Here’s How It Works: Carlson’s CP75 Commercial Paver
Sometimes a highway class paver is too large to “slim down” for a parking lot or driveways. For such projects, Carlson Paving Products, Tacoma, Washington, introduces the CP75 to its commercial paving line. Here’s how it works.
First, a haul truck delivers mix in increments to the 8-ton hopper. The High Flow Material Conveyor in the floor of the hopper, which is made of dual heat-and oil-resistant belts fastened to chain driven slats, delivers the mix to the flow gates at the back of the hopper. The hybrid system moves material rather than dragging it, eliminating segregation of the mix in the process. The flow gates scrape the belt to prevent material from being carried to the undercarriage of the paver.
As the conveyor delivers the material to the back of the hopper, horizontally sliding damper doors and hardened 9.5-inch auger flights feed material to the screed.
Once the material is delivered to the screed, the asphalt comes into contact with the 450 Brinell-rated screed plates. Electric heating elements in direct contact with the upper surface of the main and extension screed plates keep the EZC813—or EZC815—screed heated. Spring-loaded endgates provide consistent ride of the screed and increase material containment.
At the back of the machine, the operator has full operation of the paver and the screed through screed-mounted controls and analog readouts, allowing for full monitoring of the engine and performance.
