Materials Testing
ACS Testing, Inc. provides lab and field testing of soils, asphalt, concrete, masonry, and steel to ASTM, AASHTO, and ODOT standards.
Soil and Aggregate Testing
We test soils and aggregates to confirm they’re suitable for construction, measuring compaction, gradation, strength, durability, and cleanliness to ASTM, AASHTO, and ODOT standards.
