Broadway, the depth of the existing asphalt surfacing was discovered to be 3 to 4 inches thick,
less than the assumed depth of 5 inches. The remaining asphalt depth of 0 to 1 inches thick
has been severely damaged by construction of the waterline.

reconstructing the road so the new section consists of 4 inches of compacted crushed surfacing
top course, surfaced with 4 inches of Hot Mix Asphalt.

pavement on the west end of the project constructed by WSDOT when the Broadway bridge
over 190 was constructed.

Date: October 3, 2008

Plan Ref: Plan Sheets 3, 4 & 5 Specification Ref: 5 -04
TOPIC: North Side Road Reconstruction
ACTION: When the bituminous surfacing was removed to the plan depth of 3 inches
on the north side of Broadway, the depth of the existing asphalt surfacing
was discovered to be 3 to 4 inches thick, less than the assumed depth of 5
inches. The remaining asphalt depth of 0 to 1 inches thick has been
severely damaged by construction of the waterline.
Instead of placing an overlay on the damaged surface it is preferable to
reconstruct the north side of the road by removing a total 5 inches of
existing material and reconstructing the road so the new section consists of
4 inches of compacted crushed surfacing top course, surfaced with 4
inches of Hot Mix Asphalt.
The area of the road reconstruction is from Centerline (21' from North
Face of Curb) from Station 97 +50 to Station 105 +84 plus street
approaches on Lily Rd, Girard Rd and Bowman Rd. The quantity has
been adjusted by removing the waterline patch area paid for under Bid
Item B13, 2" ACP Surface Restoration

CIP No.: 0068
Plan Ref: Plan Sheets 3 & 4, Trench Section Sheet B3 Specification Ref: 5 -04
TOPIC: Waterline Trench Excavation Station 91 +80 RT to 95 +60 RT
ACTION:
When the waterline was excavated in this portion of Broadway Avenue the existing
pavement depth was discovered to be approximately 7 to 8 inches thick. Two inches
have been removed by planing prior to waterline construction. The waterline trench
excavation on Sheet B3 calls for patching back with six inches of crushed surfacing top
course under a 2 inch Hot Mix Asphalt (HMA) patch below the overlay.
The City desires to match the existing pavement depth within the patch in this area. In this
area, place 6 inches of crushed surfacing top course (CSTC) on top of the trench backfill to
the bottom of existing asphalt. The CSTC shall be paid for under Schedule A, Crushed
Surfacing Top Course. Actual payment will be based on truck tickets for actual material
installed.
Place HMA to match the full depth of the existing asphalt section. The bottom 2 inches shall
be paid for under Schedule B , Item 13, 2" ACP Surface Restoration, calculated by neatline,
9 feet wide. The remaining HMA will be paid for under Schedule A, Item 11, HMA Cl. 1/2"
PG 64 -28. Actual payment will be based on truck tickets for actual material installed.
The removal of excess trench backfill shall be paid for by neatline measurement, 6 inches
deep, 9 feet wide, by 380 linear feet for 64 CY, paid at $30/ CY under Change Order 3.
