Concrete dowel drilling systems can face tough construction
Posted: Thu Jun 08, 2017 9:44 am<P>Nebraska Highway 92 in the US stretches from Nebraska’s western border with Wyoming to Omaha where the highway leaves Nebraska and enters Iowa,<a href="http://maintenancemachineprice.com//crack-repair/equipments-required-for-construction.html">equipments required for construction</a> taking motorists through farmland and several towns and counties across the state. It’s also a major roadway that branches off from Interstate 80 and leads motorists through Polk County, Nebraska, where a recently completed road project is enhancing safety for motorists.</P>
<P>The entire project included diamond grinding the surface of the road, replacing areas of the road that had suffered excessive wear, and paving the highway’s earth shoulders which required over 40,000 dowelling holes that had to be spaced twice as far apart than normal.In May 2013,<a href="http://maintenancemachineprice.com//crack-repair/types-of-emergency-lights.html">types of emergency lights</a> the Nebraska Department of Roads (NDOR) initiated the resurfacing, restoration and refurbishing project. In addition to making the roadway safer, the project was intended to reduce maintenance
costs associated with maintaining the highway’s earth shoulder. The NDOR awarded the concrete
work to Palmyra, Missouri-based Chester Bross Construction, which was ready with its fleet of E-Z Drill pneumatic concrete drills.</P>
<P>The Polk County project replaced 34.76kms of the earth shoulder with concrete and increased the width of each lane to 3.65m to provide adequate stable area for tractors and increase safety for everyone on the road. Chester Bross Construction also replaced 4,537m² of road surface.<a href="http://maintenancemachineprice.com//crack-repair/profession-asphalt-pavement-repair.html">profession asphalt pavement repair</a></P>
<P>The crew had to perform the grading, culvert, paving and guardrail work within 160 days. And all that new concrete meant a lot of tie bars and a lot of dowel drilling. The Chester Bross crew of 16 had to drill a total of 40,492 holes, 22.86cms deep, to tie 45.72cm rebar into the existing concrete. Also,<a href="http://maintenancemachineprice.com//crack-repair/commercial-grade-asphalt-sealer.html">commercial grade asphalt sealer</a> because the shoulder is far less travelled than the main roadway, it required less reinforcement from tie bars, so holes could be spaced every83.82cm, 53.34cm wider than typical roadway projects. While this reduced costs and the number of holes by 65,000, it created a challenge for Chester Bross Construction – the company’s drills could only achieve a maximum of 76.2cm spacing.</P>
