Surfacing aggregate skid resistance performance

To obtain the best whole of life aggregate selection to achieve appropriate skid resistance, the nature of polishing of individual aggregates needs to be understood. Polished Stone Value (PSV) testing, often does not provide an indication of on road performance. The requirement for PSV test contained in NZTA's aggregate specification MI6 references "BS EN 1 097-8:2009 Tests for mechanical and physical properties of aggregates". The objective of this presentation is to discuss the outcome of extending the second polishing stage in this test method. Existing test results and further ones to be completed by the middle of 2013, appear to confirm on road experience of aggregate performance in the Bay Of Plenty region of New Zealand. The presentation will examine any correlation with onsite skid testing with weathered and un-weathered sedimentary and igneous scoured aggregates as well as the use of this exercise to train practitioners.
