Material Stabilisation Technology
Complying with all environmental and OH&S requirements PolyCom is a material stabilising water additive. When mixed with water at the point of application, PolyCom, (delivered as a powder), forms a highly viscous homogeneous liquid.
When applied to the material PolyCom facilitates a web-type mechanical binding action. The pavement fines and crushed stone slip into a more tightly bound compacted mass. PolyCom provides greater material density which, by design, delivers a more resilient carriageway reducing the “washboarding” type traffic and water born erosion damage.
Why stabilise the material?
The primary purpose for using stabilisation is to slow down the rate of deterioration by;
-
Increasing sheeting (wearing course) life
-
Reduce maintenance intervention
-
Lower life cycle cost
-
Increase road user safety
-
Improve marginal material performance
When evaluating whether stabilisation is required polymers should always be considered. Traditional stabilisation methods, like the use of cement and or lime, have been around for more than 60 years. Polymer stabilisation heralds a new era in the road construction industry. In many cases outperforming traditional methods!
The NATIONAL PROTOCOL VERTICAL SATURATION TEST is used for any binder and is in the process of becoming an Austroads test procedure as detailed in Austroads technology Series part 4d "Stabilised Materials" (the officially recommended laboratory testing method is available on this website).
Most users of PolyCom technology see substantial financial benefits. Over the past 8 years, practical and visual performance together with real cost reductions has seen traditional stabilisation methods challenged by our product..
In real terms, 40% of all cement and or lime stabilisation requirements can be substituted by applying PolyCom to the material. In terms of costs, the savings can be enormous. The cost of stabilization is reduced by;
-
Reductions in raw material transport costs (enough product for 1km road of road delivered in a ute)
-
Elimination of specialized equipment costs (no stabilising machines required)
-
Providing dexterity to reshape the material after extended periods of inaction (incorporated plasticity factor)
-
Delivering the ability to delete the resheet in many instances (use in situ materials by scarification grading)
-
Contributing to the “big picture” in long term asset management plans. (fact)
