Take the High Road

Leiths 

Stone-mastic asphalt thin-surface course systems (TSCS) have been getting a poor press of late due to surfacing failures around the UK, often due to poor laying practice and/or bad weather.  Other factors may include high void and low binder content within the asphalt, deficiencies which are addressed in TS2010, the Scottish surface-course specification. This document thereby ensures a more durable material than the prevailing UK standard, Clause 942 of the Specificiation for Highway Works.

"It stands to reason that increasing binder content and reducing voids will inevitably lead to material with greater durability", commented Neil Anderson, Technical Director of Leiths.
