Dear Construction Manual Update Subscribers,

We have posted Construction Policy Bulletin 15-6, "Implementation of Hot Mix Asphalt Superpave Mix Design," on our website:

http://www.dot.ca.gov/hq/construc/manual2001/CPBindex.HTM

Revised Section 39, "Hot Mix Asphalt," in the 2010 revised Standard Specifications includes Superpave mix design methodology which replaces most Caltrans test methods with American Association of State Highway and Transportation Officials (AASHTO) test methods. The bulletin provides guidance on requirements of the contractor's mix design, new requirements of sample sizes, and announces updates to Forms CEM-3511, CEM-3512, CEM-3513, CEM-3514, and CEM-3703. Revised sampling and testing frequencies are shown in the attached Construction Manual, Table 6-1.12, "Materials Acceptance Sampling and Testing Requirements: Hot Mix Asphalt."
