Evidence / synthetics against asphaltics

The evidence.

The case for changing, in four lines. Then the wear numbers, from an independent rig.

01Synthetics against asphaltics

The case for changing is arithmetic.

Most Australian mills still run asphaltic open-gear compounds. Four lines decide it.

Consumption

About half.

Synthetic film meters at roughly half the rate of asphaltic compound.

Clean-down

No hardening in the tooth root.

Asphaltics bake into residue that has to be dug out. Synthetics don't build up.

Compliance

TCLP-safe waste.TCLP

Used lubricant tests TCLP-safe. One less hazardous stream to manage.

Inspectability

A film you can see through.

The film runs clear. Crews monitor tooth contact in service, not at shutdown.
