Hot regeneration refers to the asphalt pavement in the process of regeneration of the old materials need to be heated, and as required to add other renewable additives, and then carry out other regeneration process. Thermal regeneration can be divided into hot mix regeneration and in situ heat regeneration. (Recycled) asphalt pavement material (RAP) to the asphalt mixing plant (field, station), broken, sieved, with a certain proportion of new aggregate, new asphalt, renewable agent (if necessary) The technology of making pavement with hot mix and mixing. Local thermal regeneration technology has been considered a revolution in the road industry; However, the practice has proved that the field of thermal regeneration there are many limitations: the processing of small thickness; can not effectively adjust the mix of recycled mixture, the main For the surface regeneration; uneven thickness of the road surface or the quality of the road changes in the road is difficult to guarantee the quality requirements. China's asphalt pavement disease, mainly water damage, cracks and other structural damage, the surface treatment is difficult to solve these problems, so the geothermal regeneration equipment should not be promoted in China.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery

In the case of on-site thermal regeneration, the asphalt pavement is heated, milled, mixed with a certain amount of new asphalt and other regenerators, etc., and then hot mixing, paving, rolling and other processes, so the unit is complex and complex How many units can be combined to operate, the first phase of the investment equipment is also larger. In situ thermal regeneration equipment can be divided into two kinds of re-regeneration, resurfacing and regeneration. China's asphalt pavement regeneration equipment development is still in its infancy, the road crushing with the milling machine has a number of companies in the production, renewable mixing equipment has also been the product supply, milling machine and local cold regenerator is mainly imported In some areas, some areas have also purchased in situ thermal regeneration units. Whether the local thermal regeneration unit is suitable for China's road, still need to conduct research and testing, because the type of equipment costs are high, not blind development. Asphalt pavement regeneration equipment development and purchase should be combined with the regeneration process to be considered in order to get the best results.
