Specialized Engineering utilizes its AASHTO (CCRL/AMRL), USACE, and DOT accredited laboratory facilities for conducting standardized (ASTM, AASHTO, etc.) and specialty testing and analysis of construction materials. The ASTM and AASHTO testing methods are conducted to determine material properties of proposed materials in new construction projects, establish material properties in existing structures, or to investigate material failure and performance problems. Below are the most common testing services performed on a daily basis by our technical personnel:
