Warm Mix Asphalt Pavement Recycling Techonlyg And Engineering Applications In Tianbei Road

In recent years,the green environmental protection has become the theme of the development of the times,and the concept of energy conservation and emission reduction and low-carbon environmental protection in various fields is deeply embedded in the development strategy of the enterprise,and this concept is also adhered to in the field of road construction in China.With the development of our country’s road construction technology,the asphalt mixture warm-mixing technology has become a new technology of asphalt pavement.The technology has the advantages of high laying efficiency,high recovery rate of old materials and the like,and gradually occupies the green road construction market in China.The warm mix reclaimed technology is combining the warm mix asphalt technology and the hot mix plant recycling technology.Through taking viscosity drag reduction agent,new mineral material,new asphalt and RAP In about 20-30 ℃lower than thermal regeneration temperature for mixing regeneration.Under the premise of without sacrificing pavement quality,can achieve the effect of both Improving the utilization ratio of regeneration of old material,and reducing production construction temperature,the mixing proportion of recycled material regeneration can be increased up to 45%-50%,and obviously reduce the temperature of the old mixture heating,mixture production and construction,at the same time ensure the good performance of recycled asphalt mixture.This technology integrates the advantages of warm mix technology and heat regeneration technology,break through the bottleneck of the low utilization rate of old materials of hot mix plant recycling technology.Meanwhile,it fused the old asphalt mixture recycling technology,under the support of a variety of excellent technology of the warm mix technology.In order to implement the " Human traffic,science and technology traffic,green traffic" concept,In the aspect of road construction,the present high and new technology should be used to develop green construction projects.To this end,this paper will study the construction design,raw material preparation,process improvement and completion acceptance of the asphalt concrete warm-mix technology through the research of warm-mix regeneration technology.The present situation of hot-mix recycled asphalt concrete technology is summarized.it is judged at present that the technology is superior and inferior in road laying,technical performance,quality control,and technical reliability,so that the technology can be used in the course of road construction in the future,A large number of applications are used for theoretical research and reference.
