Laboratory testing is required for both QA/QC and for design purposes. In many instances, lab testing is required on earth materials to determine their engineering properties, such as maximum relative density, moisture content, and grain size, to ensure that compaction and type of material being used on site meet design and specifications. In other instances, laboratory testing is used to help aid in geotechnical design, such as determining the permeability of soils, the strength of soils and how they relate to foundation construction, and settlement parameters.
Laboratory services that Central Earth Engineering provides include:
- Proctors and grain size analysis on soils and aggregates
- Sieves, hydrometers and Atterberg limits on soils
- Concrete compressive strength
- Asphalt AC content and gradation
