1.1 This part of BS 598 specifies a method for determining the susceptibility of bituminous materials to plastic deformation at high road temperatures under pressures similar to those experienced on the road. The method applies to any bituminous wearing course material laid at a nominal thickness of up to 50 mm and is carried out on samples cored from laid and compacted material.
1.2 The test is usually carried out at a temperature of either 45 °C or 60 °C, but other test temperatures can be used.
NOTE 1 For research purposes, it may be necessary to determine the wheel-tracking rate of laboratory-prepared and compacted mixtures. However, this requires a carefully controlled and detailed procedure for specimen preparation and compaction, which is not included in this standard, but which, it is hoped, will be described in a future Draft for Development. Nevertheless, with the necessary changes, this method can be used for laboratory-prepared specimens.
NOTE 2 Precision data determined from experiments are given in annex A.
