Recycled Plastics for Highway Appurtenances

highway cloverleafThis research and development center, supported by a grant from the New Jersey Department of Transportation, answers a call for more economical traffic noise barriers and safer road barriers that use new materials and designs. In addition to material tests, the work will include development of constitutive models and analysis techniques for nonlinear characteristics of the material and its variation through the cross section. Computer simulation will be used to analyze the barriers during a crash by modifying current programs to include recycled plastics models. Experimental study will include wind and acoustic test of the noise barriers and in-field implementation of the proposed designs. An important aspect of this study will be to develop structural analysis methods and design procedures suitable for this new material. Such procedures and methodologies must take advantage of the flexible but ductile nature of the material. Recycled plastics will also be investigated for use in the new aesthetically-innovative noise wall design known as Bhavnani Design and as posts in a Combination Glare Screen/Pedestrian Barrier for New Jersey center barriers.

High Performance Concrete Laboratory

concrete labWith funding from the National Science Foundation, the High Performance Concrete Laboratory in the Civil and Environmental Engineering Department is the only academic facility capable of testing very high strength concretes under uniaxial as well as triaxial states of stress. The primary testing system at this facility is capable of applying up to one million pounds of axial load on specimens under computer controlled closed-loop environment. The system can be programmed to perform triaxial tests with confining pressures of up to 20,000 psi. Concrete specimens can be tested in special environmental chambers under simultaneous cyclic load, and thermal stress conditions. The system can be programmed to apply thermal cycles with amplitudes varying between -50oC to +200oC.

The facility is also equipped with two other closed-loop testing systems for testing of large size beams, and normal strength concretes. The materials processing component of the facility includes two computer controlled micro-sizers, and fractionators for particle size analysis and categorization of industrial by-product additives to concrete, i.e. fly-ash, microsilica, and blast furnace slags. There are two new curing rooms for developing controlled conditions and studying the effects of various combinations of thermal and moisture conditions during early stages of strength development in high performance concretes.

Smart Sensors and Nondestructive Testing Laboratory

This laboratory has been developed in order to provide means for researching and developing self-sensing systems to build into structures that would monitor excessive strains, deflections, load distributions, temperature variations, and corrosion. The Smart Sensors and NDT Laboratory is unique in that the researchers involved consist of an interdisciplinary forum of scientists and engineers with civil, electrical, chemical, and physics backgrounds. The laboratory is primarily involved in developing fiber optic sensor systems for embeddment within concrete, and other emerging composites. The facility is equipped with a number of laser systems, optical spectrum analyzers, speckle based video systems, bench top materials testing systems for calibration of sensors, and supporting electronic instrumentation.

Geoenvironmental Engineering Laboratory

Clean-up of the environment calls for innovative scientific and engineering approaches. Geoenvironmental engineering is a field that unites geotechnical engineering with chemistry and biology in an effort to seek new solutions for the future of the environment. To encourage advancement of this promising field, NJIT, with funding from the National Science Foundation, has established a $3 million Geoenvironmental Engineering Laboratory.

This laboratory serves as a prototype for experimental facilities to be developed nationwide. NJIT is ideally suited to advance geoenvironmental engineering efforts. Interdisciplinary faculty bring broad research and industrial expertise to bear in the laboratory, the classroom and in collaboration with partners from industry and the public sector. NJIT is home to the largest industry/university collaborative hazardous substance research and pollution prevention center in the nation and has been recognized for its ability to find common ground among the private sector, academe and regulatory agencies. The university's location in a region with significant environmental needs heightens the awareness of researchers to the real and pressing issues the field addresses. The Geoenvironmental Engineering Laboratory, closely associated with NJIT's Center for Environmental Engineering and Science, offers industry access to researchers, students and state-of-the-art facilities.

Remote Sensing / GIS Laboratory

The Remote Sensing / Geographic Information System Laboratory has been established at NJIT with support from the National Science Foundation. This laboratory emphasizes environmental monitoring and management by integrating Remote Sensing/GIS technology. The RS/GIS Lab is interdisciplinary and will be unique in combining capabilities in civil, environmental, geology and surveying/mapping courses. It is a modern, state-of-the-art image interpretation facility with softcopy photogrammetry and GIS modules.
