T-RRP 235 Spezial (Ground Stabilization) -
Specifications:
Roads and places need, like all buildings, load carrying and non freezing subsoil. With the conventional method, soil is dug up to 1.5 meters deep and large quantities of earth has to be removed, and replaced by layers of lime, gravel and crushed stones. In the end, the surface of bitumen-gravel and bitumen-concrete is applied. All of this entails large costs of machines and personnel and involves a lot of time. And again and again, immense damage by penetrating water and the following dry clefts cannot be avoided. Expensive repairs become necessarily. Often an important transport connection is completely interrupted. No wonder that many have been looking for alternatives.
The T-RRP method offers an alternative effective way, which stops penetrating water and frost problems.
The soil is no longer dug up, but -- after the removal of the humus layer -- only loosened. Then the water-T-RRP solution is sprayed onto this soil, and, if necessary, the top crust is loosened by the help of a milling machine. As soon as the water solution has seeped into the soil, and its effect unfolded, the soil is consolidated simply by a vibrating roll (minimum pressure 10 tons).
On this mechanically consolidated soil, a relaxation and wear surface layer can be applied immediately.
A barrel T-RRP-concentrate (210 liters) can create the substructure for 1 kilometer of road. Depending on condition of the soil, the water solution is enough for an area of 7,000-10,000 m2.
Result of the T-RRP building method: great cost and time savings
With the better compression of the soil after T-RRP treatment, the maximum stress is considerably higher than with comparable conventional building method. Thus for example measurements of pressure on a road for tanks in Germany, built with T-RRP, values of 4,000 kilograms per square centimeter were measured. This is many times over the values demanded for German motorways.
Where to use T-RRP
T-RRP is suitable for all connecting clay and loamy soils, which have a portion of silt and flour of at least 15%. All other soils should be examined in the laboratory whether they can be stabilized with T-RRP. Pure sand and gravel soils as well as boggy soils are unsuitable e.g. without pretreatment. Because of its special characteristics, T-RRP is especially suitable for the solidification of such soils, which are sensitive to frost and only difficult to consolidate because of their high water content. T-RRP promotes a good drainage of these soils.
That is how they become durable drying. Frost damages and dry clefts by pouring and shrinking clay/tone particles in the substructure are durably prevented by T-RRP-treatment.
