JMF(s)’” they can be used to create a Job Mix Formula Note: (Asphalt Mix Designs in ‘Pending’, ‘Rejected’, or ‘Not In Use’ status cannot directly be used to create a Job Mix Formula The Asphalt Mix Design would first have to be approved before it could be used to create a JMF) To Create a Job Mix Formula from an approved AMD:.

Reviewing asphalt test results

The purpose of requiring a gradation on field samples is to help ensure that the asphalt plant used the same aggregates as reported on the asphalt mix design, in the same proportions The gradation of all of the aggregates mixed together, plus the design binder content is called the job mix formula (JMF).

Job Mix Formula

The end result of a successful mix design is a recommended mixture of aggregate and asphalt binderThis recommended mixture, which also includes aggregate gradation and asphalt binder type is often referred to as the job mix formula (JMF) or recipe For HMA manufacturing, target values of gradation and asphalt binder content are specified based on the JMF along with allowable.

Theoretical Maximum Specific Gravity

Overview The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity Theoretical maximum specific gravity can be multiplied by the density of.
