emulsion stabilisation trial

emulsion stabilisation trial

20 November 2020

Last week Road Science undertook a bitumen emulsion stabilisation trial with the Waikato District Alliance and Downer Stabilisation Team. Nik Vishwanath introduced the teams to a new Road Science product Enviro Base.

The product was added directly into the drum of Downer's Wirtgen WR2000 Stabiliser and was found to improve the speed and quality when constructing the pavement.

Enviro Base greatly improves the impermeability of the material and the constructed pavement can withstand longer periods of time unsealed without raveling away and potholing. This allows construction crews to be more efficient when scheduling their first coat seals.

If you have any questions about this product contact Nik Vishwanath.
