The value of cold recycling of asphalt mixture
(1) Economic benefits
The cost of cold recycling base (subbase and surface course) of old asphalt concrete road is mainly the cost of machinery and additives, and the labor cost is basically the same as that of other base courses. Compared with other semi-rigid base materials, the on-site cold recycling process saves the following costs: milling and transportation costs of old pavement, raw material costs of base (subbase and surface), transportation costs of raw materials, cost of shortening construction period, etc.
(2) Social and environmental benefits
Recycled asphalt mixture not only has certain economic benefits, but also indirectly has good social and environmental benefits, which can not be measured by money.
Because of paving recycled pavement, the old asphalt mixture is fully utilized, which solves the problem of environmental pollution caused by a large number of waste materials produced by Asphalt Pavement Renovation, protects the living environment of human beings, and meets the requirements of waste recycling in China's sustainable development strategy; Because of saving asphalt and gravel materials, it reduces the demand for materials, helps to protect natural resources, and eases the tension between the supply and demand of asphalt materials; Because the investment is saved and the project cost is reduced, some old asphalt pavements that could not be renovated in time can be repaired, so as to improve the road condition, improve the highway transportation capacity, reduce the wear of tires, reduce the transportation cost, reduce the possible traffic accidents, and ensure the driving comfort and safety.
This paper mainly introduces the aging mechanism of asphalt pavement, the basic principle of cold recycling technology of asphalt pavement, influencing factors, economic and environmental benefits, etc. Through the introduction of the basic technology of cold recycling of asphalt mixture, we can have a more comprehensive understanding of the basic characteristics and application advantages of this technology.
