TransTech has been working with many states and has developed a solution known as the Shoulder Wedge Maker™ (SWM). The TransTech SWM mounts directly on the paver screed extension against the end gate and provides a 30 beveled shoulder edge that gradually transitions wayward vehicles off shoulderless road surfaces and back on with relative ease.
An internal spring holds the Shoulder Wedge Maker™ down to the road surface while it, in combination with the compound angled face, encourages compaction as the mat is laid.
The compound angle of the wedge and extended surface also provides for a smoother finish. The SWM kit is delivered in a pair, with the right-hand version used on mainline paving in the direction of traffic and the lefthand available for divided highways, ramps and mainline paving against traffic which is typical in some jurisdictions.
The TransTech Shoulder Wedge Maker™ is easy-to-install and easy-to-use, offers a smooth finish and good durability and meets AAA recommended slope criteria.
