Abstract


This thesis focuses on the rapid development of transportation infrastructure , the lack of traditional road construction materials highway construction requires a large amount of purchased materials caused by the high cost and lack of construction funds the contradictions bound to become increasingly prominent . In order to study the alternative technologies , alternative to traditional road construction materials , synthetic material , and the papers to inexhaustible inexhaustible wealth of the soil resources rely on the the composite consolidated soil as road base materials subject . Compressive mechanical properties of the composite consolidated soil road base materials through the test , flexural mechanical properties, frost resistance , water stability and low temperature shrinkage performance analysis study concluded . Due to the soil stabilizer consolidation role , not only can reduce the amount of lime and cement stabilizer with earth instead of the traditional road construction materials such as sand, stone ; mechanical properties of the composite consolidated soil road base materials , frost resistance , water stability and low temperature shrinkage performance indicators and cement stabilized gravel , two gray gravel and lime soil or other base material roughly ; the consolidated several tests , the best ratio of the composite consolidated soil road base materials for stable materials : soil the curing the agent = six ninety-four 0.02% ; 100m3 composite consolidated soil pavement base materials and cement stabilized gravel , two gray gravel cost analysis point of view , has significant economic benefits .
