This three-part research project examined three different sets of technologies ? energy-absorbing fender systems, pre-cast or prefabricated bridge deck systems, report presents the findings and 'smart bridges' ? and provided recommendations for how New Jersey DOT should proceed with implementing them.
<p>Presently in work zones, standard barricade warning lights are used to provide channelizing and warning functions. These yellow flashing lights are presently used without consideration of the specific work zone activities underway at any given time.
<p>Barricade warning lights have been used for many years at construction sites to indicate to drivers that caution is needed. A benefit of these warning lights is that they are widely recognized and understood, but a downside is that "caution" is the only message that they are able to communicate. Drivers may not know what action should be taken until additional information is available, or it is too late.
<p>Fiber-reinforced polymer composites represent an alternative construction material without many of the performance disadvantages of traditional materials. The use of fiber-reinforced polymer as a pile material can eliminate deterioration problems of conventional piling materials in waterfront environments and aggressive soils. This paper presents the preliminary results of an experimental study conducted to assess the durability of piling made of recycled plastics in aggressive soils for long-term usage in civil infrastructure applications.
