A marriage of cold mill-style pavement cutting tools to a vibrating soil compactor has resulted in a roller that can cheaply shatter aged portland cement concrete (PCC) pavements, and may lead to a new era in pavement demolition and crack-and-seat reconstruction, according to the manufacturer.
Breaking of PCC pavements slated for removal has been done by time-consuming guillotine-style or percussive breakers, backhoes with breakers, dozers with rippers, or costly ultrasonic vibration by specialty contractors. These pavements would then be dug out to be landfilled or recycled, or the concrete chunks seated in place with rollers in advance of bituminous overlay.
Now demolition of concrete surfaces can become widely available to all with the new Hamm H 25i VC. This 25-ton (22.6 t), 214 hp, Tier IV interim emissions-compliant roller with 84-in. (213 cm) drum can crush rock and concrete in-place in one step, saving time and money while revolutionizing the process.
The “VC” in the model number stands for vibration crusher. The Hamm H 25i VC utilizes standard vibration to shatter concrete in-place, using its vibrating, tool-equipped drum to crush and break rock and concrete.
Its special toolholder system can accept a wide range of tailor-made point-attack tools designed for different situations. A total of 150 quick-change toolholders are welded to the drum for this purpose.
With the appropriate kit, the H 25i VC also can be converted to a padfoot roller.
