Facilities at The Pennsylvania Transportation Institute (PTI) The Pennsylvania Transportation Institute is headquartered on the University Park campus and is a major intercollegiate research unit of Penn State that involves faculty and students from the colleges of engineering, agriculture, business administration, education, health and human development along with personnel from other research units in the university system, such as the Applied Research Laboratory, the Center for Applied Behavioral Sciences, and Penn State Harrisburg. PTI focuses on solving problems in the following areas of transportation research: transportation structures, construction, materials, pavements, transportation operations, and vehicle systems and safety. Through PTI, Department of Civil and Environmental Engineering faculty and students in the structural engineering program have access to additional testing facilities beyond the Sackett Structures Laboratory. At the PTI test track facility, a full-scale bridge test site and large-scale pendulum are available. The full-scale bridge test site permits controlled field testing of single and two-span bridges with lengths over 37 m (120 feet). The large-scale pendulum consists of a 15.25 m (50 ft) high steel frame capable of swinging weights of up to 67 kN (15 kips) through an arc with a vertical drop height of up to 13 m (42 ft). Additionally, extensive facilities and equipment are available for material testing and characterization. These facilities include laboratories for concrete mix design and curing, environmental effect simulation, long-term behavior monitoring, and destructive and nondestructive testing.   Large Scale Impact Test with Vehicle as Mass for Barrier Impact.
