摘要
为了研究高模量沥青试验段性能,选择几种高模量沥青,通过有限元力学分析建立高模量与厚度等效关系,并通过各指标综合评价试验段性能。研究表明:基于弯沉等效进行路面厚度换算,采用橡胶沥青相当于SBS改性沥青路面厚度提高1.62 cm。橡胶沥青模量指标满足高劲度模量混合料技术要求。
In order to study the performance of high modulus asphalt test section,several high modulus asphalts were selected in this paper.The equivalent relationship between high modulus and thickness was established by finite element mechanical analysis.And comprehensively evaluate the performance of the test section through various indicators.The research shows that the thickness of the pavement is equivalent to the thickness of the SBS modified asphalt pavement by 1.62 cm.The modulus index of the rubber asphalt HMAC20 mixture meets the technical requirements of the high-stiffness modulus mixture.
