Technical Paper
Background
There have been a number of developments in more durable surfacings in the UK in the last 10 years including: TS2010, which is now the material of choice on the Scottish trunk road and motorway network and has shown clear benefits in terms of durability and surety of performance; while W2020 in Wales is a similar material to TS2010. The specifications for TS2010 (Transport Scotland, 2018) and W2020 (Welsh Government, 2020) use skid resistance as the performance criteria rather than the surrogate of texture which has been used historically on the English trunk road network.
