CONSTRUCTION OF PLANT-MIXED ASPHALT FINE-GRADED COURSES

410.1DESCRIPTION—This work is the standard and RPS construction of a plant -mixed asphalt wearing

course on a prepared surface using a volumetric mixture design developed with the Superpave Gyratory Compactor and modified to be a fine-graded (FG) mixture.

410.2MATERIALS—Section 413.2 using the procedure and volumetric tolerances for the 9.5 mm nominal

maximum aggregate size mixture and modified as follows:

nominal maximum aggregate size mixture, except the JMF must have a minimum percent passing the No. 8 sieve of 47% and a maximum percent passing the No. 8 sieve of 67%.

410.3CONSTRUCTION —Section 413.3 using the test procedures, limits , and tolerances for a 9.5 mm

nominal maximum aggregate size mixture except where procedures, limits and tolerances are specifically indicated for a 9.5 mm fine-graded nominal maximum aggregate size mixture and as modified as follows:

Revise Table G to include 9.5 mm Fine Grade Wearing Course as follows:

TABLE G Mixture Minimum Compacted Depths Mixture Minimum Depth 9.5 mm Fine Grade Wearing Course 1 inch

410.4MEASUREMENT AND PAYMENT—Square Yard or Ton

Paid as specified in Section 413.4 for a 9.5 mm Wearing Course.
