摘要
针对《公路沥青路面设计规范》(JTG D50-2017)新提出的低温开裂指数及其设计要求,依据目前正在使用的规范及现有研究,分析了低温开裂指数对道路路面破损状况和路面行驶性能影响,并计算了高等级沥青路面在相应的低温开裂指数设计要求下的养护成本,为进一步了解低温开裂指数、对道路进行合理评价、制定合理的养护方案提供参考。
Regarding the low temperature cracking index and the design requirements which are put forward in Specification for Design of Highway Asphalt Pavement (JTG D50-2017),the impact of low temperature cracking index on pavement surface condition and riding quality is analyzed.The pavement maintenance cost of high grade asphalt pavement under the requirements of low temperature cracking index is calculated,which is good for further understanding the low temperature cracking index and provides reference for a reasonable pavement evaluation and proper maintenance plan.
