摘要
沥青碎石基层因其具有防止反射裂缝和提高沥青路面高温稳定性等优点,具有较大的推广价值。结合广东佛开高速公路大修工程ATB-25混合料设计和施工,分析其路用性能,并提出了合理的摊铺和碾压技术,有效地避免了集料的离析,提高了压实度,保证了施工质量和进度。
ATB-25 has great promotional value because of its prevention of reflection cracks and improving the high temperature stability of asphalt pavement.In this paper,based on the ATB-25 mixture design and construction of the revamp of Guangdong Fokai expressway,the road performance is analyzed,and the reasonable paving and rolling technology are put forward.They can effectively avoid aggregate segregation,increase compaction to ensure construction quality and progress.
