【摘要】 为了明确橡胶颗粒沥青混合料的除冰雪性能,通过室内模拟试验方法,研究了橡胶颗粒掺量及分布层位、冰层厚度和温度等对橡胶颗粒沥青混合料除冰雪性能的影响.研究结果表明,橡胶颗粒越靠近混合料上表面、掺量越大、橡胶颗粒沥青混合料面层厚度越大,其除冰雪效果越好;随温度的降低和冰层厚度的增大,橡胶颗粒沥青混合料的除冰雪效果逐渐减弱.更多还原

【Abstract】 In order to ascertain the de-icing performance of crumb rubber granular asphalt mixture(CRGAM),the influence factors including the quantity and the position of crumb rubber granular,the thickness of ice layer and the temperature were studied.Results indicate that the de-icing performance of CRGAM becomes better when the quantities of crumb rubber granular and the thickness of CRGAM layer increase and the position of crumb rubber granular is closer to the surface of the mixture.更多还原
