Laboratory Services

Speedie & Associates operates modern, well-equipped construction materials laboratories at all three Arizona office locations. These are capable of analyzing the mechanical and physical properties of soil, aggregate, asphalt and concrete as well as providing support for our geotechnical and field services departments. Our laboratories participate in proficiency programs administered by the Arizona Department of Transportation (ADOT), New Mexico Department of Transportation (NMDOT), the City of Phoenix (COP), the Cement and Concrete Reference Laboratory (CCRL) and the AASHTO Materials Reference Laboratory (AMRL). Laboratory testing services are conducted by certified technicians in either our permanent facilities or in one of our fourteen mobile laboratories which can be mobilized to a specific site when desirable due to project location or the need for expedited testing timeframes.

For laboratory testing, Speedie & Associates owns and maintains equipment necessary to perform a wide variety of tests. A partial listing of these includes: SHRP Gyratory Compactor, Asphalt Ignition Furnace, Liquid Asphalt Lab, Flexible-Wall and Constant Head Permeability Equipment, Marshall Compactor, California Bearing Ratio Equipment, Compression Machines, Direct Shear Device, Atterberg Limits Apparatus, Kneading Compactor, Hveem Asphalt Test Equipment, and R-Value Test Equipment.

Speedie & Associates Materials Laboratory is a leading provider of asphalt mixture design services and materials source evaluations. In addition, our staff has the knowledge and ability to provide a full range of aggregate, concrete, fly ash and cement testing services.
