Problems solved by technology

[0005] The purpose of the present invention is to provide a hoop structure for asphalt mixture, which can fix the position of the aggregate through the hoop, restrict the relative movement of the aggregate, stifle the chance of crack generation and development, and can fundamentally solve the problems of cracks, pits, etc. The production of asphalt pavement prolongs the service life of asphalt pavement, reduces the cost of pavement maintenance, and changes the current situation that the existing pavement is easily damaged and often maintained

Abstract

The invention discloses an asphalt mixed material hoop structure and a construction method thereof. The hoop structure comprises a plurality layers of hoop plates which are mutually fixed in an overlapped manner; through holes are uniformly formed in the hoop plates; the through holes are filled with the asphalt mixed material. By fixing the position of aggregate through hoops, constraining relative movement of the aggregate and inhibiting generation and development opportunities of cracks, problems of cracks, pits and the like can be fundamentally solved, the service life of an asphalt pavement can be prolonged, the pavement repairing cost can be reduced, and situations that a conventional pavement is easily damaged and frequently repaired can be alleviated.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement construction, in particular to an asphalt mixture hoop structure and a construction method thereof. Background technique [0002] In highway construction, asphalt concrete pavement, as a seamless continuous pavement, has many advantages such as good surface smoothness, comfortable driving, wear resistance, small vibration, low noise, short construction period, simple maintenance and repair, suitable for phased construction, etc. , has been more and more widely used. However, with the rapid increase in traffic volume, large-scale vehicles, channelized loads, and severe overloading have emerged one after another. The asphalt concrete pavement is facing severe challenges, and early diseases such as rutting, cracking, and potholes have also occurred. [0003] In order to solve the above problems, scientific and technological workers have used methods such as asphalt modification and fiber re...
