Soil Stabilization and Modification Treatments
Equipping you to apply soil stabilization and modification treatments with confidence & success.
Primary Resource
The US Army Corps of Engineers, The National Lime Association, American Coal Ash Association and the Portland Cement Association all have information on design and construction of modified and stabilized soils using their products. Information on these documents are provided in the Additional Resources section.
Soil modification and stabilization for new construction is similar to Cold Central Plant Recycling and for reconstruction is similar to FDR. Before creating a specification for your soil modification/stabilization project, review the documents rom the above listed resources along with the ARRA recommended guidelines for resources in design, testing, quality control, measurement and payment procedures for your project. There are many factors to consider after reviewing these documents and guidelines, and your project may need slight adjustments to meet the localized conditions of your project.
Helpful Guidelines
- Check the depth of the mixing by removing the reclaimer at the begining of each run and measuring the depth
- Check the application rate of the chemical agent being used to ensure that the specifications and mix design are being followed
- Observe compaction to ensure the established roll pattern is being followed
- Time the process to ensure that the final top dress occurs no more than 2 hours after the chemical has been spread
