Abstract: A bulk material hauling tractor and trailer unit comprises a truck tractor having a bottom dump hopper mounted on its chassis. The tractor tows a double axle pup trailer by an elongated tongue having a span of at least twice the trailer wheelbase. The trailer has nonsteerable axle assemblies and supports a bottom dump material transport hopper. The tractor and trailer hoppers are fabricated of conventional steel plate and structural sections and are formed with a reentrant top wall portion to provide a reduced top opening and increased hopper rigidity. The hoppers present relatively low frontal area and aerodynamic drag characteristics and low center for gravity for exceptional stability for over-the-highway as well as off road hauling.

Abstract: A method and apparatus for recovering viscous fluid such as asphalt, which utilizes an elongated insulated buoyant housing with an elongated heating element disposed therein. The heating element extends through the elongated housing and out at an open end thereof to heat the viscous fluid. A pump located at a second end of the elongated housing is utilized to draw the heated viscous fluid through the housing. The insulated nature of the housing concentrates the output of the heating element into the fluid within the housing and prevents heat loss.
