Abstract

Asphalt cold recycling technology has many advantages, such as rapid construction, energy saving, and environmental protection. In this article, the works based on the flood control dike road repair of lower Yellow River flood control project and cold asphalt recycling technology. Combined with the current flood control dike road in Liaocheng, the old pavement rehabilitation program was designed and the program was successfully implemented. It provided a successful reference cases for application of asphalt cold recycling technology for flood control dike road repair in the lower Yellow River flood control project.

Highlights

  • Asphalt recycling technology was asphalt pavement material recycling technology, it was the entire process technology that the old asphalt pavement needed to overhaul or abandoned was added in the right amount of new aggregate, new asphalt after scarifying, recycling, crushing, screening, and re-mixed into a good road performance of recycled asphalt mix, for pavement surface or substrate

  • It was beneficial to handling of waste, energy conservation, environmental protection, which had a significant economic and social benefits

  • ĈThis project of the asphalt pavement cold recycling technology was first applied for road repairing in Shandong Yellow River flood control dike

Summary

THE PURPOSE AND SIGNIFICANCE OF ASPHALT RECYCLING TECHNOLOGY

Asphalt recycling technology was asphalt pavement material recycling technology, it was the entire process technology that the old asphalt pavement needed to overhaul or abandoned was added in the right amount of new aggregate, new asphalt after scarifying, recycling, crushing, screening, and re-mixed into a good road performance of recycled asphalt mix, for pavement surface or substrate. Could save a lot of asphalt and gravel material, saving engineering investment. It was beneficial to handling of waste, energy conservation, environmental protection, which had a significant economic and social benefits
