The Non-Contacting Alternative To Mechanical Ski Averaging.

When you want the superior averaging of a ski in an easy-to-use system that allows continuous work throughout the day, the choice is clear. Look to Topcon for Smoothtrac®, the world's only non-contacting grade averaging system.

Smoothtrac® features include:

• Non-contacting grade averaging system
• Improved machine mobility
• Seamless addition to your existing Paver System Four or Five

Smoothtrac® works with Topcon's innovative Paver System Five automatic control system to improve mat smoothness in record time. Up to four Sonic Tracker IIs™ mount onto the non-contacting ski and provide grade information to the operator. There's no more stopping to clean or reposition a ski because Smoothtrac® mounts onto the side of the paver and works above the surface. You're free to work continuously from start to finish, saving time and money!

Unlike problematic mechanical skis that just can't handle curved roads, Smoothtrac® offers the advantage of unparalleled maneuverability. Back up for the next pass, turn around, or pave miles of curved road worry-free.

You might think an averaging system that sounds this good is hard to set up, but with Smoothtrac®, the lightweight aluminum ski requires just minutes to install. Or if you need it out of the way after setup, hinged section joints let you fold the Smoothtrac® ski down to 1/3 its size without ever taking it off the machine. And when it's time to tear it down, Smoothtrac® separates into three sections that fit into a standard truck bed!
