Analysis of Research Topic on Cement Cold-Recycled Base of High-Grade Highways
This review presents the difference between cement cold-recycled base and cement-stabilized new aggregate base. Old aggregate gradation is obviously beyond the prescribed limits. Due to old cement hydration products, the gradation of old mixture is not real by screening test, just called it “Fake Gradation”. The various factors of influence on pavement performances are introduced, including cement content, gradation, fine aggregates content, old material characteristic and water loss ratio. The main pavement perforamnce, such as mechanical properties, shrinkage properties and fatigue properties of cement cold-recycled mixture may not meet the requirement of high grade highways. The research topic of cement cold-recycled base is pointed out, which includes properties of old materials, the application of additives, the methods of improving pavement perforamnce and the establishment of pavement performances evaluation indexes, etc.
