As depicted, there are three pairs of intermediate rollers (70a, 70b and 7c), where each of the intermediate rollers 70 has a smaller diameter than the leading rollers 60. As shown in the figures, the intermediate rollers 70 are disposed at the base of the body 30. [0036] Leading 60 and trailing 62 rollers may comprise multiple layers including a solid metal core 64 surrounded by one or more outer layers 66 made of different material than the core. In one embodiment, the core of the leading and trailing rollers is steel and the outer layer is a resilient material.

- the drive wheels 80 are rotated using rotational force generated by one or more hydraulic motors which may be powered by a main engine 22 of the compactor.
- Leading 60, trailing 62, and intermediate rollers 70 define a planar bottom run of the belt 52, whereby the bottom run 52 of the belt 50 defines the compaction surface of the apparatus 10.
- the leading 60, trailing 62, and intermediate rollers 70 exert a substantially downward pressure on the bottom run 52 of the belt 50 to provide a uniform pressure applying surface over the area of the belt 50 in contact with the surfacing material 2.
- the apparatus 10 creates a larger footprint allowing the compaction process to take place over a longer period of time to compress any air out of the compacted surfacing material and provide for better quality compaction of asphalt, for example.
- the belt 50 is wound around the leading 60, trailing 62, and intermediate rollers 70, and the drive wheel 80.
- Each one of the pair of the leading rollers 60, trailing rollers 62, and intermediate rollers 70 are separated from the other pair by a gap 82.
- Gap 82 is dimensioned to receive belt retaining members 56 to secure the belt 50 to the apparatus 10 when the belt 50 is wound around the body 30.
- the belt 50 may resist lateral slippage during use where use may include operation on unlevel surfaces such as superelevation.
- the belt 50 will turn and will act as an endless track for the leading 60, trailing 62, and intermediate rollers 70 and the compactor 12 will move in a direction desired by the operator.
- the compactor 12 may also be equipped with a number of accessories that are advantageous for the compaction process.
- the belt 50 may be heat resistant and in some aspects, may be subjected to at least the temperature suitable for compacting freshly laid asphalt, for example about 120°C to about 150°C or more before or during the compaction process. In some aspects, the heating of the belt 50 may also ensure that the bitumen on the surface of the asphalt substantially does not adhere to the belt 50.
- the belt 50 may be heated by any suitable means, for example a super-heated air generator or direct flame heating such as propane flame heating.
- a thermal insulating shroud 90 which overlies the belted compaction apparatus 10 or the compaction assemblies 16, 20 may also be provided.
- Shroud 90 alleviates heat loss from those portions of the belt 50 not in contact with the surface of the asphalt.
- the shroud 90 may be formed in part or wholly by an insulating shroud and advantageously extends over the belt 50 at least substantially to the level of the compaction surface.
- Shroud 90 may be formed in one or more parts, for example from reinforced plastics such as fiberglass or a metal such as aluminum or steel with or without insulation.
- a scraper bar may be provided to remove excess asphalt fines accumulated on the belt during the surfacing material compaction process.
- An asphalt fines collection means may also be provided to collect the excess asphalt fines so that the excess asphalt fines are kept away from the compacted surface.
- a belt degreasing means and a degreaser reservoir may be provided for degreasing the belt 50 during the surfacing material compaction process.

- a free end of the piston 96 is secured to the body 30 and actuation of the piston 96 will permit sliding movement of the axle housing 94, and therefore the leading wheels 60, in relation to the body 30.
- the tension on the belt 50 being adjustable by the movement of the piston 96 because the belt 50 is wound around the leading 60, trailing 62, and intermediate rollers 70, and the drive wheel 80.
- the pressures exerted on the belt 50 are about 2000 lbs.
- the compactor 12 and apparatus 10 may be configured to suit many different types of applications and environments wherein the
- apparatus 10 may be configured to have the depicted dimensions which result in an overall weight of 8.90 t or 19621.14 lbs; a surface area of 3797.25 in 2 ; to exert a ground pressure of 5.17 psi or 35.6 kPa.
