| 11-1036 | 301 | Hardin | Concerning item 0180/0670/0430 Cement Concrete Entrance 8”, the plan sheets only specifically indicate about 330 SY of concrete entrances vs the bid quantity of 1456 SY. However, the paving summary indicates 609 sy entrances and 847 sy of Frontage Road 4. Please clarify. |
Beginning with plan sheet R17, the Concrete Entrance Construct notes are called out by note versus inclusion in a table.

| 11-2974 | 306 | Hopkins | Is there a description/note for what material should be used, depth, etc. for Approach Pavement? |
Materials
Class 2 Asphalt Surface 0.38 PG64-22. This material shall be in accordance with the Standard Specifications.
Tack Coat. This material shall be in accordance with the Standard Specifications
Construction
A. Remove Existing Materials. Remove the existing pavement material to provide for a minimum of 1¼” new pavement surface from the bridge end extending approximately 100 feet into the approach pavement and across the width of the approach pavement. The Engineer shall determine the actual length and width of the milling depending on site conditions at each bridge approach. Mill the existing surface so that the new asphalt surface will tie into the new armored edge and matches the original cross section of the approach. Mill a 3-foot edge key to tie the new surface into the existing surface approximately 100 feet from the bridge end. The Engineer shall approve the Contractor’s plan for restoring the approach grade prior to the removal of the existing surface. Dispose of all removed material entirely away from the job site or as directed by the Engineer.
Backfill the area of pavement removed for placing the new armored edges with concrete of the same mix design as the overlay (minus the latex) to within 2” +/- of the top of the bridge end. Allow this concrete to wet cure prior to placing the new asphalt surface on it.
B. Produce and Place New Asphalt Surface. Apply an asphalt tack coat in accordance with Section 406. Produce and place the new 1 ¼” asphalt surface in accordance with Section 403 and compact under Option B. The new asphalt surface mixture required for this project shall be “Class 2 Asphalt Surface 0.38D PG 64-22”. Place the new asphalt surface to the original roadway cross section or as directed by the Engineer.
C. Treatment of Shoulders. On roadways with paved shoulders, the shoulders shall receive identical treatment to the mainline pavement. On roadways with earth or rock shoulders, the Contractor shall attempt to protect the shoulder from damage. Any damage to earth or rock shoulders shall be repaired by the Contractor to the satisfaction of the Department at no additional cost. These repairs may consist of re-grading, re-compacting, and/or placing millings to return the shoulder to its original cross section.
Measurement
Will be in Square Yards
Payment
Payment at the contract unit price per square yard is full compensation for backfilling at the end of the structure, removing existing pavement markers, mobilization of milling equipment, removing specified existing pavement material, furnishing and installing the asphalt tack coat, producing and placing the new asphalt surface, shoulder treatment, and all incidental items necessary to complete the work within the specified pay limits as specified by this note.
The Department will consider payment as full compensation for all work required by these notes and detail drawings.
