Title:

Roller-Integrated Continuous Compaction Control for Granite Residual Soil Subgrade Construction

Abstract:

This paper documents experiment study of using roller-integrated continuous compaction control (RICCC) on granite residual soil (GRS) subgrade construction in Jiangxi, China. Three test sites, representing cement treat granite residual soil subgrade (CTGRS), granite earth-rock subgrade (GER), and natural granite residual soil subgrade (NGRS), were tested in this work. Roller measurement data was collected and analyzed as long as the in-situ sand cone method and geodetic leveling conducted in the test sites. Results from the field tests were analyzed to evaluate: (1) differences in roller measurement values (RMV), relative compaction (RC), and cumulative deformation rate (CDR) with increasing pass number, (2) the optimum RMV among acceleration amplitude (AA), compaction control value (CCV), compaction meter value (CMV), and machine drive power (MDP) for certain GRS subgrade, and (3) RMVs dependence on roller velocity, excitation state, and compaction lift. The results, analysis, and experiences presented in this paper can help accelerate implementation of RICCC into the construction of GRS subgrade and supplement RICCC specifications.
