Revolutionizing Road Construction

HITEC road® is a powdered additive designed to enhance the properties of conventional Portland cement. When mixed with cement and the appropriate amount of water, it promotes the formation of crystalline structures during the cement hydration process. This results in roads with increased bearing ratios, neutralized pH levels, and water-resistant layers, significantly improving the quality and durability of the constructed roads.

The use of HITEC road® in road construction offers several advantages. It can reduce construction time by up to 70%, leading to substantial cost savings. Roads built with HITEC road® exhibit enhanced quality and durability compared to conventionally constructed roads. Additionally, surfaces made with HITEC road® can be easily restored to their original state. The product is also environmentally friendly, capable of re-stabilizing and immobilizing contaminated soils, thereby aiding in the restoration of natural soil conditions.

HITEC road® significantly outperforms conventional cement stabilisation in both strength and efficiency of the hydration process. With HITEC road®, a load capacity of over 150 MN/m2 is established just 2 days after the hydration process begins, compared to ≤150 MN/m2 after 28 days with conventional methods. The total hydration process with HITEC road® takes approximately 90 days, achieving a load capacity of ≥230 MN/m2 without the risk of cracking. This is due to the formation of long crystal needles during hydration, enabling very high bearing strengths.

HITEC road® offers several key advantages over traditional methods. It increases strength by 25% to 45%, enhances flexibility by 30% to 50%, and improves frost resistance by 25% to 40%. These improvements contribute to the overall durability and longevity of road surfaces. Additionally, it enables cost savings of over 30%, making it an economically viable choice. The ability to stabilize soils with high salt content and the resistance to problems caused by frost, thaw, or changes in conditions are significant environmental benefits. HITEC road® allows for the construction of water-resistant base courses even from in-situ soils, further emphasizing its environmental friendliness.

HITEC road® is versatile in its application and can stabilize a wide range of soil types. It is effective on soils that include clay, sand, shale, and even oil shale. Additionally, it can stabilize single grain sands and soils with high organic matter content. Its unique formulation also allows for the stabilization of soils that are high in salt content, which is often a challenge with conventional stabilization methods.

HITEC road® is designed to be highly adaptable and can stabilize a broad spectrum of soils. From the information provided, it appears that there are no specific limitations mentioned regarding soil types. Its efficacy in stabilizing diverse soil compositions, including those with challenging characteristics like high salt content or organic matter, demonstrates its robust applicability in a variety of construction and environmental contexts.

The stabilized layers created with HITEC road® exhibit a very high load bearing capacity, which is a direct result of the long needle-like crystals formed during the hydration process. This unique crystal structure significantly enhances the strength of the stabilized layer. Additionally, these layers possess high tensile strength, enabling them to effectively absorb vibrations from heavy trucks and equipment. This makes HITEC road® an ideal solution for constructing durable roads and surfaces that are subject to heavy traffic and mechanical loads.

HITEC Road layers are designed to be water impermeable, which is a critical feature contributing to their overall strength and durability. This impermeability prevents water penetration, a common issue in traditionally based layers where water ingress can lead to compaction failure. The hydration process of HITEC Road involves the formation of long needle-like crystals, which not only support heavy loads but also create a flexible base. This flexibility, combined with water impermeability, ensures high durability and maintains the structural integrity of the road or surface under various environmental conditions and heavy usage.

The use of HITEC road® offers significant advantages in maintaining road surface quality and enhancing durability. One of the primary benefits is the substantial reduction, or even elimination, of potholes. This is a common issue in many roads that leads to frequent and costly repairs. Additionally, HITEC road® effectively prevents the formation of washboards, which are corrugations that can develop on gravel roads. The product’s frost-resistant properties also contribute to its overall durability, particularly in cold climates where frost can cause significant damage to road surfaces. Furthermore, the higher strength and increased flexibility of the base layer provided by HITEC road® help in avoiding structural failures, such as cracking in the asphalt layers. These attributes result in a more resilient road surface that requires less maintenance over time.
