Abstract: The present invention provides an improved heated hose for use with asphalt pavement repair machines that includes a flexible exterior cylindrical insulated hose portion with an inner cylindrical surface defining an inner cylindrical region, and a flexible metal sheath deployed coaxially in this region having an exterior surface, the surfaces defining an area through which hot asphalt flows. A heating element may be removably deployed inside and along the length of the coaxial metal sheath. Hot asphalt flowing through the hose between the inner cylindrical surface of the hose and the exterior surface of the coaxial metal sheath is kept hot by the conduction of heat from the heating element inside the flexible metal sheath. One end of the heating element extends to a far end of the inside of the sheath, and the other end of the heating element is accessible from outside of the near end of the hose, making it possible to easily remove and replace the heating element in the event of a failure.
