The Adaptability Analysis of Cold Regenerated Structure Layer

The quality of the base layer materials is one of the key factors that influences pavement performance and service life. The previous research and experiment results have preliminarily proved that cool regenerated materials have good road-applied properties, and verified the main technical characteristics of preliminary analysis results of cement cold regenerated. Based on experimental results and cement strength standard, road performance cold regenerated aggregates and cold regenerated lime treated soil is analyzed in this paper. The results show that the performance of cement cold regenerated materials meets the requirements. Cement cold regenerated aggregates can be used as Grade 2nd and below Grade 2nd road. Under appropriate conditions, cement cold regenerated aggregates can also be used for freeway base; Cement cold regenerated lime treated soil can be used as subbase Grade 2nd and Grade 2nd below road.
