Subclause 8 (see link below) of the regulations specifies:
The standard means that the burning of bitumen on a road is banned. Consents are unable to be granted for this activity in any form. This overrides any “exemptions” that may have been agreed between road controlling authorities and local government. This standard applies from 8 October 2004.
Road controlling agencies are moving away from bitumen burning to other options, such as high-pressure water blasting. During water blasting the debris and wastewater should be collected and disposed of.
