The PAFV test and road friction

In Australia, the measurement of aggregate polishing values can be obtained from either using a horizontal testing wheel / flat mould system as developed and applied to polished aggregate friction value (PAFV), or a vertical testing wheel / curved mould system as developed for polished stone value (PSV) and applied to Australian PAFV. What caused this to happen, and does it really matter? Meanwhile, there is continuing debate overseas regarding the limitations of the PSV test. It has been postulated that PSV is only a ranking method dependent on the stressing conditions imposed during the test, and that PSV provides some indication of on-road skid resistance performance of an aggregate but surfacing type and aggregate source may be a more important indicator. Is it time for a new test? This paper summarises the results of a literature review into these issues. (a) For the covering record of the conference, please refer to ITRD no. E218387.
