A solution for high quality seals during the south african winter: the Polycol X and Emulcol Combination
In KwaZulu-Natal, South Africa, Colas has recently introduced the Polycol X and Emulcol combination process in order to allow high quality dressing operations during winter periods. Traditionally, surface dressing operations are performed with hot-applied binders in South Africa during the summer period. During the winter periods the hot-applied binders are not suitable for surface dressing operations.
Stronger bond, faster breaking, shorter closures
The contractor, Fynns Construction, working for the KZN Department of Transport, had approached Colas in Durban to perform a trial section, using Polycol X emulsion on road P58 at Izongolweni on the KwaZulu-Natal (KZN) South Coast.
The seal consisted of a double seal covered with a fog spray. The total seal could be completed in one day.
Both Polycol X emulsion and the Emulcol process are unique to Colas South Africa and give Colas and its customers a strategic advantage in the road construction industry, enabling the company to continue surface dressing operations in the winter months.
The combination of Polycol X and the Emulcol process will allow for considerable cost saving due to increased production rates.
