| 1. A system for recycling pavement constituents in situ, comprising:
a vehicle for traversing the pavement constituents;
the vehicle comprising a container for storing heated pavement rejuvenation materials;
the vehicle further comprising at least one heating element adapted to heat and preserve the pavement rejuvenation materials
above their working temperature;
a dispensing element in communication with the container for dispensing the pavement rejuvenation materials into the pavement
constituents;
and a plurality of mixing elements supported by the vehicle;
the mixing elements being adapted to mix in situ the pavement constituents and the heated pavement rejuvenation materials
together in such a manner that the pavement constituents are raised to a working temperature, and
a compacting element for compacting the resulting mixture of pavement constituents and pavement rejuvenation materials into
a new road surface;
wherein at least one of the plurality of mixing elements rotate around an axis substantially normal to a road bed and wherein
at least one of the plurality of mixing elements is adapted to move independent of another mixing element of the plurality
of mixing elements to avoid obstacles on the road bed.
