Infrared Asphalt Joint Heating System

The most effective method of bonding asphalt paving joints.

This System has been designed to eliminate cold-joint and density problems that arise with longitudinal asphalt paving joints.

The pre-heating units work with the paver mounted unit to provide a dependable system that can be adjusted to most paving conditions.

The fully automatic heating system not only protects against overheating of the pavement, it also provides for easy operation and consistently reliable results. It’s Like Having No Joint At All.

At Smart Fix Asphalt, we take pride in utilizing the most efficient road maintenance equipment. The Smart Fix Asphalt Joint Heating System employs our many years of experience with infrared technology. In using our proven Smart Fix Asphalt Infrared converters in the system, we bring to the asphalt paving industry a means of eliminating a problem that is as old as the industry itself. Cold Joint Bonding. The cold joint has been consistently the weakest and most troublesome part of the pavement. Being predisposed to failure when combined with the poorly compacted joint area of the previously laid pass, it is our goal to develop, produce and provide equipment capable of counteracting this problem.

SPECIFICATIONS GENERAL: The machine design is to provide an infrared heating system capable of heating longitudinal joints without burning or damaging the asphalt. This system will heat the longitudinal joint immediately before the adjoining asphalt is laid, in order to achieve adequate bonding and compaction along the longitudinal joint. The system is designed to be fully automatic, with the automatic controls turning the units on or off as needed. The system is nominally composed of up to five Pre-Heaters and/or three Reflector units and one Paver-Mounted heater. The number of Pre-Heaters/ Reflectors are determined by the paving conditions. The Pre-Heaters/Reflectors are towed ahead of the paver, while the Paver-Mounted Heater is attached to the paver. Tracking of the Pre- Heaters/Reflector units are by a Center Wheel Steer Tracking System.

INFRARED HEATER: The infrared effect is created by pre-mixed gas and air delivered under pressure to a series of energy converters. Infrared does not flame or negatively alter the binding characteristics of asphalt. Each Heater Unit contains a heating chamber, measuring 15″ x 144″, which is designed to be operated in a horizontal position, and which will have a maximum propane consumption of 1.333 lbs. per square foot, or 28,660 BTU per square foot per hour. This corresponds to 20 pounds of propane per hour for each heater. The chamber is constructed of 16- gauge stainless steel, which is properly vented with stainless steel louvers

FUEL: Is delivered by vapor withdrawal propane cylinders. The Pre- Heaters are fed by four (4) 100 lb. horizontal propane cylinders carried on the Pre-Heater chassis (supplied with the unit). Fuel is delivered via high-pressure gas lines through a strainer to a regulator, where it is reduced to 11″ water column pressure, then through a solenoid safety valve. After this, a limiting orifice valve controls the gas flow before being delivered to a 115 volt AC long life brushless motor/blower mixer system. The paver-mounted heater is fed by six (6) 30 lb. cylinders.

OPERATING CONTROLS: The operating controls consist of a threeway switch, with the following options: Off, Automatic, and Manual override. The Manual override position allows the unit to be on continuously. The heaters incorporate a fail-safe ignition system, which turns off the gas flow to the heater if proper ignition is not detected. An infrared optical sensor insures accurate temperature control with a minimum of maintenance. On both paver mounted heater and pre-heaters, the automatic setting keeps the heater on as long as the temperature of the asphalt is less than the predetermined sensor setting

CONVERTERS: The thirty-six inch energy converters are constructed of 16-gauge stainless steel for long production life. The nickel alloy grids that produce the infrared rays are located in the center of the converters. These rays are directed to the pavement through the use of stainless steel reflectors.

HEIGHT ADJUSTMENT: Chamber on the preheater is designed for quick and easy height adjustment.

POWER REQUIREMENTS: Units are powered by a 115 volt AC propane powered generator with a capacity of 20 amps for each. Generators are included with the pre-heaters. Generators are not included with the paver-mounted heater, which takes power off the paver.

ATTACHMENT: The pre-heaters attach to a 2.5″ ball on the tow vehicle. The pre-heaters can attach to each other and can accommodate a trailer ball height of 12″ maximum. The pavermounted heater is supplied with two (2) adjustable pipe brackets that attach to the paver. The paver-mounted heater is attached to these adjustable brackets for fast mounting and dismounting of unit.
