**Section 702. - ASPHALT MATERIAL**

**702.01 Asphalt Binder.** [Delete the Subsection and add the
following:]{.underline}

**702.01 Asphalt Binder.** Conform to M 320, Table 1. Conform to
Subsection 702.04.

In AASHTO M 320, Table 1 replace footnote *g* with the following:

*^g^* If the creep stiffness is below 300MPa, the direct tension test is
not required. If the creep stiffness is between 301 and 600 MPa, the
direct tension failure strain requirement shall be used in lieu of the
creep stiffness requirement. The *m*-value requirement must be satisfied
in both cases.

  -----------------------------------------------------------------------
  When an Open Graded Friction Course is specified, use the following:

  -----------------------------------------------------------------------

**702.01 Asphalt Cement.** [Add the following:]{.underline}

Asphalt cement for the open-graded asphalt friction course will be
viscosity Grade AC-20 (P or R) conforming to Table 702-2 and Subsection
702.04. Add the rubber additive at the refinery.
