Ash macadam mixture as a semi- rigid base material , with its excellent road in Pavement Performance has been widely used. However , in the design and construction process , due to improper design methods and materials selection , as well as the shortcomings of the evaluation specification single , making this material does not play its due advantage . In this paper, the analysis and summary of flyash gravel road performance research status , preferably seven kinds are more representative of the aggregate gradation program , and then according to the theory of gradation , Bailey method on seven different level with the analysis, evaluation ; the two gray gravel design method for high-performance amended , and in accordance with the design of the design method seven ash macadam mixture road performance in a more systematic theoretical research and test analysis . According to the gray system theory to study the maximum particle diameter D , the maximum dry density p, the optimum moisture content ω ,31.5-37 .5 mm aggregate content , different size aggregate porosity ( 2.36mm , 4.75mm, 9.5mm , 19.0 four kinds mm particle size) , ash binder content and other factors to road performance of primary and secondary relationship . Ash gravel material shear strength theory to explore and study , flyash macadam mixture triaxial test , triaxial test stress - strain curve ; article also study the shear shear strength index c , φ main factors and their primary and secondary relationship , and triaxial test shear modulus indicators . In this paper, on the basis of the indoor studies , combined with research , paving a test road . The test results verify the correctness of the indoor studies . The purpose of this dissertation ash crushed stone Base design and construction are important guiding significance .
