          Excavating, whichhas been contracted to

          of overburden for
        
        
          a road construction project close to the
        
        
          town ofMacomb in Illinois, US.
        
        
          The Route 336 project, valued at
        
        
          US$ 32millionwas awarded to Bloomsdale in July last year by
        
        
          the IllinoisDepartment ofTransportation (IDOT) and includes
        
        
          building 6.5 miles (10.5 km) of a four lane highway on US
        
        
          Routes 336 and 110.The project will require pre-grading work
        
        
          and the construction of drainage structures on a new section
        
        
          of the roads, as well as the reconstruction of county highway
        
        
          14, which is located to the west of Macomb. It also includes
        
        
          10 miles (16 km) of grading and clearing, and the installation
        
        
          of utilities.
        
        
          There are 48 machines on site, including 22 Volvo A40F
        
        
          articulated dump trucks (ADTs), 13 with the company’s Full
        
        
          Suspension (FS) system and nine with standard suspension.
        
        
          Bloomsdale is using the FS units with a 25.2m
        
        
          3
        
        
          scrapers from
        
        
          K-Tec Earthmovers to move loose dirt. The company uses its
        
        
          standard units for other tasks, such as rock hauling.
        
        
          The FS system cushions the impact of the K-Tec hitch and
        
        
          the automatic cushion ride on the scraper itself makes for a
        
        
          formidable combination in terms of speed, operator comfort
        
        
          and productivity – while minimising the risk of equipment
        
        
          damage.
        
        
          Scott Drury, president of Bloomsdale Excavating, said he
        
        
          was pleased with the combination, “Productivity on site has
        
        
          increased as the machines never need to stop. Our operators
        
        
          work 10 hour shifts and the Volvo haulers clock about 2,000
        
        
          hours on average a year,” he said.
        
        
          This all goes to show that whether the road project is concrete
        
        
          or asphalt, or whether it is in the paving or earthmoving
        
        
          stage, equipment manufacturers have a lot to offer that can
        
        
          shorten project timelines, cut costs and improve efficiency and
        
        
          productivity.
