Asphalt Production Essentials


(The Safe and Efficient Operation of Asphalt Plants)

Asphalt hot mix is a more important part of the New Zealand construction industry. As plants become more automated and controlled the emphasis on operation is firmly on safety and quality. Different plants have different operation and control procedures but this course concentrates on the practicality of using the tools to make quality mix for clients that can be laid to a durable pavement surfacing or full depth asphalt construction.

Thorough product and plant knowledge, coupled with skilled maintenance and operational procedures is needed for the economical production of asphalt mixes from both fixed and mobile plants.
