Description

Asphalt pavement crack repairing vehicle

Technical Field

The utility model belongs to the road building mechanical equipment, concretely relates to bituminous paving crack repairing vehicle.

Background

The asphalt pavement cracks are one of main diseases of the pavement, if the cracks are not maintained and treated in time, surface water is soaked into a pavement base layer to cause the base layer to be soft and reduce the strength, and the pavement is damaged quickly after repeated rolling by a vehicle, so that the driving comfort is influenced, and the maintenance cost is increased.

In the traditional asphalt pavement crack filling, containers such as an iron bucket, a kettle and the like are adopted for filling asphalt, the containers are manually held to fill along the crack, then stone is manually spread to cover the asphalt, and the problems of uneven asphalt consumption, incapability of filling all cracks and the like can be caused under the influence of weather, wind power and operation proficiency; the road maintenance standard requires that the crack pouring of the asphalt pavement is finished before the rainy season, the rainy season generally starts about 6 months according to the climatic characteristics of the northern part of China, so the crack repairing of the asphalt pavement basically starts the asphalt crack pouring at the beginning of 4 months, when the traditional crack pouring mode is applied, because the air temperature is low during construction, after the asphalt is taken out from an asphalt spreading vehicle by adopting a container (such as a sharp-mouth iron kettle), the asphalt is cooled quickly, the fluidity of the asphalt is reduced during pouring, the crack pouring asphalt can not be filled, the crack pouring material can not be completely embedded into the asphalt, after the air temperature is increased, the asphalt is taken away by a running wheel, the secondary appearance of the crack and the environmental pollution are caused, and in particular, when the hot asphalt is poured, and the wind power is high, the scalding risk exists.
