Research and Experiment on the Road Performance of Scoria (Volcanic Ash)
According to the tests and researches, this paper combine the constructing condition of scoria (volcanic ash) subgrade and lime-volcanic ash gradation macadam subgrade and the result of investigation and detection after the test section is completed, the physicochemical property, engineering property, compaction mechanism and performance, formation mechanism and increasing rule of strength of scoria (volcanic ash) and lime-volcanic ash are systematically analyzed, propose the construction technology and detection method of scoria (volcanic ash) subgrade and lime-volcanic ash gradation macadam subgrade, provide technical support and theoretical basis for application of scoria (volcanic ash) on road construction.
