摘要:
通过加入高分子脂肪族多元醇中和环氧沥青中的游离顺酐,避免顺酐挥发对生产和使用环境的影响,保证了环氧沥青材料的绿色制备和使用.制备可用于粘结层与铺装层的环氧沥青材料平均拉伸强度分别达到6.8和2.4 MPa,平均断裂延伸率分别达到204.1%和292.3%.作为粘结层材料,与水泥混凝土的拉拔强度为2.0 MPa,剪切强度为2.2 MPa,与钢板的拉拔强度达到7.8 MPa,作为混合料制备的马歇尔试件最终稳定度为56.98 kN.
Abstract:
The free maleic anhydride in the preparation of the epoxy asphalt material was neutralized by introducing aliphatic polyalcohol, which avoided the effect of free maleic anhydride volatilizing on production and use environment, guaranteed the green preparation and use of the epoxy asphalt material. The average elongation ratio of epoxy asphalt used for cohesive material and paving material is respectively 204.1% and 292.3%, and the average tensile strength is respectively 6.8 MPa and 2.4 MPa. The epoxy asphalt cohesive material has a shear-strength of 2.2 MPa, a pull-off strength of 2.0 MPa with concrete and a pull-off strength of 7.8 MPa with steel. Marshell stability of the cured concrete is measured to be 56.98 kN.
