Continuous Compaction Control Technology for Granite Residual Subgrade Compaction
Source abstract
Abstract
The implementation of roller-integrated continuous compaction control (CCC) technology on three types of granite residual subgrade (GRS) was evaluated in this work; the three types of GRS are cement-treated GRS, GRS with aggregate, and natural GRS. Four common roller measurement values were calculated and analyzed: compaction meter value (CMV), compaction control value (CCV), machine drive power (MDP), and acceleration amplitude (AA). Both the sand cone test and the geodetic leveling test were conducted to evaluate the soil compaction efficiency during construction. Results revealed that cement-treated GRS could be compacted more easily than untreated materials with the same compaction effort. The correlation analyses between point measurements and roller measurement values indicate that the optimum roller measurement values for the cement-treated GRS, the GRS with aggregate, and natural GRS are CMV, AA, and CMV, respectively. Meanwhile, roller measurement values strongly rely on roller operation parameters and lift thickness, especially for the cement-treated GRS.
