When material is used from a stockpile that has not been tested as <br />provided above, the reGuirements for fracture and sand equivalents shall apply at the <br />time of its introduction to the cold feed of the mixing plant. <br />The properties of the aggregate in a preliminary mix design ior HIv1A shall be such <br />that, when it is combined within the limits set forth in Proport�ons of Materials and <br />mixed in the laboratory with the designa;.;d grade of asphalt binder, HMA mixtures <br />with the following test values can be produced: <br />Stabilome�er Value Min. <br />Cohesiometer Value Min. <br />Percent Air Voids <br />Modified Lottman <br />Slripping Test <br />Class of HMA <br />A B D E <br />37 35 --- 35 <br />100 100 — 100 <br />2-4.5 2-0.5 --- 2-4.5 <br />Pass Pass Pass Pass <br />F G <br />35 35 <br />50 100 <br />2-4.5 2-4.5 <br />Pass Pass <br />' C.
