Bitumen Stabilized Materials

There are three kinds of stabilization that have been successful historically, namely cement, lime and bitumen. All of these products have known test methods and failure mechanisms, all of these products also significantly increase the wet strength of stabilized aggregates. We have become aware of over 40 alternative products for stabilization on the market that do not improve the wet strength of the aggregates and as such cannot be tested or classified according to sound engineering methods. Ecobond is not one of these products, Ecobond is an improvement on bitumen emulsion stabilization.

Ecobond BSM is a synthetic resin reinforced bitumen emulsion which is mixed into an aggregate such as natural gravel or crushed stone for the purpose of improving its engineering properties. Bitumen emulsion stabilization has been used very successfully in many projects worldwide, Ecobond improves the elastic strength (to counter visco-elastic behaviour) and water resistance (to reduce moisture sensitivity) of bitumen stabilized aggregates potentially allowing a design engineer the option of achieving the desired properties at a lower binder content (price), or utilizing a more durable design at a similar price. Ecobond reinforced bitumen stabilization has shown its worth in scores of commercial applications and thousands of laboratory tests over the past 15 years in the SADC region, Europe and pilot projects in the Middle East and Australia.
