Polymer Pavements, having developed their industrial strength SoilTech polymer stabilisers, for heavy haul mine roads, has now extended its service offering to the local road construction industry in South Africa.
Polymer Pavements MD, Nick Muller, says that the technology of SoilTech, which Polymer Pavements owns, offers this industry several benefits.
“Field and lab tests have indicated that SoilTech polymers easily meet and exceed the American Association of State Highway and Transportation Officials (AASHTO) 80kN single axle load tests, which is a standards setting body for highway design and construction throughout the United States. Therefore, this technology could offer the road construction market far quicker service delivery, at reduced costs.
“Further, the inherent flexibility in polymer stabilised roads results in dramatically reduced maintenance overheads, as opposed to the rigid pavement structures of conventional cement roads.”
SoilTech is used all over the world for the stabilisation of base and sub base layers. Roads can be built three times quicker with a substantial saving compared to traditional cement stabilisation.
In South Africa, Polymer Pavements has used SoilTech polymers on various mine-haul roads, which in many instances carry 350 ton haul trucks. The company has also used the product in Swaziland, Mozambique, Tanzania, and extensively in India.
Polymer Pavements focuses exclusively on manufacturing polymer products for use in road construction and for dust suppression. While polymer technology has been commercially available in various forms for more than 100 years, the use of polymers for road stabilisation is a relatively new technology and has only been under development for the past fifteen years or so.
Muller concludes that SoilTech polymer stabilisers can help revolutionise the road construction industry.
“To advance in any industry, one needs to think outside of the box to offer innovative yet practical solutions. Undoubtedly, SoilTech fits into this category of innovation and forward thinking, and could potentially have a great impact in developing groundbreaking technologies for the road construction industry. Road aggregate is becoming a scarce resource, and our technology substantially reduces the need for road aggregates.”
