Claim:
A hot-in-place recycling and repaving machine for recycling and repaving an existing asphalt-based pavement, comprising: at least one preheater unit for heating a surface of the pavement; a first set of scarifying rakes for scarifying the heated surface of the pavement in a first scarification process; an aggregate bin for dispensing new aggregate onto the heated and scarified asphalt surface to form a recycled, preheated asphalt and aggregate mixture; and a recycling machine comprising: a. one or more heaters for heating the recycled preheated asphalt and aggregate mixture to within a predetermined temperature range; b. a second set of scarifying rakes for scarifying the recycled heated asphalt in a second scarification process which premixes the recycled asphalt and aggregate mixture and forms a new recycled asphalt and aggregate mixture; c. a plurality of extension mills for milling the pavement surface to grade and width by applying a mixing application of the new recycled asphalt and aggregate mixture; d. a main mill for remilling the pavement surface to grade by applying a mixing application of the new recycled asphalt and aggregate mixture; e. a first rejuvenator fluid containing first liquid additives introduced to the to the new recycled asphalt and aggregate mixture of the main mill from a rejuvenator supply associated with the main mill and comprising part of the rejuvenator application system, the rejuvenator application system including rejuvenator spray bars; f. a pug mill receiving the new recycled asphalt and aggregate mixture of the main mill; g. a second rejuvenator fluid containing second liquid additives introduced to the new recycled asphalt and aggregate mixture of the pug mill using the rejuvenator application system, the pug mill having first and second downwardly rotating rotors for mixing, wherein a substantially homogenous mixture of rejuvenator-enriched, recycled asphalt and aggregate windrow is formed; and h. at least one screed for laying the homogeneously mixed windrow to grade.
