Choose the right setup for your project and budget

Topcon asphalt paver systems give you the flexibility to set up your paver to meet your project’s demands. Choose from entry-level systems that follow a reference, such as a string or a curb; or automated solutions that track your paver in 3D and lay a variable-thickness mat for ultimate road smoothness. 

Variable thickness paving: smooth out the rough spots

In an ideal world, you would always lay down a blacktop on a perfectly milled or distributed base layer. Waves, drop-offs, potholes, and other conditions can cause a very different reality. Setting your screed to a fixed depth in these scenarios could allow these imperfections to “show through” even after the surface is repaved.

Variable thickness paving automatically averages the paver’s screed height to the high and low points for a smoother road with a longer projected lifespan. This technique provides a better driving experience and helps you meet DOT-mandated smoothness standards.

Pave with automated 3D guidance

Our traditional 3D paving systems use Millimetre GPS or robotic total stations to position and report the machine’s location and height. This reduces reliance on string lines or other references and accelerates the paving process. These control systems maintain a constant height accuracy of a few millimetres all day long. In addition, 3D paving tends to ease the downstream burdens on compacting teams.

Follow a fixed reference for 2D paving

Our 2D paving systems use sonic trackers to follow string lines, existing surfaces, or curbs. Mill and fill (also known as mill and overlay) projects, where pavers are laying tarmac on relatively flat base layers, are good uses of this technology.

Thermal Mapper reduces asphalt failures

The Thermal Mapper monitors asphalt temperature during the paving process to identify thermal segregation issues while they can still be corrected. This real-time capturing provides valuable information for compaction and documents the paving quality both internally and towards the ordering party.

Establish a level foundation with SmoothRide for RD-MC

Smooth road surfaces start with a solid plan for paving efforts. Scans at traffic speed are the first step in the SmoothRide road resurfacing process. Millions of points of scan data are used to depict accurate as-built data, provide estimates, and create the design for the variable-depth milling or variable-thickness paving phases of your road construction project. The correct milling depth or paving height is determined by calculating the difference between the as-built model and the design. Only the horizontal positioning is done via GNSS. This eliminates the need for optical components and, accordingly, a lot of side work. In areas without sufficient GNSS coverage, horizontal positioning can be performed by a total station.

Virtual Ski dramatically cuts design time

Virtual Ski is made for federal and country roads and other scenarios where there are fewer fixed points or intersections to match. Simply scan and mill or lay the base layer and let the milling machine or the paver do the surface design job. Our 3D-MC milling/paving software lets you replace analogue Multiplex-Ski, Big Ski, or Sonic Ski models and offset the Virtual Ski from 4 to 100 m off your chosen alignment, even on sharp curves. This results in a reduction of ski installation downtime; production of a smooth surface more quickly with less effort; and significant time savings, thanks to eliminated design activities.
