A purpose-designed stabilising cement from AfriSam is said to provide engineers and contractors with a dependable high-performance solution for improving the strength, durability and longevity of road layers - particularly in challenging local conditions.

Developed specifically for road construction applications, AfriSam says its Roadstab Cement enhances the performance of in-situ materials used in base and sub-base layers. The result is a stable platform that offers superior load bearing capacity and improved resistance to deformation, aimed at ensuring that roads can withstand high traffic volumes and harsh climatic conditions.

According to AfriSam cementitious executive Vishal Aniruth, AfriSam Roadstab Cement has been formulated to meet the exacting demands of road layer stabilisation. “It provides superior strength gain and reduced shrinkage cracking, ensuring that the stabilised base layers perform optimally over the road’s design life.”

“The product’s controlled composition ensures predictable setting times and uniform strength development, which helps contractors maintain tight construction schedules without compromising on quality,” he says. “Its versatility across different soil types and project scales has made it a trusted choice for both urban and rural roads across Southern Africa.”

It is manufactured using specifically selected clinker replacement materials that reduce its carbon footprint compared to conventional cements.

“By using Roadstab Cement, contractors are not only achieving a cost-effective and durable road construction solution, but are also actively reducing the environmental impact of their projects,” says Aniruth. “It is a practical example of how innovation in materials can support sustainable infrastructure development.”

AfriSam affirms that its product’s proven consistency, ease of use and environmental benefits make it a preferred choice for road projects, underpinning critical transport infrastructure across Southern Africa.

The company also highlights its extensive technical support network and notes that its laboratory and field services teams assist clients with mix designs, materials testing and quality control.
