Advantages and Features

Application Versatility

        
  • Common applications include urban and rural roads, streets, air-ports, highways, and interstates
    •     
  • The standard paving range of 2.55 m - 5.0 m (8' 4" - 16' 4") provides excellent performance when changing paving widths for both urban and highway paving applications
    •     
  • Simple, bolt-on extensions offer a maximum paving width of 7.64 m (25')

Pave Start Assistant

        
  • Pave Start Assistant saves set-up profiles for repeatable use on future job sites, simply activate the profile for quick, single person setup
    •     
  • Set-up preferences include: tamper speed, tow-point height, screed heat temperature, paving speed, paving width, paving depth, crown, extender height (power option), screed assist, and screed locking features
    •     
  • Setup features are located in the left screed display and can also be viewed through right screed display and tractor displays

Simple Operation

        
  • Operating displays can be tailored to specific language requirements with multiple options available
    •     
  • Exclusive 2-speed, proportional extender control provides smooth adjustment when transitioning paving widths
    •     
  • Screed operating consoles are equipped with ratio adjustment for the augers and conveyors, providing the ability to modify material flow
    •     
  • Optional power controls for extension height enables operators to quickly manage mat quality
    •     
  • Trailing edge screed plate adjusters help maintain an even plane across the width of the screed in order to enhance paving quality and extend screed plate life

Smooth Material Flow

        
  • Enhanced tamper-bar and deflector plate profiles provide smooth flow to the screed plates
    •     
  • Screed plate depths of 324 mm (12.75") on both the main and extenders provide stability and good mat textures
    •     
  • The heated end gate option helps prevent material from sticking for better edge profiles and joint matching capability

Quick Heat, Even Distribution

        
  • Belt-driven, tractor mounted generator delivers fast heating screed plates for quick starts
    •     
  • Electric heating system with zone monitoring helps ensure even heat distribution and smooth asphalt textures while also allowing heating to continue in the event of a temperature sensor failure

Cat Grade Control (Option)

        
  • Factory-integrated leveling system that helps remove irregularities from the surface and control mat thickness for increased production, lower operating costs, and higher profitability
    •     
  • User-friendly system with text-based displays, split screen-mode, and on-the-go sensor selection
    •     
  • Precise control driven by 10-point auto-calibration, true averaging with 5 transducers in each sonic sensor, and cross-coupling feature that maintains slope requirements more consistently when changing elevation

Service Repair Kits

  • Paver and screed service and repair kits include the parts necessary to complete specific repairs
  • Cat genuine parts are manufactured to precise specifications and designed for optimal performance and maximum uptime
  • Repair kits are identified by a single part number to make ordering easy
  • Select kits are available to be packaged as a kit by the dealer for over the counter purchases or through the dealer service shop
