Abstract

This paper presents a dynamic California Bearing Ratio (CBR_d) device that can be used on a prepared pavement foundation layer to obtain a certain parameter of the tested material in the laboratory and in situ in a direct and fast way. For the selected natural material (gravel), it is shown that the laboratory CBR_d can be used to estimate the compaction and bearing capacity, because it correlates well with the parameters of the standard and modified Proctor compaction tests. Comparative tests revealed that there is good correlation between the field CBR_d and the deformation modulus, and dynamic deformation modulus values obtained by field tests.

路面基础层动态 CBR 与压实度和承载力之间的相关性

本文介绍了一种动态加利福尼亚承载比（CBRd）装置，该装置可用于已准备好的路面基础层，以直接、快速的方式在实验室和现场获得受测材料的特定参数。对于所选的天然材料（砾石），试验表明实验室 CBRd 可用于估算压实度和承载力，因为它与标准和改良 Proctor 压实试验的参数有很好的相关性。对比试验表明，现场 CBRd 与现场试验获得的变形模量和动态变形模量值之间存在良好的相关性。
