The Portland Cement Association (PCA) has a “Soil-Cement Frequently Asked Questions (FAQs)” repository website. Each link has a variety of information as well as additional links, papers, publications, photos graphs, equipment suggestions, etc., for inquisitive minds who are looking for answers to their concrete pavement construction project(s). Topics of the FAQs:
- Roadway materials treated with cement?
- Base material cost advantages
- Cement slurry vs lime slurry
- Pugmill for CTB
- Newly constructed cement-stabilized roadway bases
- Rehabilitation of roadway through FDR
- “Rule of thumb” for water to use in soil-cement
- Portland cement with a given FDR pavement project
- Soil-cement bases-processes and problems
- Soil-cement compressive or flexural strength test results
- Types of soil-cement materials
- Micro-cracking/pre-cracking of bases
- Product comparisons in stabilizing clay soils
