The responses to bidder's inquiries, unless incorporated into a formal addendem to the contract, are not a part of the contract and are provided for the bidder's convenience only. In some instances, the question and answer may represent a summary of the matters discussed rather than a word-for-word recitation. The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements. 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.
