Study on Grade-parameter for Lime Fly-ash Stabilized Gravel

In order to build the relation between the material composition and the road use performance of the mixture,three types?five lime fly-ash stabilized gravel groups are tested,by study the relation of coarse-grade parameter comparative surface area with strength increase ratio?anti-cracking performance of stabilized lime fly-ash.The tests show that the coarse-grade parameter has close relation with strength growth rate,and the comparative surface area has close connection with anti-cracking performance,as indicated by the relation formula built.The study shows that the two parameters can be used to evaluate the performance of lime fly-ash stabilized gravel.
