Abstract
This paper presents findings from a field study conducted with a smooth drum vibratory roller equipped with machine drive power (MDP) and accelerometer based compaction meter value (CMV) technologies. Two test sections with layered granular materials were mapped using the roller and tested using light weight deflectometer (LWD) and dynamic cone penetrometer (DCP). One area consisted of a thin relatively stiff recycled asphalt material underlain by poorly graded fine sand and the other test area consisted of compacted layers of poorly graded sand. Results indicated that the thin stiff layer in one of the test areas influenced the MDP and LWD measurements more than the CMV measurements. CMV showed deeper influence depths (up to 1 m) compared to MDP (< 0.5 m). MDP measurements correlated well with LWD and DCP-California bearing ratio (CBR) measurements when data from the top 300 mm was used. CMV correlated well with CBR measurements when data from the full profile (up to 800 mm) was used. (161 words)
