What are the economic and social benefits of cold regenerator construction?
The recycling of asphalt pavement can effectively deal with the waste generated during asphalt pavement maintenance, make full use of resources and protect the environment.
(1) The cold recycling machine can recycle the asphalt in the old pavement materials and reduce the occupation of new asphalt resources by highway engineering, which is particularly important to alleviate the resource pressure of China as a large oil importer (China is also a large road asphalt importer);
(2) The sand and gravel materials of the old pavement can be recycled, and the cold recycling machine can reduce the occupation and consumption of new sand and gravel materials in highway engineering, and reduce the damage to the environment caused by sand and stone mining;
(3) Due to the non degradability of asphalt, the regeneration of old asphalt pavement by cold regenerator eliminates the direct pollution caused by discarding and landfill of old asphalt mixture and protects the ecological environment;
(4) The recycling of old asphalt pavement by cold recycling machine also has direct economic benefits. The cost of recycling old materials and processing is very low. Each recycling 1t of old asphalt recycling waste can save at least the material cost equivalent to 0.8t of new asphalt mixture. The price of cold recycling machine can greatly reduce the cost of highway engineering maintenance and reconstruction.
Key points of cold regeneration technology: the water content has a great impact on the asphalt mixture mixed with cement. When the water content is insufficient, the cement can not be fully hydrated and hydrolyzed in the mixture, can not play the stabilizing role of cement on the mixture, and affect the formation of strength. The water content tends to flow out, and the components of cement go with the water flow, resulting in the reduction of compressive strength; Excessive water content will also cause the dry shrinkage of asphalt mixture mixed with cement.
