Abstract：Tosolvetheproblemsofsolidwastepolltionandbuildingmaterialshortage，theresourceutilizationtechnologies offour typical solid wastes in expressway constructionare explored.Thephysicochemical properties and engineering adaptabilityareanalyzedthroughlaboratorytesting，pilot-scalevalidation，andfieldverification.Theresultsshowedthatthe leaching concentration of Pb and Cd in the stabilized gold tailings met the standard，and the performance indicators of all testsections met therequirements of expresswaydesignand construction specifications.Theconclusion indicates thatthe four types of solid waste can be safely used on expressways after reasonable treatment.
