Abstract：In order to broaden the application of epoxy resin concrete in highway engineering,and provide a new way of waste tyre recycling,the mix proportion for rubber particles modified cold mix epoxy resin concrete with big void fraction was sys-tematically researched. Through orthogonal design,based on the index optimization of dynamic stability,freeze-thaw splitting strength ratio,low temperature fracture strain and flying loss before and after ultraviolet aging attenuation,this paper studied the optimal dosage of epoxy resin,the rubber particles,and carbon black. Test results show that in comprehensive consideration of the perfor-mance of high temperature,low temperature toughness,water stability and anti-ultraviolet ageing performance,suitable mix proportion for rubber particles modified cold mix epoxy resin concrete with big void fraction is:5% of epoxy resin,rubber particles substitutes 5% of fine aggregate,and 2% of carbon black content.
