Meta-Analysis of Soil Property Relationships and Construction Platform Design

This paper introduces the concept of using an existing low-volume road design method to lower granular layers within a mechanistic-empirical ensure adequate construction platform. The DCP-DN was chosen because it has advantages over other cover-based empirical methods in this context, including utilizing full-depth measurement and requiring balanced layer profile. To implement use field Dynamic Cone Penetrometer (DCP) data design, relationship convert between stiffness DCP penetration index required. A new set internally consistent relationships various soil strength parameters thus developed, meta-analysis 126 models published since 1960s. These were used develop nomograph for estimating properties soils.
