16. Comparison

17. The difference AR Seal Coat makes

18. A good candidate for AR Seal Coat: Lots of cracks, but structurally sound.

19. Texas Experience with AR Seal Coat First use was in 1976 in Bryan and El Paso districts Between 1976 and 1981, 850 miles of AR seal coat was placed By 1990, 2,000 lane miles of AR Seal Coat was placed More than 20 districts have placed AR Seal Coat since 1976 in 70 counties

21. US 90, crack disappearing in 10 year old Seal Coat

22. Eight year old Seal Coat

23. Seal Coat on IH-10 near Van Horn Five years old

24. Seal Coat on IH-10 near Van Horn Five years old

25. Not all AR Seal Coats Turned out good Grade 4 Seal Coat

26. Another bleeding Seal Coat

27. Smaller grade 4 Aggregate will sink into the AR Binder

28. Performance of AR Seal Coat Experience has mostly been satisfactory Good construction practices are a must! - Clean or pre-coated aggregate - Chip spreader staying close to distributor - Adequate curing of AR - Correct binder shot rate and aggregate rate

29. Performance of AR Seal Coat Shot rate must correspond to aggregate top size: - Grade 3 vs.. Grade 4 aggregate - Earlier problems with flushing were most likely due to aggregate size
