(1) This is a minimum requirement. The average during construction

shall be significantly higher than this number to ensure compliance

with the specifications.

(2) The flow requirement is not applicable for Polymer Modified

Asphalts

(3) Dust Proportion is calculated as the aggregate content, expressed

as a percent of mass, passing the 0.075 mm No. 200 sieve, divided by

the effective asphalt content, in percent of total mass of the mixture.
