摘要
环氧树脂改性乳化沥青具有热固性特点,固化后胶体弹性高,粘结强度明显优于一般的改性沥青。通过剪切性能和拉拔性能试验,比较分析4组不同B组分含量、不同洒布量条件下的环氧树脂改性乳化沥青与水泥混凝土板的层间粘结效果,提出了环氧树脂改性乳化沥青洒布量与抗剪强度的相关关系,以及不同B组分含量环氧树脂改性乳化沥青的最佳洒布量为1.70～1.80kg/m^2;同时,结合环氧树脂改性乳化沥青强度形成特点,提出了与之相适应的应力吸收层施工工艺要求。
The epoxy resin modified emulsified asphalt has thermosetting characteristics,and the bonding strength is obviously superior to the general modified asphalt after curing.Being based on the shear performance and pull performance test,the interlayer bonding effect between epoxy resin modified emulsified asphalt and cement concrete slab has been researched under four different conditions of B components and spraying dosage.The correlation between the amount of epoxy resin modified emulsified asphalt and the shear strength has been obtained,and the optimum spraying dosage of epoxy resin modified emulsified asphalt with different B component content is 1.70~1.80kg/m 2.Being combined with the formation characteristics of epoxy resin modified emulsified asphalt,the construction process requirement of stress absorption layer has been pointed out.
