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. Cracks are common diseases of asphalt pavements, the damages to roads are great, and particularly in winter and spring, due to the fact that rain and snow water permeate into the cracks, the road surface diseases in the crack state tend to be more serious under the action of driving load, and finally damage is caused. Therefore, in order to improve the quality of the pavement and reduce the pavement diseases, the recognition and control work of the early cracks of the asphalt pavement must be strengthened. The existing crack repairing method of asphalt road usually comprises the steps of manually cleaning cracks, filling asphalt into the cracks of the road, and then repairing the road surface, but because the cracks of the asphalt road usually form an irregular broken line type, the manual cleaning of the cracks is time-consuming and labor-consuming, and impurities such as sand and stone are difficult to effectively clean, so that the purity of the asphalt is reduced due to the impurities mixed in the asphalt, the repairing quality is greatly reduced, meanwhile, when the asphalt is filled into the cracks with longer length, the asphalt in a storage tank needs to be manually taken out and put into a filling tool for many times, the working efficiency is low, a large amount of asphalt is easy to scatter to the road surface, further the scattered asphalt needs to be collected and cleaned, meanwhile, operators are easy to cause harm to the health of the body due to the close contact of the asphalt for a long time, and the pavement after being repaired is difficult to maintain the road surface, the road surface bulge at the repairing position easily influences the driving safety.
