Gravel roads are a very expensive road system. Dust and weathering result in material loss and is an unsustainable practice.

Ecobond Wearing Courses stabilize the top layer to about C3 or C2 (UCS/ITS and A19/Sil. Carbide aggregate loss) standards to provide a durable water resistant wearing course that reduces aggregate loss occurring due to traffic and environmental weathering creating an ultra-slow wearing course.

Wearing can be predicted based on comparing abrasion and erosion tests to untreated samples, structural layer durability should be determined as per established cemented base course systems. This can also be used in labour intensive erosion control for example on road shoulders to reduce water ingress into the pavement structures and to reduce edge breaks/aggregate loss. Labour intensive construction makes relatively thin layers possible to construct (e.g. 30mm-75mm).
