SC -07 -002 <br />1 <br />REVISION OF SECTION 403 <br />HOT MIX ASPHALT <br />Section 403 of the Standard Specifications is hereby revised for this project as follows: <br />Subsection 403.02 shall include the following: <br />The design mix for hot mix asphalt shall conform to the following: <br />Table 403 -1 <br />January 4, 2013 <br />All mix designs shall be run with a gyratory compaction angle of 1.25 degrees and properties must satisfy Table <br />403 -1. Form 43 will establish construction targets for Asphalt Cement and all mix properties at Air Voids up to <br />1.0 percent below the mix design optimum. <br />10 <br />
