Multifunctional positively-agitating type asphalt pavement maintenance vehicle

Abstract

The invention discloses a multifunctional forced stirring asphalt pavement maintenance vehicle; wherein, a generator set, an asphalt box and an asphalt measure and feeding device, a mineral aggregate lifting device, a burner, a mineral aggregate drying and heating unit, an asphalt concrete forced stirring device, a mineral powder weighting and conveying device, a dust remover, an electric-controldevice and an accessories device are arranged in the front of the chassis of the automobile or trailer; the mineral aggregate lifting device is fixedly arranged in front of or behind the mineral aggregate drying and heating unit; the mineral powder weighting and conveying device is arranged in parallel with a side of the asphalt concrete forced stirring device; the asphalt concrete forced stirring device and the mineral powder weighting and conveying device are added and the mineral aggregate lifting device is fixedly arranged in front of or behind the mineral aggregate drying and heating unit, compared with the prior art. The multifunctional forced stirring asphalt pavement maintenance vehicle has the advantages of resolving the prior roller type stirring asphalt concrete drawbacks of stirring unevenly of asphalt and mineral aggregate, unsatisfying the requirements of stirring, unevenly coated material, long stirring time, no initial drying and low work efficiency, and being suitablefor maintenance of a plurality of highway asphalt pavements.

Description

technical field [0001] The invention relates to an asphalt pavement maintenance vehicle, in particular to adding asphalt concrete forced stirring device, mineral powder weighing and conveying device on the chassis of the car or trailer, and fixing the mineral material lifting device to the front or back of the mineral material drying and heating device Multifunctional forced mixing asphalt pavement maintenance vehicle. Background technique [0002] With the acceleration of domestic infrastructure construction, the mileage of expressways and high-grade highways continues to increase, and the quality of road maintenance is also improving. However, the existing maintenance equipment, especially asphalt pavement maintenance vehicles, cannot provide high-quality asphalt concrete. It is used for road maintenance. For example, the compactness of asphalt concrete is also required to be high. Currently, asphalt concrete is mixed by drum type, and the asphalt concrete is mixed in the ...

[0002] With the acceleration of domestic infrastructure construction, the mileage of expressways and high-grade highways continues to increase, and the quality of road maintenance is also improving. However, the existing maintenance equipment, especially asphalt pavement maintenance vehicles, cannot provide high-quality asphalt concrete. It is used for road maintenance. For example, high requirements are put forward for the compactness of asphalt concrete. Currently, asphalt concrete is mixed by drum type mixing, and asphalt concrete is mixed in a self-falling throwing mixing state.

This mixing method leads to uneven mixing of asphalt and mineral materials, which is prone to flowering. At the same time, no measures are taken to affect the compactness of asphalt concrete. damage, and this mixing method takes a long time to mix, the mixing quality is poor, and the work efficiency is low
