Foam Bitumen Cement and Lime Stabilisation Design
Liquid Labs WA can provide the onsite sampling, testing, and recommended designs for the rehabilitation of trafficked pavements.
The use of stabilisation techniques in the construction industry is continually being increased due to its ability to reuse and recycle existing materials. Stabilisation is a widely accepted cost-effective methodology used to increase the long-term performance of mainly heavily traffic pavements. Key additive components used in the industry are Cement, Lime, and Foamed Bitumen.
These materials are normally used in combination to increase its compressive strength while increasing it tensile strength. An Investigation for an asset’s rehabilitation starts with assessing the pavements layer thickness followed by the onsite site simulation of stabilisation and sampling.
This is then followed by in house laboratory testing and simulations.In the case of Foamed Bitumen Stabilised materials, sampled material are stabilised at set bitumen and cement/lime contents using laboratory purposed scaled down version of the onsite foaming stabilisers. In this assessment we are trying to find the additive %’s that would result in the greatest performance. Resilient Modulus is the most common test methods used to assess this performance.
