Abstract

This study compares the measurement of skid resistance using GripTester andSCRIM carried out in September 2005 on a micro asphalt trial site on a major route in the South East of England. A comparative assessment of skid resistance measurement techniques using SCRIM, GripTester and pendulum was carried out. The principle aim was to determine whether the 2005 TRL SCRIM / GripTester correlation applied to micro asphalt. This was important as this type of surfacing had not been assessed during the 2004 TRL correlation study and the GripTester was being used to evaluate the early and mid-life performance of the different micro asphalt road trial test sections. The study set out to determine relationships between the two methods, as well as measure skid resistance using the two main methods available in the UK i.e.SCRIM and GripTester. Further objectives were to determine whether micro asphalt skid resistance values plot in a similar trend to the surfaces assessed during the 2004 TRL SCRIM / GripTester correlation survey. It has resulted in the first full-scale micro asphalt road trial in the UK to assess differing aggregates in the provision of wet skid resistance. This trial has allowed the development of micro asphalt early life skid resistance to be studied for the first time in detail over a two year period. The trial also facilitated the first UK SCRIM / GripTester skid resistance measurement correlation study for micro asphalt.
