Quick Overview:

  • Trailer mounted that is ideal for medium crews
  • Diesel fired melter with heated hose and wand
  • Stainless steel fire tube baffle system


Need a quality built melter for filling cracks in parking lots, streets, roads, or highways?

The A500CDT is a diesel-fired crack sealing trailer that is perfect for large government maintenance departments or commercial crews who need a great highway asphalt crack filler trailer.

Included is a 25' flexible, 120V electric heated, jacketed hose that is attached to a 360º swivel boom for full coverage around the machine and a heated applicator wand.  (Longer option hose available)

The 120V electric hose system is powered from an included gas-powered generator that is also attached to the trailer.  (An optional diesel generator is available for a pretty hefty price)

The A-500CDT is run off of a Yanmar 7.0HP diesel engine that powers a 2" VIKING material pump which includes the pully's, belts, and guards.

The kettle is heated using a Becket diesel burner system with an included automatic temperature control system.  The flame is sent through 4" SCH-80 stainless steel fire tubes which heat the kettle fast and will add years to the overall durability of this crack sealing trailer.

The trailer is made with heavy-duty, 4” channel steel with 14” tires/rims and includes wheel fenders, lights, 2” ball-hitch, and trailer jack.

With an overall efficiency of 78.9%, the A-500CDT only takes around 35 minutes to fully heat 100 gallons and can heat approximately 136 gallons per hour.

Build & Delivery Note: These systems are built from scratch upon ordering.  Please allow 5-7 weeks for build time and 7-10 business days for shipping.

Air Jacketed vs Oil Jacketed

If you've been searching for trailer mounted crack sealing machines, chances are you've run across units that are advertised as being oil-jacketed units.

The main difference between an air-jacketed kettle and an oil-jacketed kettle is the medium that is heated and transfers heat into the kettle.  Both types of melters usually are constructed as a double-wall kettle where oil-jacketed heats oil to transfer heat and air-jacketed heats air to transfer the heat.

For a better explanation, check out our info article on the difference between Direct Fire, Air Jacketed and Oil Jacketed melters.

Propane vs Diesel

The A-Line of crack melting trailers are made with two main fuel options: Propane or Diesel

Which should you buy?  The decision comes down to two factors.

Fuel Availability

If propane is easier to get ahold of, go with the propane.  If diesel is easier, go with diesel.  As far as fuel availability goes, it's that simple.


If fuel is easy to get ahold of, the next decision to consider is the complexity of the system.

Propane: The propane system is very straight forward with very little that can go wrong.  Outside of needing a new burner or a few other minor items, the propane fuel system is the easiest and cheapest to maintain.

Diesel: The diesel system, in contrast, is a lot more complex of a system.  If you need diesel and don't mind knowing that there is a little more to it, then diesel is a fantastic route.  That said, there is a lot less maintenance with the A-series diesel units when compared oil-jacketed melters.

Which Rubber To Buy?

If you've been in the crack filling industry for a while, you probably know that there is direct-fire rubber and oil-jacketed rubber.  In the early days of the industry, the only type of rubber that was manufactured was to be used in an oil-jacketed melter.  In those days, they were easier to control the temperature.  Fast forward 60+ years, we have thermostats and automatic temperature controls do all of the heavy lifting to maintain a consistent and accurate temperature.

What that means for you, is that you can rest-assured that a rubber advertised as an oil-jacketed material will work just as well in the A-Line of crack sealing melter trailers.  We have contacted our rubber manufacturer and they have assured us that oil-jacketed rubbers will work in any melter that has adequate agitation and doesn't create "hot spots" where the rubber can over-heat.  The A-Line melters are designed around both of these problems and have been tested to work perfectly with oil-jacketed rubbers.
