aggregate was selected to be the amount retained above the No. 8 sieve. The aggregate retained above the No. 8 sieve represents approximately 60% of the total aggregate weight and would be approximately 50% of the exposed aggregate surface. For Mix 1, 50% of the aggregate blend was crushed gravel retained above the No. 8 sieve.

Aggregate for plant mix base and leveling courses shall consist of coarse aggregate, fine aggregate, and mineral filler when required. Prior to the approval of the jobmix formula and at .

It is important that a Job Mix Formula (JMF) for the paving mixture be established. A producer, providing standard mixes, can readily furnish the engineer with a written JMF.
