沥青路面压实度无损检测技术探讨

Discussion on Non Destructive Testing Technology for Compaction Degree of Asphalt Pavement

压实度是沥青路面质量评定的关键指标,在公路工程质量检测中,沥青路面质量检测的关键项目之一就是压实度。若压实度偏低,则会大幅降低沥青路面使用年限,甚至危及行车安全。沥青路面压实度检测方法中,一般可分为破坏性检测和无损检测,后者检测速度快,且对沥青路面不会造成破坏,目前已广泛应用于公路工程沥青路面检测中。

Compaction is a key indicator for evaluating the quality of asphalt pavement.In highway engineering quality inspection,one of the key items for asphalt pavement quality inspection is compaction.If the compaction degree is too low,it will significantly reduce the service life of the asphalt pavement and even endanger driving safety.In the testing methods for asphalt pavement compaction,they can generally be divided into destructive testing and non-destructive testing.The latter has a fast detection speed and does not cause damage to the asphalt pavement.It has been widely used in asphalt pavement testing in highway engineering.
