Overview
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.
