ROAD RECONSTRUCTION WITH ROADCEM
To understand the way RoadCem works we have to take a look at the repetitive loads which are typical for roads
when in use; assuming we have a cyclic dynamic loading which is acting through the asphalt to the road base
However it is possible to have these two attributes within one material. Reinforced concrete is a good
example; It has a higher modulus of elasticity than standard concrete, and it is more flexible. As we
know it is not suitable for road base construction and it isn’t needed as RoadCem technology achieves
both these requirements in the following way:-
By forming needle like crystalline growths around and between the particles being stabilised RoadCem
essentially wraps the individual particles together in a dense woven matrix; this is far stronger than
conventional cement bonding between particles which is based on the individual contact points
between adjacent particles being ‘glued’ together – a more unstable connection leading to brittle
behaviour.
The wrapping effect produced by the inclusion of RoadCem is far more effective at binding soils
and weaker aggregates than traditional cement stabilisation, enabling higher loads to be managed
by the stabilised material with much lower deformations and the a far higher average dynamic
modulus than conventional cement stabilisation alone.
