Astec SmartEdge Tech Enhances Precision Joint Matching

Astec Industries, Chattanooga, launched its SmartEdge™ joint detection technology for use on its F-Series pavers in 2024 and showcased the new technology during World of Asphalt 2025 in St. Louis. The SmartEdge is a screed automation technology designed to allow the paver and screed operator to precisely follow any concrete or asphalt vertical edge during paving. The endgate attachment achieves precision joint matching by sensing the lane edge with a laser sensor. It sends that information from the sensor unit to a control head unit at the operator’s station. The operator sets the parameters using touchscreen controls, then the SmartEdge sensor monitors the edge for the correct overlap while paving and automatically creating a path for the screed extension to follow. The technology fine-tunes the path as the machine paves forward.

The SmartEdge system consists of a lane edge sensor utilizing laser technology and a control head unit with touchscreen. An operator uses the control head touchscreen to set edge parameters to meet the job’s specifications. The control head unit then uses this information to automatically create a flight path for the screed endgate to follow.
