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
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).
