Concrete milling, paving & compaction

Provo, Utah – The scope of the I-15 Corridor Expansion Project (I-15 CORE) in the state of Utah is nearly unprecedented because of the size of the project and the short completion deadline. Twenty-four miles (38.6 km) of removal and replacement of Interstate 15 between Lehi and Spanish Fork, widening the number of traveling lanes by two, for up to six lanes in each direction in 35 months. The new 364 lane miles (586 km) of concrete roadway will be slipformed 12 or 12.5 inches (305 or 318 mm) thick for a tot

In the Southern German state of Bavaria a contractor is using an adapted machine from Sennebogen for concrete paving duties. Munich-based Heilit+Woerner is using the Sennebogen machine as a carrier vehicle for applying bases for road surfaces. Sennebogen supplied one of its SR 25T models as a carrier vehicle for a new road base finisher. The multifunctional device is now used with a paving screed for bound and unbound road bases and allows the contractor to combine stages of work in one. The material can be

To meet a need to carry out complex modern bridge designs, the Terex Bid-Well 3600 paver is available with truss transition inserts, increasing maximum paving width from 27.4-33.5m. The inserts adjust truss depth from 914-1219mm toward the paver’s centre, reducing frame deflection and this is said to increase surface profile smoothness. Offering paving widths from 4.6-33.5m with optional transition inserts, the 3600 gives companies more versatility for paving a wide variety of bridge designs, including mult

In the Philippines, a GOMACO GP-2400 concrete paver has been carrying out slipforming work on a project that will help alleviate traffic congestion. CM Pancho Construction Company, based out of Quezon City, Philippines, recently purchased a new GOMACO GP-2400 two-track paver. The firm had previously owned a GOMACO GT-6300 and made the decision to upgrade to a new machine, receiving the new unit earlier this year. The company put its new GP-2400 to work immediately on the Plaridel Bypass Road project near th

Allen Engineering has developed the new RS844 roller screed model with improved performance. The unit can be used for highway panel replacements, white-topping or airfield upgrades and is said to be a cost effective tool. The RS844 is the first of the new series of Allen spinning tube pavers and is a ride-on steerable roller screed powered by a 33kW Kubota diesel making it the most powerful roller screed on the market. The 203mm diameter paving tube is said to provide 25% more surface contact to the concret

Dan Gilkes reports on a Belgian highway upgrade When the Ministry of Public Works in the Belgian State of Flanders decided to reconstruct and resurface 19km of the N49 Antwerp-Knokke Expressway, continuously reinforced concrete paving (CRCP) with an exposed aggregate surface was the natural material choice. Indeed exposed aggregate, with its high grip and low noise benefits, has been the first option for all motorway surfacing work in Belgium since the 1980s. However, the €15.65 million contract is not a li

The country of Qatar, located on the Persian Gulf, developed a master plan to build a new replacement airport in its capital city of Doha, the New Doha International Airport, in 2003. Its goal is to have a facility capable of handling 50 million passengers; two million tons (1.8million tonnes) of cargo, and 320,000 aircraft landings and take-offs each year by 2015. Phase one of the aggressive project is scheduled for completion early next year. The Tayseeir Contractors Company Joint Venture, including Conso

A major expansion programme is underway at King Abdulaziz International Airport in Jeddah, Saudi Arabia. The work started in the third quarter of 2006 and is due for completion in 2015, with the construction activity being carried out in three main stages. Once the work is complete the airport will be able to handle up to 80 million passengers/ year, compared with 13 million/year before construction commenced. The project also includes three new terminal buildings and a high-speed rail link, as well as airf

In Kansas, specialist contractor Pavers has carried out important work for the National Guard. The aim of the work was to rehabilitate a WWII era hangar apron for the Kansas National Guard. The project required extensive repair work, including pavement patching, dowel bar retrofitting, partial depth patching and joint sealing. Pavers had to overhaul a 305m x 91.5m apron at Army Aviation Support Facility No 2 that suffered from poor drainage. The project included milling 152mm of old asphalt and concrete and
