Abstract: Traffic plates are traditionally used to temporarily cover open excavations in roadways and walkways. Most often these plates are fabricated from 1-inch thick steel plate, weighing up to several thousand pounds. Because of the weight, heavy construction equipment, such as a backhoe or bulldozer, is required to maneuver the plates into position at night and remove them the following morning. This results in the additional expense of diverting the construction equipment (0 he job site along with the associated delay lime before the gas crew can begin work. A new lightweight plastic traffic plate has successfully completed two years of field trials at Consolidated Edison Co. of New York. These plates are both light enough to be manually maneuvered on the job site and strong enough to be positioned over street and sidewalk openings. The plates are available in various sizes ranging from 4-fool x 4-foot to 5-foot X 10-foot and weigh less than 15% of the steel plates.
