Paving machine membrane dispenser

1. An asphalt paving system for dispensing hot asphalt material to form a paved surface, the asphalt paving system comprising:

an asphalt paving machine comprising a hopper and first and second supports, where

the asphalt paving machine defines a front, first and second sides lateral to the first and second supports, and a center area between the first and second sides, and

the hopper is configured to store the hot asphalt material;

a plurality of dispensing shafts mounted on the asphalt paving machine, where

at least a portion of at least one of the plurality of dispensing shafts extends beyond the first side of the paving machine,

at least a portion of at least one of the plurality of dispensing shafts extends beyond the second side of the paving machine, and

at least a portion of at least one of the plurality of dispensing shafts extend from the front of the paving machine and is arranged entirely within the center area of the paving machine; and

a plurality of rolls of pavement reinforcing membrane, where

the pavement reinforcing membrane is asphalt bitumen coated, and

each of the plurality of dispensing shafts supports one of the plurality of rolls of pavement reinforcing membrane; whereby

as the asphalt paving machine moves,

the plurality of dispensing shafts dispense the pavement reinforcing membrane continuously beneath the asphalt paving machine, and

the hot asphalt material is dispensed from the hopper on top of the pavement reinforcing membrane beneath the asphalt paving machine.

2. An asphalt paving system as recited in claim 1 , in which:

each of the plurality of dispensing shafts dispenses the pavement reinforcing membrane in a membrane strip; and

the dispensing shafts are arranged such that at least a portion of each of the membrane strips overlaps at least a portion of at least one other membrane strip.

3. An asphalt paving system as recited in claim 1 , further comprising a screed.

4. An asphalt paving system as recited in claim 1 , wherein each of the plurality of dispensing shafts is mounted on a leading portion of the asphalt paving machine.

5. An asphalt paving system as recited in claim 1 , wherein at least three membrane strips are arranged within the center area of the asphalt paving machine.

6. An asphalt paving system as recited in claim 1 , in which the first and second supports are formed by first and second support tracks, respectively.

7. An asphalt paving system as recited in claim 1 , in which

each of the plurality of dispensing shafts dispenses the pavement reinforcing membrane in a membrane strip;

at least a portion of at least one of the membrane strips is arranged laterally outside of first support, and

at least a portion of at least one of the membrane strips is arranged laterally outside of second support.

8. An asphalt paving machine system as recited in claim 7 , in which

at least a portion of each of the membrane strips overlaps at least a portion of at least one other membrane strip.

9. An asphalt paving system as system in claim 1 , wherein the dispensing shafts are positioned to dispense pavement reinforcing membrane from the plurality of rolls of pavement reinforcing membrane in a plurality of membrane strips, where at least one of the plurality of membrane strips is arranged within the center area, at least one of the plurality of membrane strips is arranged at least partly beneath each of the first and second supports, and at least a portion of at least one membrane strip is arranged laterally outside of the first and second supports.

10. An asphalt paving system as recited in claim 9 , in which at least one side edge of each membrane strip overlaps at least one side edge of at least one adjacent membrane strip.

11. An asphalt paving system as recited in claim 9 , in which at least one side edge of ach at least one membrane strip of does not overlap a side edge of an adjacent membrane strip.

12. An asphalt paving system as recited in claim 1 , in which the pavement reinforcing membrane comprises a non-woven polymer fiber reinforcement sheet both surfaces of which are hot-coated and sand surfaced with an elastomeric modified asphalt bitumen coating forming a heat-activated bonding surface.

13. An asphalt paving system as recited in claim 12 , in which the elastomeric modified asphalt bitumen coating contains a polymer modifier.

14. An asphalt paving system as recited in claim 13 , in which the polymer modifier is elastomeric.

15. An asphalt paving system as recited in claim 13 , in which the polymer modifier is a Styrene Isoprene Styrene polymer.

16. An asphalt paving system as recited in claim 15 , in which the Styrene Isoprene Styrene polymer modifier is combined with a Styrene Butadiene Styrene polymer modifier.

17. An asphalt paving system as recited in claim 12 , in which the elastomeric asphalt coating contains from 0% to 25% of a polymer modifier.

18. An asphalt paving system of claim 12 , in which the non-woven polymer reinforcement sheet is made of polyester fibers.

19. An asphalt paving system as recited in claim 18 , in which the non-woven polymer reinforcement sheet further comprises a combination of other suitable polymer fibers.

20. An asphalt paving system as recited in claim 19 , in which the asphalt bitumen blended with the polymer modifier to coat the membrane is 80/100 penetration grade.

21. An asphalt paving system as recited in claim 20 , in which the asphalt bitumen further comprises tackifying agents.
