Evaluation of bearing capacity is shifting towards enhanced Qc/Qa activities by means of non-destructive testing devices and/or roller integrated Continuous Compaction Control systems (CCC).

Assessment criteria are based on the use of CCC measurements and/or independent spot-testing performed with deflectometric devices (Light Weight Deflectometer). Acceptance is based either on CCC results obtained over the compacted area and verified with direct LWD spot-tests, or, alternatively, on CCC proof-rolling measurements alone, for rapid quality control. A third criterion consists in calculation of a CCC target Stiffness Value worked out from a CCC-LWD correlation calibrated on a specific compacted section. Each criterion can be adopted as the single assessment to be performed; alternatively two or more options can be combined to increase acceptance reliability, depending on the importance of the construction or the variability of materials used.

Abstract

Evaluation of bearing capacity is shifting towards enhanced Qc/Qa activities by means of non-destructive testing devices and/or roller integrated Continuous Compaction Control systems (CCC). The aim of this paper was to apply different types of compaction quality assessment criteria to C&D recycled materials compacted using an intelligent compactor equipped with CCC. Assessment criteria are based on the use of CCC measurements and/or independent spot-testing performed with deflectometric devices (Light Weight Deflectometer). Acceptance is based either on CCC results obtained over the compacted area and verified with direct LWD spot-tests, or, alternatively, on CCC proof-rolling measurements alone, for rapid quality control. A third criterion consists in calculation of a CCC target Stiffness Value worked out from a CCC-LWD correlation calibrated on a specific compacted section. Each criterion can be adopted as the single assessment to be performed; alternatively two or more options can be combined to increase acceptance reliability, depending on the importance of the construction or the variability of materials used.
