Machine, system and method for resurfacing existing roads using premixed stress absorbing membrane interlayer (SAMI) material
Various implementations include a machine for resurface existing roads. The machine may include a premixed stress absorbing membrane interlayer (SAMI) material distribution component configured to distribute a premixed SAMI material on an existing road. The distributed premixed SAMI material may include a mixture and/or combination of binding material and pre-cut fiber material. The machine may also include a channel positioned adjacent and downstream of the premixed SAMI material distribution component. The channel may be configured to supply an asphalt mixture directly over the premixed SAMI material. Additionally, the machine may include a screed positioned adjacent the channel. The screed may be positioned to contact the asphalt mixture.

4. A method of resurfacing an exposed surface of an existing road, the method comprising:
a) positioning a machine on the existing road, the machine comprising:
a premixed stress absorbing membrane interlayer (SAMI) material distribution component configured to distribute a premixed SAMI material on an existing road, the premixed SAMI material including a binding material and a pre-cut fiber material;
a channel positioned adjacent and downstream of the premixed SAMI material distribution component, the channel configured to supply an asphalt mixture directly over the premixed SAMI material;
a screed positioned adjacent the channel, the screed positioned to contact the asphalt mixture, wherein the channel is positioned between the premixed SAMI material distribution component and the screed;
a material storage in communication with the premixed SAMI material distribution component, the material storage storing the premixed SAMI material;
a plurality of supply lines in communication with and coupling the material storage and the premixed SAMI material distribution component, wherein the premixed SAMI material includes a combination, amalgamation, and/or mixture of the binding material and the pre-cut fiber material, wherein the pre-cut fiber material comprises strands of fiber material;
