Bidders are cautioned that subsequent responses or contract addenda may affect or vary a response previously given.

Q1) The type of binder for both HMA and RHMA (Gap Graded) are different than what is usually required. Is it the State's intention to use PG 64-28 instead of PG 64-10 for the HMA and PG 58-22 instead of PG 64-16 for the RHMA?

A1) Submitted for consideration. 30Apr10

Q2) Please change the binder for the RHMA-G from PG 58-22 to PG 64-16. The Division of Design sent out a directive, dated June 27, 2008, listing the proper liquid asphalts to be used in the different geographic areas of California. Table 632.1 of the Highway Design Manuel clearly states PG 64-16 should be used in the inland valleys. Also, they listed PG 64-28 for the HMA and it should have been PG 64-10.
