Embodiment Construction

[0040] In order to make it easier for those skilled in the art to understand the present invention, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings.

[0041] The invention provides a kind of asphalt pavement maintenance method, comprises the following steps:

[0042] S1. Asphalt prefabricated square blocks. Press the remaining material after the asphalt pavement is laid into a rated size square block with a hydraulic press and a mold. The length of the square block is: 300mm, the width: 300mm, and the thickness: 45mm;

[0043] S2, square plate storage, the pressed square plate is sealed and stored with a plastic film;

[0044] S3. Clean up pits and cracks, estimate the number of square plates used according to the size of pits or cracks, and dig out square trenches of appropriate size;

[0045] S4. Spray asphalt-bonded oil, evenly spray asphalt-bonded oil on the inner wall and bottom of the squar...

Abstract

The invention relates to the technical field of pavement maintenance equipment, in particular to an asphalt pavement maintenance method and a vehicle additionally-hung forward-pushing type road roller. The method comprises the following steps that S1, square plates are prefabricated through asphalt, specifically, excess materials obtained after asphalt pavement laying are pressed into the square plates with the rated size through a hydraulic machine and a mold; S2, square plate block storage; S3, pit slot and crack broken parts are cleaned; S4, spraying asphalt bonding oil; S5, preheating thesquare plate, namely heating the square plate to 60-70 DEG C by using a heating furnace; S6, pit slot crack treatment is conducted, specifically, the preheated square plate blocks are placed in a square slot, and stone particles are evenly scattered at the joints of the square plate blocks and the road surface and the joints of the square plate blocks; and S7, the square plates are compacted, andthe square plates are flattened through the road roller. The invention provides a new pavement maintenance method which can effectively utilize residual materials left after pavement repair and avoidswaste caused by stir-frying of excessive asphalt mixtures by equipment and saves resources, energy and money.

Description

technical field [0001] The invention relates to the technical field of road surface maintenance equipment, in particular to an asphalt road surface maintenance method and a vehicle-mounted front-push road roller. Background technique [0002] With the rapid development of my country's economy, highway construction is developing rapidly. Among the existing main trunk roads in my country, more than 70% are asphalt pavement. However, due to the differences in the asphalt material itself, as well as the influence of the design and construction level, the asphalt pavement often has common diseases such as cracking, oil flooding, looseness, and pits. Cars wear out, shortening the life of asphalt pavements. [0003] Therefore, asphalt pavement should be regularly and preventively repaired and maintained, and local and slight initial damage must be repaired in time. When the existing technology is faced with problems such as cracks and potholes, the usual process is: first measure...
