1 November 2014 AEMA Fall Meeting Baltimore, MD

2 Insights to be Shared: The Agency need for Mastic Sealers
The Team working together Our Hypotheses and Results Manufacturing & Application Testing & Conclusions

3 The Agency Case for Mastic Sealers
Customer based Innovation: Extensive survey of Customers - “What did we not hear you tell us in the past?” Willing to trade some lifecycle performance for initial savings Needed to be easy and reproducible Target price around $1.00/Yard2

4 Agency Needs: Colorado Cost Inflation Case
Year PG 64-22 PG 76-28 HMA - S SMA 2006 $435 $448 $51 $61 2013 $480 $866 $68 $93 Percent Change 10% 93% 33% 52%

5 Need: An alternative low cost treatment
High Cost Fogseal .80 lbs yd2 $.75-$.85 Microsurfacing 18-25 lbs yd2 $2.25-$3.00 Thin lift HMA 85 lbs yd2 $3.50-$6.00 Sand Seal 12-15 lbs yd2 $1.50-$1.75 Mastic Sealer ~3 lbs yd2 $1.00-$1.25 Chip Seal/ Slurry Seal 15-18 lbs yd2 $1.50-$2.50

6 Mastic Sealer Team InVia & MWV Equipment Providers Agencies
Experienced team of asphalt technologists Experienced team of Chemists Invia is wholly owned subsidiary of MWV Equipment Providers Black Roads Bergkamp CPM Agencies City and Counties Large Agencies China Brazil Licensee Network Facilities throughout the US

7 Our Hypotheses Spray applied mastics will give superior performance while using less materials and less personnel. Innovation in the paving industry is needed to meet performance and cost requirements.

8 Manufacturing and Application
Plant Lay-out Application Equipment

9 Manufacturing

10 Application Sweep Mixing Storage New pumping for consistency
New Spray-bar technology for larger particles

11 Tests & Conclusions Modified Wet Track Abrasion Test Impermeability
Friction Projects

12 Mastic Results:Wet Track Abrasion
Notes: Test is based on ISSA- TB100 Analysis is based on 2014 projects 10 samples used in Lab 21 samples use in QA Specification Limit is 80 grams/m2 Loss

13 Impermeability Foundational value component of mastic sealer technology is the effectiveness in sealing the pavement from moisture intrusion. Compacted asphalt mixture is placed in the unit. a head of water is pumped through the specimen Our sample preparation: Coated top of specimen with Onyx-R1 Allowed sealer to cure Ran permeability test

14 Mastics Impermeability

15 InVia has been working with Texas Transportation Institute (TTI) to better understand Onyx performance. One of our test sections was evaluated using Ground Penetrating Radar (GPR). Background on GPR development in the U.S.: Technology Developed for SHRP 2 Equipment Manufacturer: GSSI, Inc. Provides real-time data processing Rapid field post-process to determine air void statistics

16 Onyx Treated Core Sections
Onyx Treated Section Onyx Treated Core Sections Untreated Section

17 Core Holes Holding Water
Unsealed Pavement Onyx Application Dielectric constant being steady in Onyx section indicates no moisture intrusion in the core holes. Unsealed section core holes indicates significant water intrusion.

18 Mastic Results: Friction
Test Sections were Placed at the Texas Transportation Institute Test Facility - Riverside Campus

19 Mastic Results: Friction
Skid Trailer used in Evaluation Dynamic Friction Test

20 Mastic Results: Friction
Mastic sealers on test section out-performed fog seals by 25% on skid trailer tests Mastic sealers on test section out-performed fog seals by 50% based on Dynamic Friction Tests

21 Conclusion: mastic sealers meet the need
Road projects placed since 2011 Over 16 Million Yards2 applied Millions of dollars spent in technology development Meeting Agency Needs through Innovation
