Plan Sheet changes

Questions / Clarifications

The following questions and issues were submitted via email at eflhd.contracts@dot.gov. The Government response or clarification is provided. Due to the repetitive nature of several questions and issues, the wording of the questions may have been revised and some questions have not been included. The Government’s direct response to the sender may also have been updated below for better clarity.

1. Can the existing pavement be ground with a reclaimer?

Response: Yes, a reclaimer may be used for grounding the existing pavement. Milling was specified as opposed to reclamation, because of the presence of boulders in the area, some which cannot be seen. Boulders could damage the reclaimer.

2. Aggregate base grading is listed as 1300 tons. How do we weight what we are grading, or we importing in the 1300 tons?

Response: Pay Item 30101-4000, AGGREGATE BASE GRADING C OR D, is for furnishing and placing aggregate material according to Section 301. The 1300 tons of aggregate base course is the amount of additional material that we calculated that is needed for the leveling course between the milled surface and the Suparpave pavement layer. This quantity also includes the material to be used to build the shoulders of the roadway.” The aggregate base will be measured by the ton according to Subsections 109.02(o) and 109.03.
