TS2010: a surface course designed for safety
This paper will describe the introduction of the new performance based specification which is expected to deliver significant improvements in material durability, value for money, safety, and potentially allow for the use of locally won materials and reduce disruption to road users caused by road construction and maintenance. Further research as demonstrated that the SMA provided a larger contact area between the vehicle tyre and the surface of the road. This provided the 'grip' that is apparent in the testing completed to date. This would suggest that smaller nominal size SMA's should be used for increasing stress sites as they will provide higher skidding resistance and be more durable and less likely to fret. The specification TS2010 is now available and it is hoped that it will be used on all new pavements and on pavements that are structurally sound from a maintenance point of view. The policy is that this material should not be used on unsound pavements, as we expect this material to perform for 16 years plus.
