Tuffpave®
Tuffpave® is an approved thin surface course system (TSCS) produced in accordance with the Specification for Highway Works (SHW) 942. Tuffpave was developed for motorways and other major highways and can be laid by any licensed laying contractor.
Tuffpave uses high quality, high polished stone value (PSV) aggregates and our specially developed polymer modified bitumen (PMB). Tuffpave is tough on noise, skid resistance and wet weather spray with a texture that is retained throughout its service life. Tuffpave is also tough enough to stand up to heavy traffic yet provide an ultra-smooth ride. Tuffpave is laid by licensed contractors who have gone through an approval process with Heidelberg Materials. Tuffpave comes with a 5-year guarantee underwritten by the contractor.
Tuffpave can also be produced using Heidelberg Materials' era 140 warm mix asphalt process, meeting the requirements of current National Highways major network specifications.
