Asphalt pavement in utilization would be affected by traffic load, climate and its own materials properties or construction faults to generate potholes, cracks, upheavals, cavity, edge failures, looseness, bleeding, waviness and ruts, which would spread to larger area and down to the road base affected by traffic shocks and bad weather conditions.
This pothole repair machine consists of dusting unit, asphalt heating unit, asphalt mixtures mixing unit, generator and other working units. It applies innovative technique in asphalt pavement maintenance to concentrate many processes in one truck, like asphalt heating, materials mixing, old materials recycling, blowing and dusting, asphalt spray, coating and so on. This machine repairs the pavement flexibly and quickly, safely and efficiently. It is likely to mix the materials on site; complete large intensity of repair at low cost at all-weather, which fulfills the requirements of quick arrival, quick repair and quick departure.
It keeps stable asphalt to aggregates ratio by means of fixed amount asphalt supply and fixed volume aggregates supply. Temperature controller accurately measures the temperature in mixing roller by the sensor and effectively controls the temperature for mixing and discharging. Truck-mounted power unit supplies all the electrical tools including the welding machine for maintenance of pavement, guard rails and other collocation facilities. This economical and practical machine shall be the optimal equipment for mechanized maintenance of high-grade roads and urban asphalt pavements.
