针对民用机场水泥混凝土道面接缝嵌缝材料出现的病害,通过分析其损坏原因,选取典型的4类机场水泥混凝土道面接缝嵌缝材料(硅酮类、聚氨酯类、聚硫类、聚硫氨酯类)进行基本物理特性、与接缝壁槽黏结性和耐候性3个方面的性能测试。结合试验结果及国内外接缝嵌缝材料相关技术规范及标准,根据23℃拉伸模量将材料分为高弹性模量和低弹性模量两种类型,将表干时间、锥入度、弹性恢复率、拉伸模量、低温拉伸量、定伸黏结性、抗燃油浸入性、抗热性和抗燃性定为机场水泥混凝土道面接缝嵌缝材料的性能指标,并给出各指标技术要求。 Aiming at the diseases occurred in civil airport pavement joint caulking materials, by analyzing the causes of the damage, typical four types of cement concrete pavement caulking materials (silicone, polyurethane, polysulfide, poly Thiourethane) for basic physical properties, and the seams groove adhesion and weatherability of three performance tests. According to the test results and the relevant technical specifications and standards of seam caulking materials both at home and abroad, the material is divided into two types of high elastic modulus and low elastic modulus according to the tensile modulus at 23 ° C. The dry time, cone penetration, Elastic recovery rate, tensile modulus, low-temperature stretch, elongation cohesion, anti-fuel oil penetration, heat resistance and flame resistance as the airport cement concrete pavement caulking material performance indicators, and given Specifications of the technical requirements.
