Mabey’s 300-foot interlocking roadway provides contractor stable ground to drive piles for bridge replacement.
General Contractor Kyle Conti Construction from Hillsborough, NJ, was working on the demo of the old Sunset Avenue Bridge and trying to determine the best way to drive the foundation piles into the lakebed. The contractor contacted Mabey to see if their inhouse engineers could design a temporary roadway to make the site safe for their crew and equipment but also aligned with the EPA and NJDOT regulations. Mabey delivered.
Mabey DuraBase® Mats. These mats are made from prefabricated composite material, each molded as a seamless, one-piece 8‘x14‘ mat. They also have a non-skid surface pattern that prevents slips and repels static. They are engineered to be flexible to conform to uneven terrain but strong enough to support a 120-ton crane. The contractor accepted Mabey’s roadway solution that consisted of 430 interlocking mats to create a 300-foot roadway. Since Mabey’s engineered matting system was designed to include work pads that branched off the roadway, it enabled the contractor to get closer to the piers than they originally planned by placing the cranes on the matting workpads.Back to top
The matting configuration allowed Kyle Conti to downgrade the need for a 150-ton crane to a 120-ton crane to do the same job, saving money and delivering less impact to the lakebed. The mats were in place until Kyle Conti was able to set the trusses with the crane. Then the mats were removed because the contractor was able to do the decking and rest of the bridge work from above the lakebed.
Mabey’s DuraBase® mats will not absorb water and can be easily cleaned to prevent cross contamination from site to site. Traditional wood mats absorb water, making them hard to remove once exposed to wet conditions and decontaminating a waterlogged wood mat is near impossible. Although the contractor had installed a dyke around the site to keep the riverbed dry, undeground river water still seeped in along with rain water that had to be continuously pumped out during the project. The composite mats got wet but did not get waterlogged so removal was easy.Back to top
