摘要
某沥青混凝土路面出现提前开裂工程事故,通过现场取样进行了抽提试验,经对比分析各相关因素后,得出沥青用量(油石比)偏低是造成沥青混凝土路面提前开裂的主要诱因之一的结论,据此提出了具有针对性的工程处理措施.
An asphalt pavement brought about an accident on cracks in advance.Oil dipper experiment was in progress by way of test samples on-site extraction.The comparison and analysis of the relative factors,producing asphalt content（oil-stone ratio） is due to the low asphalt concrete pavement is one of the main causes of cracking in advance of the conclusions,the paper puts forward the corresponding treatment measures with engineering.
