Evolution of Alternate Design Alternate Bid (ADAB) Procedures Joint efforts began in the Fall 2007 including WVDOH, FHWA and industry. Formal procedures implemented in July 2008 All procedures finalized June 2010

CORRIDOR H – US 48 MOOREFIELD (July 2008) First “formal” Alternate Bid pavement project 10.6 miles 4-lane arterial No life cycle cost adjustment (C factor) Included asphalt escalator Asphalt by the ton and PCCP by the SY

CONCRETE PAVEMENT DESIGNDescription: Perpetual pavement design provided by Industry using Westergaard Equations Design 10” Jointed Plain Concrete Pavement on 4” free draining base 15’ doweled joints Full depth tied concrete shouldersAssumptions: Analysis period = 50 yrs Initial performance period = 22 yrs Rehab performance period for CPR = 14 yrs Rehab performance period for Overlay = 14 yrs No Salvage value @ year 50 Rehab #1 – diamond grinding and 7.5% joint patching Rehab #2 – overlay w/2” skid resistant mix w/PMA and 2% joint patching10” Jointed Plain Concrete Pavement 4” Free Drain Base Pavement Typical

ASPHALT PAVEMENT DESIGNDescription: Perpetual pavement design provided by Industry using PerRoad 3.2 Design Program 13.5” HMA on 4” free draining base Use PG 76-22 polymer modified asphalt (PMA) binder in top 4.5” and on future overlays Increase AC by 0.5% in bottom 5”Assumptions: Analysis period = 50 yrs Initial performance period w/PMA = 22 yrs Rehab performance period w/PMA = 14 yrs No salvage value @ year 50 Rehab #1 – mill and resurface w/2” skid resistant mix w/PMA Rehab #2 – mill and resurface w/2” skid resistant mix w/PMA2” 12.5mm skid w/76-22 AC 2.5” 19mm mix w/76-22 AC 4” 25mm mix w/64-22 AC 5” 37.5mm mix w/64-22 AC + 0.5% AC content 4” Free Drain Base Pavement Typical

SECTION 690 MAINLINE PAVEMENT 690 – GENERAL 690.1 - DESCRIPTION: This Special Provision shall define the requirements to construct mainline pavement, which includes roadway pavement and full depth paved shoulders, to the limits as shown by the contract plans. The contractor shall construct one of the pavement systems as described herein and by the contract plans.

8

CONCRETE PAVEMENT SYSTEM: A concrete pavement system shall be constructed as defined by the concrete typical section(s) and all other documents referenced in the contract plans. This work and materials shall include jointed plain concrete pavement, free draining base, fabric for separation, subgrade, and subgrade preparation ASPHALT PAVEMENT SYSTEM: An asphalt pavement system shall be constructed as defined by the asphalt typical section(s) and all other documents referenced in the contract plans. This work and materials shall include asphalt wearing surface, asphalt base courses, free draining base, fabric for separation, subgrade, and subgrade preparation. .

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

10

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

13

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

14

THE RESULTS8 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.

15

UPCOMING ADAB PROJECTS Route 9 - Charlestown - VA line – 3.1 miles paving only Corridor H - Rte. 1 to Mount Storm – 11.8 miles paving only Corridor H - Mount Storm to Parsons - 10 miles grade, drain, & pave

16

Why ADAB “Works” in WVWVDOH 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

17

FALLOUT INTERESTOne new CPR projects is complete with 2 more about to come out Concrete was bid as an alternate on an asphalt overlay job The WV Turnpike is looking at concrete overlays instead of just asphalt Extensive statewide concrete pavement training requested and delivered Concrete is no longer a “four-letter word” – ACPA’s phone is ringing!
