set according to set modulus; 3) according to the set modulus of the step 2), prefabricating, in a factory, asphalt concrete prefabricated blocks to store in a warehouse for standby application at any time; and 4) getting an asphalt concrete prefabricated block needed for a construction scheme, from the warehouse, equipping grooving equipment with drill bits with a variety of modulus needed for the construction plan, and carrying out one by one repairing of disease potholes according to the pre-decided repair plan and along the direction of a road. The ''round filling of square holes'' industrialized construction method has the advantages of simple on-site construction processes, short operation time and rapid opening to traffic.

Description

Technical field: [0001] The invention relates to an industrialized construction method for "square hole and round fill" of asphalt concrete pavement. Background technique: [0002] Potholes appearing on asphalt concrete pavement is a common disease. Timely, fast and high-quality repair of holes is the key point of road maintenance. According to the "Technical Specifications for Maintenance of Highway Asphalt Pavement" promulgated by the Ministry of Communications, the repair of potholes on high-speed asphalt pavements must be filled with "round holes and square holes" and "slant holes are corrected". With this construction method, no matter whether it is repaired with hot mix asphalt, repaired with cold mix asphalt or prefabricated, it is impossible to achieve industrialized construction. [0003] The current process basically relies on personal experience to judge the operation, and the construction quality depends on the operation level of the operator. Invention conten...

Problems solved by technology

With this construction method, whether it is hot-mix asphalt repair, cold-mix asphalt repair or prefabricated assembly, industrial construction cannot be achieved.

[0003] The current process basically relies on personal experience to judge the operation, and the construction quality depends on the operator's operating level. There are disadvantages such as cumbersome repairing procedures, long working hours, great influence of weather conditions, and low repairing quality.
