1 Sustainable Engineering with In- Place Recycling Technologies The Road To The Future Strengthening or Recycling Existing Materials In-Place Instead of Costlier Removal/Replacement (R&R) Methods. Craig Harrington Pavement Recycling Systems

2 Since the 1930 s we have been doing the same thing, remove and replace (R&R) Old asphalt is removed and replaced with new asphalt Entire pavement sections are removed and replaced with new aggregate base and asphalt.

3 Construction Methods For Asphalt Pavements Have Evolved! Cold In-Place Recycling (CIR)- recycles old asphalt into new base course on jobs with adequate base/subgrade conditions Cold Central Plant Recycling (CCPR)- For projects inaccessible to train with/without base/subgrade failures Full Depth Reclamation (FDR)/Soil Stabilization- Strengthens Existing Materials

4 Why? Typically a 30% to 50% total project cost savings of taxpayer dollars. Shortened construction schedules by up to one half. Less disruptions for residents/bus./traffic GHG and Energy Reductions No sacrifice to design life or structural integrity.

5 Proven, Soundly Engineered, Competitively Bid Processes Europe is 10 years ahead of U.S. in Implementing these recycling strategies In use across the U.S. for more than 30 years More than 150 CA. agencies have employed one or more in-place recycling process.

6 Factors Driving The Need To Evolve, Shrinking budgets Increasing trucking/fuel costs Failing infrastructure Scarcity and reduced quality of aggregate resources Mandate to reduce greenhouse gas emissions The need to adopt smarter and more sustainable practices! and Recycle

7 There Are Economic And Environmental Benefits In Re-Using Existing Materials/Assets Already In-Place And Paid For 2014 CA. Needs Assessment Report says by conservative estimates agencies can save $912 million/year and increase the paving budget by 55% by reusing or recycling existing materials, compared to conventional mill and fill overlays and reconstruction. Be the economic and environmental hero for your agency!

8 Overcoming The Status Quo Agencies and owners need to insist their design engineers provide them with their in-place recycling alternatives. That is what you are paying them for!

9 Recycling Existing Asphalt Into New Base Course Asphalt Sections In- Place/On-Site Cold In-Place Recycling (CIR) with the Recycling Train. (Arterials, Collectors, Highways, Runways) Cold Central Plant Recycling (CCPR) with a portable stationary plant (urban quarry) (Parking Lots, Residential Streets)

10 Before and After CIR

11 Far Less Disruptive to Traffic/Residents/Businesses Because of High Production And Quick Opening to Traffic * After rolling is completed. Generally after some cure (2 hours). After the fog-seal and sand blotter has been applied. After signs are furnished and placed adjacent to both sides of the traveled way where recycling operations are being performed.

12 CIR/CCPR Case Projects City of Moreno Valley City of Beverly Hills City of Palm Desert

13 Moreno Valley Energy And Cost Savings 8,744 tons of asphalt removed and repaved 840 fewer trucks used doing CIR, compared to a mill and fill operation. 1,649 fewer barrels of oil saved doing CIR. 79.6% fewer carbon emissions doing CIR compared to a mill and fill operation. Cost savings to City of $262, on $650,000 dollar project 30% Reduction in Const. Schedule

14 City of Beverly Hills Canon Dr., Beverly Dr., Crescent Dr., and Lomitas Ave. City saved $1.5 million 3 CIR with a 2 RHMA cap Took 2,600 trucks off city streets Zero windshield claims

15 City of Palm Desert Residential Streets 2010

16 Palm Desert Results Traditionally had been repairing failed asphalt sections with fabric and thin 1.5 overlays. Rate of deterioration and increased costs of overlays (approx. $2.50/SF) became cost prohibitive. CCPR process provided a brand new and stronger pavement section for under $2/SF, with a 20 year design life!

17 Performance Expectations Life Expectancy years minimum Restores old pavement Restarts design life

18 CIR is Green : Recycling In-Place Materials Saves Resources and Money Reduces import-export from 83 truckloads to 2 trucks (each truck equates to destructive effect of 10,000 cars) Fewer emissions, less truck traffic = 80% smaller carbon footprint Structural value and long life: resists reflective and thermal cracking

23 Full Depth Reclamation (FDR) More economically and environmentally sound alternative when complete reconstruction of the entire pavement section of a road or parking lot is needed. Strengthens Existing Materials In-Place

24 By Preserving and Strengthening In-Situ Materials, We Make Recycled Better Than New Superior structural sections at lower cost, in less time, by using what s already there Less environmental impact. Longer lifecycle, lower maintenance

33 City of Santa Ana Results of In-Place Recycling City of Santa Ana started out with a $100 million dollar budget to do 100 lane miles of street reconstruction. With In-Place Recycling they ended up doing 260 miles of street reconstruction, while only spending $70 million, and doing it all 2 years ahead of schedule!
