RAY BROCE MATERIALS LABORATORY

This lab is used to teach CE 3404, Macromeritics, and CE 3884, Transportation Engineering. This lab has the capacity to test specimens of aggregates, asphalt, concrete, metals and wood. Equipment for making concrete specimens includes a concrete mixer, cylinder and beam molds, various hand tools and a curing tank. Concrete testing equipment include air meters, a slump cone, cylinder capping equipment a 500-kip capacity compression machine, and a 22-kip capacity MTS load frame. Data acquisition equipment consists of IBM compatible microcomputer with data acquisition adapters.

Asphalt testing facilities include two mechanical convection ovens, an ITC Interlaken Superpore gyratory compactor, a Texas gyratory compactor, NCAT ignition oven, Gilson shaker, floor-type sample splitter, Rice test apparatus, digital balance and other accessories. Facilities for testing asphalt cement are being procured.

SOILS LABORATORIES

CEC 328 is used for instruction in CE 3363, Soil Mechanics and CE 5020 Laboratory and In Situ Soil Testing. The laboratory includes equipment to measure consistency, permeability, gradation and compaction. Strength testing equipment consists of unconfined compression, motorized direct shear and one cylindrical triaxial device, and the lab contains three consolidometers for determining compressibility. The lab also houses a model to simulate seepage through earth dams.

CEC 330 is used for instruction in CE 5020 Environmental Geotechnology and CE 5020 Laboratory and In Situ Soil testing. This room contains equipment for determining soil-water characteristic curves and permeability of unsaturated soils. It also houses an HP Vector Impedance meter for measuring electrical properties of soil.
