沥青路面施工压实度变异性研究

Research on Variability of Compactness in Asphalt Pavement Construction

压实度的变异性在沥青路面施工中客观存在。通过在对国道321德庆段路面改善工程沥青路面压实度变异性进行研究的基础上,分析变异性产生的原因及其对路面性能影响,进而提出控制变异性的措施,以减小新修筑沥青路面的压实度变异性。

The variability of compactness is a subjective existence in construction of asphalt pavement. On the basis of the compactness of asphalt pavement （ pavement improving engineering） at De - Qing Section of National Road 321 has been researched with, the paper analyzes reasons for variability and its influence on pavement behavior,further puts forward the measures controlling variability so as to decrease variability of compactness of newly built asphalt pavement.
