Description
Technical Field
The invention relates to the technical field of pavement repair, in particular to an asphalt crack pouring device for pavement repair.
Background
Asphalt pavement refers to various types of pavement that are made by incorporating into mineral materials a road asphalt material. The asphalt binder improves the capability of the paving aggregate to resist damage of traveling vehicles and natural factors to the pavement, and enables the pavement to be smooth, less in dust, impermeable and durable. Accordingly, asphalt pavement is one of the most widely used high-grade pavements in road construction. When asphalt pavement is used, cracks are one of the most frequently occurring pavement defects. The causes of the cracks can be mainly divided into two categories, namely structural damage cracks generated under the action of driving load, which are generally called load type cracks; another type of temperature crack is generated primarily due to temperature changes in the asphalt pavement, including low temperature shrinkage cracks and fatigue cracks, commonly referred to as non-load bearing cracks. In addition, because the surface layer of the asphalt pavement has strong bonding force, after cracks appear, if the cracks are diffused to form small-sized closed patterns, the cracks are easy to fall off in a block shape and appear as pits on the pavement; meanwhile, when roadbed settlement or traffic flow is too large due to deformation of an asphalt pavement roadbed and unsmooth drainage of soil cutting occurs, settlement occurs and pits are formed. After the pits appear on the road surface, the road surface around the pits is stressed too much due to the fact that wheels roll the edges of the pits, and the expansion speed of the pits is increased; and after the pits appear on the road, certain potential safety hazards also exist in road driving. In the prior art, the road surface in the pit area can only be cut and dug out, and a new asphalt mixture is refilled, so that the construction period is long, a construction enclosure needs to be arranged, the traffic passing efficiency is influenced, and the cost is higher. Based on this, the applicant proposes an asphalt filling and sealing device which reduces the influence on traffic and has low cost.
