The AASHTO accreditation program recognizes the competency of a testing laboratory in construction materials testing by assessing both the equipment and the staff’s abilities. The accreditation process is often long and arduous, however, Geotechnical & Environmental Services, Inc. (GES) has proudly been AASHTO certified for the last 20 years. GES’ AASHTO accredited lab provides the following lab testing: Soil Testing ASTM D421 Dry Preparation of Soil Samples ASTM D422 Particle Size Analysis of Soil ASTM D698 Laboratory Compaction of Soil Using a 5-lb.
