GB5

Globally increasing traffic volumes, heavy vehicles in particular, led to the development of specialised asphalt mixes that perform well without premature rutting or cracking under extreme loading.

GB5 High Modulus Asphalt System is a high-performance asphalt mix paved in a conventional manner. It consists of graded crushed aggregate, Styrene-Butadiene-Styrene (SBS) modified bitumen, filler and reclaimed asphalt (RA) up to 25%. It is applied as a base or surface pavement layer.

GB5 was developed by French company Eiffage Travaux Publics, from whom AECI Much Asphalt acquired the rights to manufacture the product. AECI Much Asphalt has undertaken various successful GB5 trials on high traffic routes and has been awarded an Agrément Certificate for the product.
