Road Performance Of Low-Dose Cement And Lime Fly Ash Stabilized Aggregate

Semi-rigid base material has been used for many years in our country, but its inherentearly damage problems have not been completely resolved. Pavement diseases have seriousimpact on the pavement beauty, traffic safety and traffic comfort, so research in reducing thesemi-rigid crack, scour, anti-freezing performance is necessary. To solve the disease problemof semi-rigid base, many pavement structure types such as full soft asphalt pavement, gradedgravel soft asphalt pavement, half rigid and soft composite base asphalt pavement structurehave been used, but the asphalt pavement with semi-rigid base is still the main form of asphaltpavement structure.In this paper several determination of the test evaluation and compared with low dosageof fly ash cement stabilized macadam and low dose lime fly ash stabilized stone roadperformance. This paper adopts different cement, fly ash and lime: fly ash, the proportion oflow dose bond fly ash stabilized stone composition design and road performance analysis.Through the low dose of cement, lime fly ash stabilized macadam mechanicsperformance test were analyzed, and low dose cement, lime fly ash stabilized macadammaterial of unconfined compressive strength, splitting strength and compressive modulus ofresilience and indicators, and reference standard requirement put forward the applicable scope;Through the low dose of cement, lime fly ash stabilized macadam antifreeze coefficient andwater stability coefficient test to investigate the frost resistance and water stability; And wereused respectively to mechanical method and electrical measuring method of low dose ofcement, lime fly ash stabilized macadam drying shrinkage performance and temperatureshrinkage performance test and evaluation. Provide guidance for the application of low doseof cement, lime fly ash stabilized crashed stone semi-rigid base.
