Field testing was carried out to validate the K factors of the ball penetration test and found generally comparable trends to the previously determined laboratory data. Consequently, a replacement K factor (0.06) was recommended for fatty roads and asphalt surfaces (currently 0.08). Extensive field work was carried out to investigate factors affecting ball penetration test on unsealed/primed bases. It was found that the moisture content of the base was the major factor affecting the ball penetration test. The findings in this report were based on a limited amount of data collected for this study and thus further field data (K factors and base investigation) need to be collected from other areas of Australia and New Zealand.
