Materials Engineering Facilities

The graduate laboratories jointly serve both teaching and research needs.

Bituminous Laboratory

The Purdue University Bituminous Laboratory facilities contain conventional and Superpave asphalt binder and hot-mix asphalt (HMA) mixture test equipment required for binder classification and mixture design. Test equipment for conducting laboratory accelerated wheel track and full-scale accelerated testing are also included in these facilities.

Testing equipment includes a Rolling Thin Film Oven (RTFOT), Pressure Aging Vessel (PAV), Dynamic Shear Rheometer (DSR), and Bending Beam Rheometer (BBR) for evaluating asphalt binder. HMA mixture design and testing equipment includes: unconfined and triaxial testing, beam fatigue, and indirect tensile testing. Compaction equipment includes: manual, mechanical and mechanical slant-foot, rotating base Marshall hammers, and two Superpave gyratory compactors. An environmental room or environmental chambers can be used to control temperature and humidity during testing. Facilities for durability testing include high temperature cycling, freeze-thaw and wetting-drying.

Federal, state, and industry sponsors provide funding that employs undergraduate and graduate students, and post-doctorial faculty to conduct problem solving research.

Concrete Laboratory

Practical, hands-on investigation of the mechanical properties of concrete and aggregates.

Charles Pankow Concrete Materials Laboratory

The Charles Pankow Concrete Materials Laboratory has facilities for specialized in-depth analysis of building materials, in particular, cement and concrete. Recent projects have included studies on the early hydration of cement, sulfate attack on concrete by SEM backscatter techniques, the freeze-thaw durability of high-strength concrete, alkali silica reactivity and means to minimize it, influence of silica fume on the pore structure of concrete and image analysis characterization of cement microstructure. This internationally known laboratory was named after Dr. Charles Pankow, President of the Charles Pankow Building, Ltd, whose generous donation has provided for the purchase and maintenance of a significant amount of the equipment found in the lab.
