Percol: A Polyurethane System To Simplify Laying Of Buried Cable (1987)
By Jack E. Gieck, P.e. And Ransome J. Wyman, ARNCO
A liquid polyurethane system developed originally for rapid repair of bomb-damaged Air Force runways may simplify, expedite, and substantially reduce the cost of laying buried cable in urban streets and across highways, according to field tests conducted in a cooperative program between Prime Cable of Austin, Texas, Simpson & Sons, Las Vegas cable contractors, and ARNCO of South Gate, California, developer of the urethane system. Testing has demonstrated that highway traffic can be resumed in 30 minutes after coaxial cable is encapsulated in a (three-inch-wide by six inches deep) trench sawed into the pavement. When optimized, the system could represent a benefit of as much as $100,000,000 to the cable industry.
