Asphalt repairs made permanent

Two new Bobcat attachments improve asphalt repairs by recycling existing material, as well as minimizing manpower, creating a new eco-friendly solution for contractors and government agencies

Repairing asphalt surfaces is now more cost-effective and more permanent, thanks to new asphalt preservation tools from Bobcat Company. The system includes two new Bobcat® attachments aimed at improving the process of repairing asphalt surfaces.

The new asphalt preservation tools include the Bobcat AH30 asphalt heater and AP40 asphalt processor. Together, these attachments and a Bobcat loader provide a cost-effective method of repairing damaged asphalt pavement by seamlessly fusing recycled asphalt with the existing surrounding pavement. Contractors and government agencies can follow a simple four-step method to repair potholes and other surface defects such as cracks, deteriorating surfaces and frost heaves that develop in streets, highways and parking lots. The system can also be used to make repairs to asphalt driveways, trails and golf cart paths.

Bobcat asphalt preservation tools improve the process of repairing surfaces, with less manpower (only two crew members) and materials needed. Because of the compact size of the loader and attachments, the system can work within a single lane, minimizing traffic disruption. Additionally, only one adequately sized truck and trailer are required to transport the Bobcat loader, heater and processor.

The AH30 asphalt heater is powered by a 36 kVA generator and moved from repair to repair, using a Bobcat loader with the Bob-Tach® attachment mounting system. To get started, the heater is activated by pressing an on/off switch. Once it’s ready, it heats a 30-square-foot area using infrared heat, until it reaches approximately 300 degrees Fahrenheit. The heat softens the area without damaging the asphalt. Once the required temperature is reached, the loader operator moves the heater and attaches the AP40 asphalt processor.

AH30 specs

  • Weight: 3760 lb.*
  • Length: 59 in.
  • Height: 84.4 in.
  • Width: 111.4 in.
  • Repair area: 30 sq. ft.
  • *with full fuel tank

    Powered by the auxiliary hydraulics on a Bobcat loader, the AP40 asphalt processor mixes, processes and levels the asphalt surface to the desired depth. The AP40 has a direct drive motor with few moving parts for optimal performance. Similar to a tiller in soil, the processor’s tines mix the asphalt into a reusable material. This process is completed a few times, and the Bobcat loader operator uses the attachment’s skid wings to push material back to the middle and level it to prepare for compaction.

    AP40 specs

  • Weight: 995 lb.
  • Length: 60.4 in.
  • Height: 47.7 in.
  • Width: 76.9 in.
  • Cutting depth: 1.5 to 6 in.
  • Cutting width: 45.5 in.
  • Approved carriers

    Bobcat 700- and 800-frame-size loaders are approved for use with the AH30 and AP40 tools. For models other than an S850 or T870, a 400-pound counterweight kit is required.

    Additional items needed

    In addition to the AP40 processor and AH30 heater, the following items are needed to complete the asphalt repair process:
  • Asphalt rake
  • Infrared thermometer or metal probe
  • Liquid asphalt rejuvenator, available from Bobcat Parts
  • Walk-behind drum compactor
  • Reclaimed asphalt pavement (RAP)
  • Shovel
  • Eco-friendly

    The new Bobcat asphalt preservation system is an answer to a growing need for eco-friendly repairs. Existing asphalt can be reused onsite, rather than delivering expensive asphalt (hot mix) to the repair. This can save as much as 60 percent of the costs associated with conventional asphalt repair methods, eliminating the need to transport, process and stockpile raw materials. Also, the asphalt preservation tools package can be used in the harshest conditions, miles away from a batch plant, because it doesn't need hot mix asphalt.

    Asphalt preservation tools from Bobcat Company are just another example of how versatile Bobcat compact equipment is and how it can be operated to address a growing challenge — the aging asphalt that makes up approximately 94 percent of the more than 2 million miles of paved roads and highways in the United States.
