  • Patent number: 9132570
    Abstract: An apparatus for preparing a hot mix including aggregate and bitumen includes a cylindrical vessel incorporating a mixing chamber having a rotating paddle assembly mixing aggregate and bitumen. A heating chamber is below the mixing chamber, separated by a dome shaped separating element, the center of which is above its periphery. The heating chamber's lower part has a diameter less than that of its upper part. A blower forces air into the lower part through a horizontal passage with a burner heating the air. The axis of the passage is offset from the vertical axis of the heating chamber. The heated air spirals upwardly and outwardly through the lower and upper parts of the heating chamber, traversing the separating element before exiting through apertures about the periphery of the separating element. The mix is heated by the heat transferred from the air as it passes over the separating element.

  • Publication number: 20150139727
    Abstract: An infrared asphalt heating and repair apparatus includes a converter having downward facing slits cut therein to provide enhanced durability over prior art ceramic blanket or metal ribbon style heaters. In embodiments, the slits are cut by a milling machine, which may be an automatic milling machine, a band saw, or a laser. Embodiments also provide for more uniform heating over prior art solutions, while largely preventing damaging and costly flame-through events. Because the heat is more uniform than that of the prior art, lower temperatures can be used to achieve similar results, thereby extending equipment life, lowering fuel costs, and reducing warm-up times.

  • Publication number: 20120087726
    Abstract: In electrically heated screed assemblies, elements that are prone to failure are the temperature sensors. Typically, each screed plate has a single temperature sensor. When one temperature sensor fails, the controller will look for a working temperature sensor amongst the other screed plates and if more than one temperature sensor is working, the controller will choose the most relevant temperature sensor and use the data from the working temperature sensor to operate the resistive heating elements on the screed plate with the non-functional temperature sensor. If the temperature sensor on an outer screed plate fails, the controller will look to the other outer screed plate temperature sensor for data for purposes of operating the resistive heating elements on the outer screed plate with a broken temperature sensor.

  • Patent number: 7874763
    Abstract: A heating head for a paving apparatus includes a substantially cylindrical head housing, having a top housing edge axially spaced from a bottom housing edge, a sidewall having a spiral cross-sectional shape and a laterally extending top housing cover attached to at least a portion of the top housing edge. The head housing defines an air chamber and is adapted to accept and direct airflow through the heating head. The sidewall defines an intake vent at a radially outward end and an air chamber inlet at a radially inward end. The intake vent and air chamber inlet are spaced apart and in mutual fluid communication via an elongated circumferentially extending air passage to direct airflow from an exterior of the heating head to the air chamber.

  • Patent number: 7712999
    Abstract: A method and apparatus for drying soil wherein a soil drying machine is adapted to traverse an area of soil and to dry the soil in the process. The soil drying machine includes a main frame having an air generating device, such as a blower, and a heater mounted thereon. A system of heated air is generated on the soil drying machine and directed downwardly into engagement with the soil being dried. Forming a part of the soil drying machine is a tilling implement. From time-to-time the tilling implement can be lowered and engaged with the soil so as to till the soil prior to the soil being subjected to the heated air, or after the soil has been subjected to the heated air. The soil drying machine may be in the form of a self-propelled unit or a pull-type unit configured to be pulled by a tractor.

  • Publication number: 20100104363
    Abstract: A primary furnace device is adapted to heat a paved area to a first predetermined temperature. A secondary furnace device is adapted to heat the paved area to a second predetermined temperature via a multi-stage process having at least two heating zones interspersed with at least one soaking zone. A heater/shaver is adapted to heat the paved area to a third predetermined temperature and to shave the heated paved area to a predetermined depth to create a first mixture located upon a substrate. A mixer/finisher is adapted to collect the first mixture, mix the first mixture, and produce recycled pavement. The primary furnace device, secondary furnace device, heater/shaver, and mixer/finisher travel in series along the paved area in a longitudinal direction. A method of recycling pavement is also provided.

  • Patent number: 7674068
    Abstract: The cement finishing machine (10) has adjustable heat generating assemblies (22, 24), affixed to each side of the finishing machine (10). Each of the heat generating assemblies (22, 24) includes a propane burner that extends into an elongate heating tube. The heat generating assemblies (22, 24) also include a vertical adjustment assembly and detachable heat guards. The heat generated by the propane burner is directed through an opening in the bottom of each of the heating tubes and onto the surface of an unfinished cement slab during the cement finishing process. The heat facilitates the evaporation of excess water generated during the cement finishing process.
