Abstract
According to the design strength grade of highway structural concrete and the strength residual during service period,the project combined with the test results of reclaimed aggregate density,crushing value,water absorption,mortar adhesion and chloride ion content in laboratory tests to develop systematic equipment for effective crushing of bulk concrete,high-quality shaping of reclaimed aggregate and rapid stripping of adhesive mortar.The classification standard of recycled aggregate was studied.Results The reclaimed aggregate of highway engineering can be classified reasonably,and the application technology of reclaimed powder material as a substitute for fly ash in foamed light soil is studied on the basis of activation.关键词
