A method for building a surface with an embedded tubular body includes applying a first layer of a first material to a first surface and applying a tubular body. The tubular body can be applied at a top surface of the first layer or the tubular body can be applied at a top surface or within the first surface.

A portable asphalt heater and method for heating asphalt includes an asphalt hopper having a floor, first and second side walls and front and rear end walls. The side walls taper inwardly to define a substantially inverted-V geometry of the hopper. A heating manifold including a heating chamber is adjacent to and positioned beneath the floor, the heating manifold adapted to be in fluid communication with a heater assembly and to direct a heated gas emitted from the heater assembly through the heating chamber and heating manifold. A plurality of chimneys is in fluid communication with, and extends from, the heating chamber and along the first and second side walls, wherein the volume of asphalt, when in the asphalt hopper, is heated through contact with the asphalt hopper.

The present invention relates to systems and methods for mixing various components of asphalt concrete in a mixer and then dispensing the asphalt concrete from the mixer. While the mixer can include any suitable component, in some instances, it includes a heated container, a mixing mechanism that is configured to mix asphalt and an aggregate to form the asphalt concrete within the heated container, and an auger that is configured to force the asphalt concrete out from the heated container. In some cases, a portion of the auger is disposed in a heated cover. In some cases, the cover further comprises a gate that is configured to open (and close) to allow the asphalt concrete to flow from (and be retained in) the heated container. Other implementations are also described.
