Weather and Soil Stabilisation
With traditional lime/cement soil stabilisation any rainfall during installation can result in a change in the moisture content of the soils being treated.
This will adversely affect the structure of the stabilisation and its subsequent performance.
However when RoadCem is added this weakness and/or failure will only occur in the most extreme of wet conditions.
It has been proven that when RoadCem is used in the stabilisation process the mechanism of interaction between the stabilised soils/structure and rain/water and Carbon Dioxide in the atmosphere is totally different than in the case of other stabilisation methods, and as a result neither dilution nor carbonation will be a problem
The pavement structure is actually isolated from Carbon Dioxide which leads to the elimination of carbonisation.
Other weather conditions that generally affect the performance of stabilisation are high or very low temperatures. The high air and ground temperatures that we experienced last summer accelerated cement hydration during the stabilisation process, resulting in failures due to loss in flexibility and consequent ravelling of the stabilised soils creating brittle fractures and cracks, even with cement binder mixes of 3% and less. A client of ours prevents this in hot weather by adding RoadCem to his standard mix, the change to a wrapping bind completely cures the problem.
Even in the coldest spells in the winter it worth noting that adding RoadCem will increase protection against low temperature problems. The dense crystalline structure created by RoadCem, prevents voids, squeezing out or trapping any available water to frost proof the stabilisation against all but the heaviest of frosts.
With many projects ground working through cold wet UK winters still has to take place. On these occasions lime will not be an option, but adding RoadCem to your cement mix will be always be beneficial. Please talk to us.
The photo shows RoadCem in use in NW Canada, during a very cold spell, the steam you can see is from the heated water tanker. if you look carefully, you can see that Father Christmas is helping on the Wirtgen soil mixer.
