Using Mechanical Ice Breakers to Improve Snow and Ice Removal Operations

An extensive body of work exists regarding the utilization of mechanical ice breaking technologies which have been specifically developed to effectively cut through ice pack bonded to highway pavement surfaces. The ideal performance objective is the ability to mechanically scrape down to bare pavement with little or no damage to pavement and without waiting for a salt treatment to soften a layer of bonded ice before effective removal can be achieved. Attaining this capability implicitly delivers an associated reduction in highway salt usage and more quickly provides motorists with the higher level of service and safety bare pavement provides. The diversity of ice breaking technologies under development does not appear to be converging on a single best solution, but instead is increasingly becoming tailored to the distinctive needs and weather conditions of the individual State DOTs. The list of mechanical ice breaking technologies, which have been DOT-proven as efficient at cutting through ice pack on the highway, are categorized and ordered based on their apparent adaptability to the existing Caltrans winter operations fleet.
