Geo Technical and Materials Testing

Materials testingDungan Engineering, P.A. has a 2,500 square foot Construction Materials Testing Facility located at the Columbia office and a 900 square foot facility at the Picayune office. This facility staffs approximately 5 Certified Materials Testing Technicians and is capable of performing a variety of tests on soils, concrete, and asphalt. Our Construction Materials Testing Facility is equipped to perform, but not limited to, the following tests:

Soils

  • Soil sieve analysis on fine/coarse grain soils
  • Atterburg limits on fine/coarse grain soils
  • Moisture density relations of soils
  • Soil permeability fine/coarse grain
  • Silt and clay determination of fine grain soils

Concrete

  • Concrete compressive strength
  • Unit weight of concrete
  • Air content concrete  
  • Slump in concrete
  • Fine/coarse aggregate sieve analysis
  • Concrete mix design

Asphalt (Bituminous Materials)

  • Asphalt density in place nuclear method
  • Lab testing of asphalts using the Marshall method
  • Lab testing of asphalts using the Gyratory method

Materials testingOur Construction Materials Testing Facilities performs these tests utilizing a concrete compressive strength machine, Concrete Test cylinder Curing Vat, soils sieves ranging from 3" to #270, standard and modified proctor hammer, standard and modified proctor hammer, a trailer mounted drill rig, and a B54 Truck Mounted Mobile Drilling Rig that is capable of drilling 100+ feet to obtain samples by means of splitspoon and/or Shelby tube.

Our Testing Facility utilizes this equipment, along with other necessary tools, to obtain aggregate samples, perform the required tests, and generate reports on two (2) computers equipped with software specifically designed for the Construction Materials Testing Lab environment.
