The Hillman-Composite Beam (HCB®), is an innovative structural member for use in highway and railroad bridges as well as marine facilities. The HCB is essentially a lightweight reinforced concrete beam strengthened and protected by a corrosion-resistant and resilient Fiberglass Reinforced Polymer (FRP) shell.
The beam is comprised of three main components, a concrete arch (compression reinforcement), an FRP bottom flange encapsulating steel strands tying the ends of the arch together (tension reinforcement) and the FRP shell. Galvanized Rebar “shear connectors” are used to make the beam composite with the concrete deck in the same manner as pre-stressed concrete beams.

ECT Fact Sheets
Conventional horizontal concrete slabs are heavy that limit their spans. Enhancement of span results in addition of beams that increases the cost of the structure. Thus, there is a need for a technology that will help in increasing the span by reducing weight of the span. BubbleDeck is a revolutionary construction method that virtually eliminates concrete from the middle of a floor slab between columns that does not perform any structural function, thereby dramatically reducing structural dead weight. BubbleDeck is based on a patented technique - the direct way of linking air and steel.

ECT Fact Sheets
The Superpave is the acronym for 'SUperior PERforming Asphalt PAVEments' system. It was developed by Strategic Highway Research Program (SHRP) to give highway engineers and contractors the tools they need to design asphalt pavements that will perform better under extremes of temperature and heavy traffic loads.
