Problems solved by technology
Cold recycling technology cannot be used on high-grade highway pavement because of its poor product quality; hot-in-place recycling equipment and technology are currently imported, not only expensive, but also narrow in scope of application, and the quality of the road surface is not ideal; Type thermal regeneration is prone to secondary pollution, and the old asphalt is easily burnt and aged due to exposure to open flames, and the utilization rate of old materials is low
The above recycling technologies are difficult to meet the requirements of high-grade pavement use

The invention discloses double-roller complete processing equipment of recycled asphalt concrete. The complete processing equipment comprises a continuous double-roller recycled asphalt mixer, a new-aggregate feeding system, an old asphalt mixture feeding system, a feeding system of new asphalt and a waste-asphalt recycling agent, a powder-material feeding system, a pre-mixing device, and a finished-material lifting and storing system. According to the complete processing equipment disclosed by the invention, the new asphalt, the waste-asphalt recycling agent and powder materials are added in the pre-mixing device to be premixed so as to be uniform before entering the continuous double-roller recycled asphalt mixer. Through the technical scheme adopted by the complete processing equipment, the stirring time of the continuous double-roller recycled asphalt mixer can be shortened, and the quality of the recycled asphalt concrete is improved.
Description
technical field [0001] The invention relates to asphalt processing equipment, in particular to a double-drum recycled asphalt concrete processing complete set of equipment. Background technique [0002] Asphalt pavement has been widely used on urban and rural roads, especially high-grade highways, for its excellent performance such as smooth driving, no reflection, low noise, small dust, convenient maintenance, and little impact on traffic. However, with the prolongation of use time, various lesions will occur on the asphalt pavement under various loads, making the asphalt pavement slowly turn brittle, lose elasticity, gradually harden, appear cracks, potholes, until aging, and cracks. [0003] Asphalt pavement material recycling technology, because it can recycle asphalt concrete waste and old materials, solve the environmental pollution problem of asphalt concrete waste and old materials, and save new asphalt mixture resources, so it has good economic benefits and social b...
