Laboratory Test Materials (Soils, Aggregate, Asphalt)

GWV field geologists and technicians are responsible for sampling, testing, and documentation while performing geotechnical investigations and/or testing services for foundation construction, rough grading, infrastructure and street improvements, tie-back installations, and other construction projects. Construction monitoring is planned based on our thorough understanding of the project specifications, test methods, and schedules.

Test Methods Include:

• Asphalt Content (Ignition Oven), ASTM D 6307
• Asphalt Content (Solvent), ASTM D 5444
• Compaction Test (nuclear gauge & sand cone)
  • Relative Compaction (Density) of in-place soils (sand cone), ASTM D 1556
  • Relative Compaction (Density) of in-place soils (nuclear), ASTM D 6938
  • Relative Compaction (Density) of Bituminous concrete (nuclear), ASTM D 2950
• Direct Shear Test, ASTM D 3080
• Durability (coarse and fine)
• Expansion index of Soils, ASTM D 4829
• LTMD – Asphalt
• Maximum density/optimum moisture determination, ASTM D 1557
• Mechanical Analysis of Soils, ASTM D 422
• Moisture Density
