Wed August 10, 2022 - National Edition Wirtgen

Apart from the SP 15(i) and SP 20(i) offset pavers at this year's bauma, Wirtgen also is showing a complete paving train for fully reinforced concrete paving. This comprises a WPS 102(i) placer/spreader, an SP 94(i) inset paver, and a TCM 180(i) texture curing machine.

Also making an appearance at the show is an SP 124(i) with a new, integrated dowel bar inserter.

All compatible machines at the show also will feature Wirtgen's own, specially developed, AutoPilot 2.0 control system for stringless paving.

The production of concrete safety barriers with a height of up to 6.5 ft. and the paving of flat surfaces with widths of up to 8.2 ft. are typical applications for the SP 20(i) offset paver. With the new machine, Wirtgen offers its customers an ideal combination of productivity and mobility, according to the manufacturer. Despite the large paving widths and heights it offers, the machine has a low transport weight and compact dimensions.

The compact SP 15(i) has been delivering outstanding performance in a wide range of application scenarios around the world for many years. In Munich, it is fitted with a "Curb Depressor Mold", which enables automated paving of lowered curb profiles, as are often found on driveways. The paving process can proceed without interruption and the need for manual reworking is significantly reduced.

In the case of the inset pavers, Wirtgen is showing a train of three perfectly coordinated machines for the paving of high quality concrete traffic infrastructure. All three feature concrete paving equipment with the Imperial dimensions typical for the U.S. market.

The paving train is set up for a working width of 24 ft. A placer/spreader such as the WPS 102(i) generally comes into play when paving over pre-placed steel rebar. It travels in front of the slipform paver over the pre-placed steel rebar, while concrete is fed to the belt conveyor swung out from the side from a concrete mixer or a tipper truck.

The concrete is poured evenly over the pre-placed steel rebar in front of the slipform paver and distributed across the entire working width. The SP 94(i) slipform paver then compacts and paves the concrete mix.

The paver at the show, which has a maximum working width of 32 ft., is fitted with a TeleMold system. It enables fast and convenient alteration of the working width by up to 3 ft. on each side, resulting in an overall increase of 6 ft. This increases the flexibility and productive utilization time of the machine by the reduction of down times.

The final link in the process chain is the TCM 180(i). This field-proven texture curing machine applies the desired finish to the surface of the freshly paved concrete. It enables the realization of lengthwise and crosswise textures and pre-defined surface roughness in accordance with project specifications. It also allows the application of a range of different curing agents to the concrete surface, for example a concrete surface retarder.

A 24-ft. paving train, comprising a WPS 102(i), an SP 94(i) with a TeleMold system and a TCM 180(i), offers the entire range of options available for fully reinforced concrete paving. SP 124(i)

A 24-ft. paving train, comprising a WPS 102(i), an SP 94(i) with a TeleMold system and a TCM 180(i), offers the entire range of options available for fully reinforced concrete paving.

The largest slipform paver on show at this year's Bauma is the SP 124(i). The 4-track paver can be configured for paving at a working width of 39 ft. and fits seamlessly into the fleet-wide operating concept of slipform pavers from WIRTGEN.

The machine is fitted with the latest generation of the integrated dowel bar inserter. The dowel bars are extracted from the magazine by a chain feed system with an endless chain and automatically transported to the insertion location.

"Smart" cylinders with displacement sensors precisely position the dowel bar inserter at the desired locations. The high degree of automation reduces the proportion of manual work required, increases process reliability, and, ultimately, the cost-effectiveness of the process.

Developed in-house by Wirtgen, AutoPilot 2.0 is a control system for stringless paving that serves as an alternative to the conventional method of mechanically scanning a stringline. The system, which precisely controls both the height adjustment and steering of the machine, is available for all offset pavers and placer/spreaders.

A GNSS signal and, depending on the configuration, various local sensors (e.g. an ultrasonic sensor on the machine), serve as a reference. The time and effort otherwise required for setting up and removing the stringline is eliminated. It also enables fast and precise paving of tight radii and complex geometries.

The system is conveniently operable from a tablet PC, which also supports the generation and editing of terrain models. Wirtgen AutoPilot 2.0 offers machine control and stringless control for concrete paving in one.
