Abstract


This paper systematically studied the semi-rigid material mix design method , optimized aggregate gradation and blending material with the mechanical properties of three gray gravel than the composition, combined with the Pingdingshan climatic characteristics of the region and the material supply situation for the first time , crack performance, durability and other road performance . Theory and experiment showed that both high early strength of cement stabilized gravel reasonable ratio of three gray gravel , ash gravel crack resistance , and overall more uniform in nature , etc. , the study recommended three gray gravel ratio of the program has been in the promote the use of City road construction , to good effect ; addition, in order to enhance the primary crack resistance , for the first time in three gray gravel mixed with different types of fiber , and systematic study of its road performance ; for the first time raised the temperature of the grass-roots fatigue cracking index to judge the grassroots whether generated temperature fatigue failure .
