Local polymer road solution company Romix has developed products that improve the performance of load-bearing and wear layers of roads while reducing the costs of construction and the impact on the environment, says Romix Africa MD Vijian Naidoo. “Our soil-fix product is used in a liquid form during the construction of the bearing courses of roads. The product penetrates and binds the soil, replacing aggregate layers. We have also developed a wearing-course product that is used above the bearing layer to improve wear resistance.”
