SALMON CREEK RECONSTRUCTION NOTES: ASPHALT NOTES

General Notes:

1. These notes are to be used in conjunction with all Specifications and the Drawings. The Specifications take precedence over these notes.

2. All new asphalt shall conform to the widths of the existing asphalt surface.

3. Asphalt patch all potholes that are over 2” in depth in the sections where existing asphalt is to be used as base.

4. Clean and Tack-coat all sections where new asphalt is placed on existing asphalt with SS1H Tack Coat or equivalent.

5. Sections recently paved in good condition: Use a 1.5” overlay on recent sections in good condition with no cracks as designated by the Engineer.

6. Sections where existing asphalt can be used as sub-base: Use 3”overlay over old roadbed where the old asphalt is good enough to use as the sub-base needing only to fill the potholes prior to paving.

7. Sections to be totally reconditioned: Use 3” overlay on top of totally reconditioned sub-base sections. Rip up existing roadbed. Pulverized asphalt may be used with ¾” crushed aggregate as compacted base material. Reconstructed sections shall be out- sloped at 2% to the west (creek side) of the road. Sections shall be approved in writing by the engineer prior to paving.

8. All prep work such as grinding and relaying, pothole patching etc. shall be completed and approved by the engineer in writing before new paving starts.

Asphalt Notes:

Main Campground Road (DRAWINGS: Paving, Culvert and Ditch Reconstruction Sections 2-4)

2+70 End 1.5” overlay. Begin 2” overlay using existing asphalt as base -average width 19’

3+50 Continue 2” overlay using existing asphalt as base, width 32’ in the middle of the intersection.

3+70 End 2”overlay. Begin 3” overlay using existing asphalt as base; fill potholes prior to paving.

4+00 End intersection. Continue 3” overlay using existing asphalt as base - average width 26’

5+00 Continue 3” overlay using existing asphalt as base - average width 19’

5+75 End 3” overlay. Begin 1.5” overlay using existing asphalt as base - average width 20’

6+90 End 1.5” overlay. Begin reconstruction. Reconstruct base, rip up old asphalt and aggregate. Old asphalt may be pulverized and used with ¾” crushed aggregate to become 4” of compacted base. Engineer shall approve base prior to paving. Place 3” new asphalt on reconstructed section. The new reconstructed area will be out-sloped at 2% to the west (creek side) of the road. Average width 18’.

8+85 End complete reconstruction. Begin 1.5” overlay using existing asphalt as base -average width 18’.

9+70 End 1.5” overlay. Begin reconstruction. Reconstruct base, rip up old asphalt and aggregate. Old asphalt may be pulverized and used with ¾” crushed aggregate to become 4” of compacted base. Place 3” new asphalt on reconstructed section. The new reconstructed area will be out-sloped at 2% to the west (creek side) of the road. Average width 18’.

15+20 End complete reconstruction. Begin 1.5” overlay using existing asphalt as base -average width 18’.

15+85 End 1.5” overlay. Begin 3” overlay using existing asphalt as base; fill potholes prior to paving. Average width 18’.

22+30 Intersection with end loop. Continue 3” overlay using existing asphalt as base. Average width 18’. Conform new asphalt width to existing asphalt on the ground. Conform to existing asphalt at the end of the loop.

22+50 Continue 3” overlay using existing asphalt as base.

23+00 Continue 3” overlay using existing asphalt as base. Average width 11’.

24+85 Continue 3” overlay using existing asphalt as base. Begin turnout. Width 42’ at widest part of turnout.

26+50 Continue 3” overlay using existing asphalt as base. Average width 12’.

28+50 Intersection with end loop. Continue 3” overlay using existing asphalt as base. Average width 24’.

28+66 End of Stationing at centerline. End paving once the intersection is reached and the end loop is complete.

OPTION: First Loop Overlay (DRAWINGS: OPTION: Paving, Culvert and Ditch Reconstruction Section 1)

0+00 Intersection Loop 1 (See Loop 1 notes below. STA 1+75 = STA 0+00 of Loop 1) No work required.

0+70 Begin 3” overlay using existing asphalt as base; fill potholes. Average width 10’.

12+50 End 3” overlay at intersection of Loop 1 with main road.

SALMON CREEK RECONSTRUCTION NOTES: DITCH AND WATERLINE RECONSTRUCTION NOTES

1. Ditch reconstruction is on the east side of the roadway and work to be completed is designated by the centerline stationing. Roadside ditch reconstruction shall be in conjunction with culvert installation.

2. These notes are to be used in conjunction with all Specifications and the Drawings. The Specifications take precedence over these notes.

Ditch and Waterline Reconstruction Notes:

Main Campground Road

Loop 1 Road Drainage is functioning. No work required.

SALMON CREEK RECONSTRUCTION NOTES: PIPE LOCATION AND SIZE RECONSTRUCTION NOTES

1. These notes are to be used in conjunction with all Specifications and the Drawings. Please refer to these items for proper installation. The Specifications take precedence over these notes.

2. All pipes shall be set at a minimum of 2%.
