摘要
针对乳化沥青冷再生作为路面下面层时适用公路等级的问题,拟定了9种典型的冷再生路面组合形式,运用BISAR3.0软件分析了不同厚度和基层模量的再生路面结构的路表弯沉值和疲劳寿命,结合工程实践和我国交通等级的划分,分析了不同厚度下冷再生面层适应的公路等级。
Aiming at applicable highway classification when taking emulsified asphalt cold recycling as lower course, 9 types of cold recycling pavement combining form is studied out, surfacing deflection and fatigue life of recycling pavement structure with different thickness and base modulus is analyzed through BISAR3.0 software, and in combination with engineering practice and the division of traffic classification in our country, applicable highway classification for cold recycling course with different thickness is analyzed.
