DDS Laboratory Receives
and USACE Validation
DDS is excited to announce that our Materials Testing Laboratory has received accreditation by the AASHTO Accreditation Program (AAP). The AAP is the largest and most recognized accrediting body of construction materials testing laboratories. The program scope included an on-site assessment and evaluation of our Quality Management System, personnel qualifications, and demonstration of test methods. On-site assessments were performed by AASHTO re:Source and ASTM’s Cement and Concrete Reference Laboratory (CCRL). The program also requires laboratories to participate in AASHTO re:Source and CCRL proficiency testing programs as a means of monitoring the continued performance of a laboratory.
This accreditation formally recognizes the competency of our staff, equipment, and procedures used to perform several soils, aggregate, and concrete test methods. This accreditation also demonstrates a commitment to our clients to provide quality testing services with reliable results. To view our full scope of accreditation, click here.
Based on the AASHTO Accreditation Program results, DDS has also been validated by the United States Army Corps of Engineers (USACE) Validation Program. A full listing of our validated methods can be found here. Simply search for "DDS" to review our current status.
