Increasing Slope Stability
maxit LWA will also reduce the risk of bearing capacity failure and increase the stability of the side slopes.

Providing Efficient Drainage
Efficient drainage of the structural layers of the road build-up can prevent loss of load bearing properties caused by water and ensure a good load bearing capacity throughout the road life.

Using free draining maxit LWA within the road build-up will break the capillary rise of ground water into the upper construction layers whilst performing as a structural material and improving the load bearing capacity.

In sloping terrain and in cuts stretching below the surface of the ground water, streams of ground water can cause localised damage to the road surface and reduce the load bearing capacity of the road.

maxit LWA used as a drainage layer within the road construction will intercept the percolating water and water rising by capillary action from the sub-formations and direct the rising water.

With carriageways in cuts that extend below the natural level of the groundwater, frost damage and loss of load bearing capacity can also be reduced by forming drain trenches filled with maxit LWA at both sides of the road, along which the water is led away.

Used within the carriageway drainage, maxit LWA helps filter and increase microbiological breakdown of pollutant runoff from fields and highways.

1. Used in place of general fill, maxit LWA can be used to strengthen the slope face of an embankment.

2. Excellent insulating properties make LWA the ideal filling for road and railway embankments where frost stability requirements determine sub-base thickness.

3. In sloping terrain, cuttings and ground which has high groundwater levels, LWA drainage trenches and drainage layers can be used to dryout road and rail structures and keep them free draining to prevent pore water pressure build-up, slope erosion and provide slope stability.
