*** Question and Answer #9 ***
Question #9. Page 59 of 63 of the Solicitation, the definition of "Full Replacement (FR) means those processes in which all of the asphalt pavement layers and some portion of the underlying bound or unbound layers are pulverized, stabilized, and compacted in place. Install base course approximately six inches and asphalt approximately two to three inches thick."
(a) Please confirm that the term “stabilized” as shown in the definition shown above is to be done as described SECTION 32 11 23, ARTICLE 3.4 Preparation of Underlying Course or Subgrade. If not, please advise which section of the specification would apply.
(b) The base course which is to be installed at approximately six inches prior to the asphalt at two to three inches. Please confirm that this course is an “aggregate” base course in accordance with SECTION 32 11 23. If not, please advise which section of the specification would apply.
Answer #9(a). Section 32 11 23 Aggregate Base Course for Flexible Paving, Article 1.2 Definitions, as well as Subparagraphs 2.1.1.1 and 2.1.2.1 Aggregate Base Course, and Article 3.4 Preparation of Underlying Course or Subgrade, among others, discuss “aggregate base course” including mechanical stabilization by compaction and degree of compaction required.
The definition of Full Replacement (FR) on page 59 of 63 of the Solicitation indicates "...and some portion of the underlying...layers...." Therefore, Contractor should not assume all underlying material gets replaced. Contractor shall inspect the underlying layers for consistency and conduct testing as specified in Section 32 11 23 such that Contractor meets specified compaction and surface tolerances. Tolerances are indicated--in conjunction with whole of the Specification--in Section 31 11 23 Article 1.6 Acceptance.
Answer #9(b). The “base course” discussed in Section 01 00 00 General Requirements, and Section 32 11 23 Article 3.5 Grade Control, is indeed the aggregate base course specified in Section 32 11 23. Install aggregate base course as specified to meet the necessary grade.
