Speaker: Jon M. Young, PE, Hawaii Asphalt Pavement Industry
Who Should Attend: Contractors, engineers, and construction managers unfamiliar with a JMF submittal.
The job mix formula (JMF) is the recommended mixture, which includes aggregate gradation and asphalt binder type, to meet the project specifications. The JMF submittal is prepared by the paving contractor for any project that requires the construction of an asphalt pavement. The submittal is typically reviewed by the engineer of record.
This 90-minute, plus questions and answers, workshop will discuss 1) the basics of asphalt pavement mixes, by discussion the Marshall method, which is the most widely used in Hawaii, 2) the production of asphalt pavements, and 3) how the JMF submittal relates to the project specification, using the Department of Transportation, 2005 Standard Specifications as an example.
Takeaways:
– A basic understanding of asphalt pavement mixes
– A basic understanding of how asphalt pavements are produced
– An understanding of how to review the JMF submittal for conformance to a specification
