  14. Comparison

  15. The difference AR Seal Coat makes

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

  17. Texas Experience with AR Seal Coat • Firstuse 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

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

  20. Eight year old Seal Coat

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

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

  24. Another bleeding Seal Coat

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

  26. 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

  27. 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
