Application Procedure
Soil stabilisation is essentially a quick and easy procedure. However, in order to achieve a successful and lasting result, experienced machine operators and construction supervisors are required in addition to suitable machinery. Moreover, a soil analysis and a suitability test are essential before construction work commences. Compared with conventional soil stabilisation, additional requirements are placed on all those involved in the processing of DuraCrete. As a successful outcome and high quality are important to us during the processing procedure, we support our partners in all stages of the project.
Application Procedure
1. Milling and Breaking Up Old Asphalt
Milling off the old asphalt coating.
Breaking up the remaining asphalt coating with a grubber (optional).
Mixing and crushing asphalt and ballast using a stone mill (optional).
2. Spreading DuraCrete / Cement Mixture, then Mill Mixture
Applying the exact quantity of DuraCrete defined (according to the suitability test).
Applying the exact quantity of cement defined (according to the suitability test).
Milling the DuraCrete/cement mixture into the native soil while adding water.
3. Compacting, Irrigating and Smoothing
Compaction with a smooth roller (8–12 tons).
Using a grader to create the finish grade.
Irrigating the surface to prevent it from drying out.
4. Applying a New Asphalt Layer / Optional
Apply new asphalt layer.
New asphalt coating can be applied after just 24 hours – this is usually dimensioned much thinner than conventional top layers that are applied to road construction.
