Evidence / synthetics against asphaltics
The case for changing, in four lines. Then the wear numbers, from an independent rig.
01Synthetics against asphaltics
Most Australian mills still run asphaltic open-gear compounds. Four lines decide it.
Consumption
Synthetic film meters at roughly half the rate of asphaltic compound.
Clean-down
Asphaltics bake into residue that has to be dug out. Synthetics don't build up.
Compliance
Used lubricant tests TCLP-safe. One less hazardous stream to manage.
Inspectability
The film runs clear. Crews monitor tooth contact in service, not at shutdown.
