443.01 Description. This work consists of constructing a stone matrix asphalt
concrete (SMA) course consisting of aggregate, asphalt binder, and additives.
The requirements of 442 and 446 apply except as follows. Do not use the warm
mix asphalt method (402.09) for this item.
443.02 Quality Control Program. Update the Quality Control Program
meeting 403.03 to include a section for how the quality control, production and
placement of SMA will meet this specification. Submit the revised program to the
Laboratory with the SMA mix design to be approved.
443.03 Composition. Discuss the mix design approach with the Laboratory
during the mix design and prior to submittal.
A. Design Limits. Submit a JMF to the Laboratory which meets the
requirements of Table 443.03.1 and Table 443.03-2.
