Stringless concrete paving systems are easy to use for contractors - Daniel C Brown. With just a few days of training, Hawkins Construction is now up and running with stringless concrete paving technology. This year Hawkins started using the stringless technology on two Interstate highway paving projects, with a total contract value of US$78 million. The projects were on I-80 between Omaha and Lincoln, Nebraska and the first section was for a 9.25km, 18.3m wide stretch of 330mm thick concrete pavement.
A Simex PL 2000 cold planer was recently used on the narrow streets of the Tuscan capital Florence in northern Italy. The project involved resurfacing the wearing course at a depth of 30mm, explained Andrea Palmerani, owner of contractor Bitumvie.
“We needed equipment that would guarantee us a large milling surface all the while remaining in the field of compact machines suitable for a city context,” he said. “The 2m-wide drum immediately attracted my attention.”
