Laboratory Testing
AAI PROVIDES TURNKEY ENGINEERING ROCK TESTING SERVICES AT ITS GRAND JUNCTION, COLORADO LABORATORY.
AAI has been providing reliable and expedient materials testing in support of mining and civil engineering projects for over three decades. Established primarily to serve the regional coal industry, our lab has expanded to accommodate the diverse needs of modern engineering and has grown to become an internationally recognized service provider.
Samples are prepared in strict accordance to American Society of Testing & Materials (ASTM) and/or International Society of Rock Mechanics (ISRM) standards. Our 500,000-lb load frame is regularly maintained and calibrated by a licensed third-party provider, and our axial and circumferential extensometer system can accommodate elastic properties testing of NQ-, HQ-, and PQ-sized core.
Situated only minutes from AAI’s headquarters in Grand Junction, Colorado, our engineers are able to collaborate seamlessly with lab personnel. This offers a balanced level of direct oversight, ensuring each test program is tailored to the client’s needs and allows for thorough and unimpeded analysis.
