Study on Performance of Organic Palygorskite Modified Asphalt Mixture
摘要
Abstract
The influence of organic palygorskite on the road performance of asphalt mixture were systematically analyzed by Marshall stability test,high temperature rutting test,low temperature trabecular bending test,immersion Marshall test and freeze-thaw splitting test.The low carbon emission reduction performance of organic palygorskite modified asphalt mixture were systematically studied by asphalt smoke test and exhaust gas analysis test.The results showed that,with the increase of organic palygorskite content,the stability of modified asphalt mixture increased by 23.6％,the dynamic stability increased by 30.0％,the critical value of strain energy density increased by 31.9％,the residual stability increased by 7.33％,and the freeze-thaw splitting residual strength increased by 5.85％,indicating that the road performance of asphalt mixture can be improved by organic palygorskite powder.The asphalt smoke concentration decreased by 50％,the CO concentration decreased by 40％,and the NOx concentration decreased by 20％,in the whole mixing process of modified asphalt mixture.The results the organic palygorskite modified asphalt mixture has excellent low-carbon emission reduction efficiency with 20％content of organic palygorskite.关键词
