RECENT ADAB PROJECTSWV 10 – 3.7 miles

4-lane arterial on new alignment – pre-graded 10” PCCP vs. 12.25” Asphalt Bid by the SY of Mainline Pavement 4 of the 6 bidders bid concrete and the low concrete bid was

17% lower than asphalt Low SY price was $60.00

King Coal US52 – 9.5 miles Pre-graded and bid by the SY of Mainline Pavement 10” PCCP vs. 11.5” Asphalt 5 out of 6 bidders went concrete and the concrete bid was 3%

lower than asphalt Low SY price was $48.45

RECENT ADAB PROJECTS

WV Corridor H, US 48 – 3.3 miles 4-lane arterial on new alignment – pre-graded 10” PCCP vs. 13.5” Asphalt Bid by the SY of Mainline Pavement 4 of the 5 bidders bid concrete and the low concrete bid

was 29% lower than asphalt Low SY price was $46.40

RECENT ADAB PROJECTS

US Route 35, Putnam County – 14.5 miles Design build – lump sum bid 4-lane arterial with structures on new alignment – grade,

drain, pave & structures Bid by the SY of Mainline Pavement 10” PCCP vs. 12.5” Asphalt Four proposers – 3 confirmed use of concrete pavement Successful team went with concrete

RECENT ADAB PROJECTS

WV Corridor H, US 48 – 6.0 miles Design bid build 4-lane arterial with structures on new alignment – grade,

drain, pave & structures Bid by the SY of Mainline Pavement 10” PCCP vs. 12.5” Asphalt Low bidder went with concrete Low SY price was $44.50

THE RESULTS

8 out of 9 projects went concrete when bid as an alternate to asphalt

On these projects about 80% of the bidders have bid concrete and all have had at least 4 bidders

WVDOH has saved $9,800,000 just on the four paving jobs alone over the low asphalt bids.

UPCOMING ADAB PROJECTS

1. Route 9 - Charlestown - VA line – 3.1 miles paving only

2. Corridor H - Rte. 1 to Mount Storm – 11.8 miles paving only

3. Corridor H - Mount Storm to Parsons - 10 miles grade, drain, & pave

Why ADAB “Works” in WV

WVDOH senior management support Strong new construction program Equivalent designs Economized PCCP design (no seal, no

dowels in shoulder, no cure on CTOGB Most asphalt work controlled by one

company
