In Kansas City, Kansas, Public Works’ Street Division uses both of the City’s Hot Patchers and the traditional “Throw and Roll” cold patching methods.
With onboard attachments like a jackhammer and tack oil application wand, the Hot Patchers allow team members to apply long-lasting and more uniform repairs to road surfaces. While this process is initially slower than the "throw and roll," repairs last much longer – in some cases until the next overlay or rebuild. Over time, the need to patch the same hole time and time again diminishes significantly. Team members do still occasionally use older patching methods to get material in troublesome holes and buy time until the Hot Patchers or surface treatments are available.
In 2021, Public Works added a brand new Crack Sealing machine to its street maintenance toolkit. Pavement expands and contracts as it cools and warms throughout the year. In some cases, this can cause cracks to appear on the streets. If these cracks are not addressed quickly, they allow moisture to sneak into the road’s surface and ultimately decrease the road’s overall lifespan. The new Crack Sealer allows teams to apply repairs quickly and efficiently, which aids Public Works significantly in their effort to stretch limited dollars further and keep roads healthier, longer. Unique to this model is its onboard and completely self-contained Asphalt Crack Sealing Kettle, which makes it capable of heating, melting, and applying all grades of rubberized asphalt crack sealer, joint sealants, and waterproofing compounds without the need for additional equipment.
