1. Advantages & Benefits of Evotherm

3. Improved Compaction

5. TxDOT Densities 5% 3.2% 2.0% Evotherm is frequently used as a compaction aid to achieve density bonuses

6. NCAT Test Track Pavement Densities 200 220 240 260 280 300 320 340 % Density Compaction Temp (F) Evotherm Temp HMA Temp

7. Liquid Anti-Strip Replacement & Fiber Removal

11. Reduced Thermal Segregation

13. 62 Deg Difference

14. 24 Deg Difference

15. Extended Hauls and Paving Season

17. HMA at 50ºF HMA has only 19 minutes of paving time until the minimum compaction temperature is reached. 19 Minutes

18. Evotherm at 50ºF 35 Minutes Evotherm has 35 minutes until the minimum compaction temperature is reached. > 80% Increase in compaction time

19. Evotherm at 1ºF 21 Minutes It would have to be 1 °F outside for Evotherm to behave like HMA at 50 °F !

21. Increased usage of RAP

23. Increased RAP in Missouri I-44 in Eureka, MO near St. Louis 12.5-mm Superpave mix with PG70-22 binder Increased RAP content by 75% while maintaining mix properties. Excellent workability in the lab and in the field. RAP savings of $4 per mix ton! 3.48 3.49 DSR @ 70 C 26 32 MSCR 7.35 7.56 DSR @ 64 C 38 42 Ductility 25,900 23,500 Viscosity 29 28 Penetration HMA 20% RAP Evotherm 35% RAP

26. Reduced Fuel Consumption and Emissions

27. Lower Emissions Hot Mix

28. Lower Stack Emissions with Evotherm compared to HMA 200 °F Evotherm, 310°F HMA control

29. What is WARM? Hot Mix Even at 276 °F, fumes are still visible.

30. Fume Exposure compared to HMA ↓ 41% Evotherm Below Detectable Limits ↓

31. Longer Binder Life

32. Binder Hardening Reduced Oxidation with Evotherm

33. Aggregate Absorption Hot Mix Control TxDOT Cores After 1 Year

34. TTI Overlay Tester Results * Test stopped * *

35. TTI Overlay Tester Results - Limestone

37. The Evotherm Difference

41. Easy to Use, Lowest Temperatures, Proven Performance
