low. This could cause a premature joint failure. If

there is too much material in the joint area a bump

will be produced.

Operating Hints

The following are some specific considerations for

operation of asphalt pavers. While not all-inclusive,

following these recommendations should reduce

the risk of problems and improve rubber track dura-

bility and reliability.

Asphalt Buildup

Figure 7.19

- Asphalt Buildup

During paving, asphalt sometimes flows down to

the rear drive wheel and can become packed be-

tween the tractor and screed. This may cause the

following problems:

•

Oil in the asphalt will cause the rubber to

soften and reduce the durability.

•

Aggregate will abrade the rubber and

shorten its life.

•

Asphalt material buildup in the undercar-

riage will cause additional tension.

Hydraulic Tunnel

Figure 7.20

- Hydraulic Tunnel Extended

To help prevent asphalt from flowing down to the

rear wheel, two options are available: manual ma-

terial retaining plates and hydraulic tunnel. The ma-

chine is equipped with manual retaining plates by

default unless hydraulic tunnel option is elected.
Hydraulic tunnel can be extended or retracted by

operating a switch located in the screed console.

Extend tunnel before paving begins. Tunnels auto-

matically retract with screed retraction.
