The Automated Crack Sealing Machine (ACSM) was developed to identify and seal all types of highway pavement cracks. It was a self-contained vehicle that could both seal cracks entirely within a highway lane and seal longitudinal cracks alongside the vehicle.
The SHRP H107A Automated Crack Sealing Machine (ACSM) was fully operational in 1993 and could rout, hot blow and seal longitudinal and random cracks automatically. The ACSM completion had to coincide with the previously scheduled SHRP sunset and was then to be passed over to the Federal Highway Administration (FHWA) for implementation.
