Applicator and method for applying melted rubber to pavement comprises a melting vat having a substantially planar bottom with a surface area, and a wide-area a heating element beneath the melting vat having a surface area more than half the surface area of the planar bottom of the melting vat and positioned beneath the melting vat. The heating element may be comprised of an aluminum oxide ceramic blanket. A double-walled construction of the vat with exhaust holes in the outer wall allows exhaust to evenly melt rubber in the vat to reduce burning of the rubber, flame blowouts, and improve fuel efficiency.

An asphalt aggregate paver (1) for asphalting a surface (116) to be asphalted includes an asphalt aggregate receiving hopper (2), width-wise spreading means (4) for distributing the aggregate over the surface (116), and conveyor means (6) arranged between the receiving hopper (2) and the spreading means (4) for feeding said spreading means (4), by conveying said aggregate from the hopper to said spreading means (4) in a longitudinal direction (L). The paver further includes mixing means (8), which are a separate element of said conveyor means (6). The mixing means (8) are arranged between said receiving hopper (2) and said spreading means (4), and the mixing means (8) are movable with respect to the conveyor means (6) for stirring the aggregate when it is conveyed. The mixing means (8) are arranged outside and after the receiving hopper (2).

Mobile mixing devices, mobile mixing systems, and related methods are provided. A mobile mixing device can include a frame and a mixing drum securable to the frame. The mixing drum can include a body that forms an internal cavity and can have a forward end and a bottom end. The mixing drum can also include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing device can include a heater support arm having a heater secured to an end of the heater support arm that is distal from the mixing drum. The mixing drum can be used to process cement material when the heater support arm is in a stow-away position or asphalt when the heater support arm is in a heating position with the heater facing into the mouth of the mixing drum.
