Applying Geostatistics to Continuous Compaction Control of Construction and Demolition Materials for Road Embankments

Continuous compaction control (CCC) with constant roller settings provides useful data on the stiffness of the layers involved. By carefully analyzing the data, it is possible to estimate how compaction will evolve during the construction process. Applying geostatistics to CCC data means that spatial variability can be quantified, something that is difficult using simple statistical analysis. Univariate statistics of CCC measurements alone do not describe spatial variability, and neither do they address the issue of uniformity from a spatial standpoint. Furthermore, it is important to choose the variogram model wisely, so that the factors distinguishing the areas being investigated can be fully appreciated. This article was prepared using statistics and geostatistics on experimental data obtained from an embankment made of recycled materials.
