The main purpose of road asphalt recycling and regeneration is regeneration. Regenerated asphalt is the process of revitalizing aged asphalt. Aging asphalt can be treated with low viscosity oil of a certain component, commonly known as a rejuvenator, or with asphalt of a certain viscosity. After a certain mixing process, the processed asphalt can be restored to its viscosity and reused on the road surface. The processed asphalt has a suitable viscosity, and the composite flowability of the asphalt is also greatly improved, resulting in corresponding improvements in its rheological properties.
The RAP series mixture plant mixing hot recycling equipment and supporting asphalt concrete mixing plant can be used for the recycling and reuse of waste asphalt concrete. By adding a high proportion of recycling agent, the recycled asphalt can be effectively recycled, reducing the cost of road maintenance and upkeep. When crushing waste asphalt in the team, its original grading characteristics cannot be destroyed. The gap of the crushing roller can be adjusted to ensure the crushing effect. The characteristics are easy to pass without lagging and low production noise. Wear resistant jaw plate embedded alloy wear-resistant material.
The recycling and reuse of asphalt pavement adopts asphalt recycling equipment, which saves raw material costs and effectively treats waste materials in the environmental protection industry. The recycling, heating, crushing, and screening of old asphalt use asphalt crushing and screening equipment. The processed asphalt, recycled asphalt, new asphalt, and other materials are re mixed in proportion before being laid on the road surface.
The asphalt concrete vibrating screening machine consists of a screening box, which is composed of layered mesh screens that fall from top to bottom. Each layer of mesh screens is equipped with a frame along the edge. There are two sliding tracks along the length of the box, which are fixed on the inner wall of the screening box. The sliding tracks are two parallel sliding plates with a frame in the middle. The outer wall of the screening box is equipped with a component that restricts the sliding of items inside the frame out of the sliding track, and the nearest flexible screen and frame are used.
The stacking and transportation of aggregates have a direct impact on the uniformity of aggregates and the stability of mineral grading, which further leads to the quality of recycled mixtures. During the processing, it is essential to first ensure the stability of the aggregate grading. Irregular transportation and stacking of aggregates are a major cause of aggregate segregation, so it is necessary to ensure that the place where aggregates are stacked is hardened, clean, and has a complete drainage system to avoid secondary pollution. In addition, when necessary, materials should be separated from each other to prevent cross contamination, and they should also be placed in rainproof sheds to avoid moisture affecting the formation of clusters.
