The Light Weight Deflectometer (LWD) plays a vital role in confirming that the foundation of a road has been constructed to an adequate standard and in accordance with the pavement design. The LWD is used during construction to measure the effective surface foundation modulus and the consistency of the foundation support along a site length. Sufficient stiffness provides an assessment of adequate compaction and subsequent resistance to deformation. It is therefore essential that there is confidence in the repeatability of the measurements and that it has been calibrated against a recognised standard or measurement. This talk will discuss the findings from the annual correlation trials of LWDs and discuss how the information obtained by these devices provide a powerful tool for checking the quality of foundations and improving durability and longevity of asphalt pavements. |
