Microwave caulking maintenance vehicle for asphalt pavement repairing

Abstract

The invention relates to a microwave caulking maintenance vehicle for asphalt pavement repairing. The microwave caulking maintenance vehicle comprises a microwave caulking device, an adjusting mechanism and an accessory chain slot milling machine; the microwave caulking device comprises a microwave heater and a power supply; the adjusting mechanism is used for adjusting positions of the microwave heater in the X-axis direction, the Y-axis direction and the Z-axis direction of the microwave maintenance vehicle; and the chain slot milling machine drives a cutting tool bit through a rotating chain to thermally cut an asphalt heating area, and the cutting depth is adjusted by adjusting a lifting oil cylinder, wherein the cutting tool bit is mounted on the chain slot milling machine. Through a microwave heating technique, the speed of viscous flowing and molecule diffusion of asphalt and an asphalt regenerating agent in asphalt concrete can be increased, compared with infrared heating, the advantages that the heating depth is large, and the temperatures of the upper part and the lower part of a material layer are uniform are achieved better, and the microwave caulking maintenance vehicle is particularly suitable for treating reflection cracks from the lower layer of the pavement; and the pavement microwave caulking vehicle sufficiently utilizes unique advantages of microwave heating in the aspect of engineering maintenance, the asphalt pavement cracks are repaired really from inside to outside, and the service life of the pavement is prolonged.

Description

technical field [0001] The invention relates to a microwave seam-filling maintenance vehicle used for asphalt pavement maintenance, and belongs to the technical field of road surface maintenance devices. Background technique [0002] Asphalt pavement has the advantages of flat and seamless surface, small driving vibration, low noise, quick opening to traffic after paving, and convenient maintenance, etc., and has been more and more widely used in high-grade highways and municipal roads. With the increase of asphalt pavement mileage and service life, the highway industry is facing increasingly serious maintenance tasks. At present, my country advocates the concept of green maintenance, requiring pavement maintenance to maximize maintenance efficiency and reduce the impact of maintenance construction on traffic capacity and traffic safety. Therefore, rapid and efficient asphalt pavement repair technology needs to be developed urgently. [0003] The existing asphalt pavement ...

AI Technical Summary

Problems solved by technology

[0003] The existing asphalt pavement generally has the following defects: 1) Asphalt is easy to age after being used for a period of time, and the underlying asphalt material is likely to be unreliable due to factors such as thermal expansion and contraction; 2) Traditional asphalt maintenance repairs are prone to produce Cracks affect the flatness of asphalt pavement; 3) Asphalt pavement is prone to water seepage in places with large gaps, which will easily cause damage to the asphalt pavement in this section and damage the beautiful city image; 4) When repairing the bottom layer of traditional asphalt pavement, it is necessary to put The asphalt in this area is excavated to cover the geotextile, and the asphalt is refilled for repair. The construction process is cumbersome, time-consuming and laborious, and the repair effect is not good.
