This is an essential risk awareness course targeted at managers, engineers and supervisors involved in managing businesses or operations that include the storage, production and transport of bituminous materials; and road surfacing works. A separate course "Bitumen - Basic Safety" is intended for all others involved in the road surfacing industry.
Bitumen is the primary sealing material used in New Zealand roads which comes in various grades and may be modified with polymers or other materials. Before 2016 bitumen was graded according to empirical consistency measures with no reference to traffic, shear or climate. Modified Binders too have been classified by empirical tests.
Precise and competent operation of the bitumen sprayer is essential to successful chipsealing operations. Sprayer performance is improved if operators have detailed knowledge of the principles of the chipsealing process and the appropriate knowledge to accurately use the equipment.
