  • Shorter life span than HOT crack fill
  • Shorter life span than HOT crack fill
  • Hot crack fill will penetrate crack better and will expand and contract with varying temperatures. Cold crack fill is less pliable than hot crack fill and will not expand with the pavement and may crack.
  • Hot crack fill will set faster than cold crack fill. Vehicles can drive over it sooner.

    9. 9. common causes of asphalt damage here in Hawaii.5 There are
    10. 10. UV Rays 1.
    11. 11. UV rays break down the binder that holds the rock, sand, & aggregates together.
    12. 12. Oxidation 2.
    13. 13. Oxidation The interaction between oxygen molecules and all the different substances they may contact.
    14. 14. Oxidation In general, oxygen molecules cause asphalt molecules to bond tighter, creating a stiffer, more brittle pavement.
    15. 15. OXIDIZED ASPHALT IS GRAY NEW ASPHALT IS BLACK
    16. 16. Water 3.
    17. 17. Image Credit: yaybiscuits123 If water is allowed to penetrate into your base through cracks, your asphalt becomes more prone to cracks and potholes.
    18. 18. Underground drainage issues can also cause damage to your base course.
    19. 19. Traffic Load 4.
    20. 20. Heavy vehicles like garbage trucks put enough stress on your asphalt to cause cracks.
    21. 21. Poor compaction can also cause loading issues.
    22. 22. Oil Stains 5.
    23. 23. Oil stains eat away and softens your asphalt until the pavement cannot carry traffic load.
    24. 24. What to do?
    25. 25. Here’s 6 asphalt repair & maintenance options
    26. 26. and we’ll compare DIY options to hiring a pro.
    27. 27. Sealcoating 1.
    28. 28. A sealcoat acts as a barrier to protect asphalt from oxidation, UV rays, oils, water penetration, & salts.
    29. 29. Before sealing your asphalt, the surface must be prepped.
    30. 30. Debris must be removed from the surface.
    31. 31. Vegetation must also be removed from the asphalt.
    32. 32. Large areas that need prep can be a pain unless you have special equipment.
    33. 33. Applying the sealcoat yourself is manageable for small areas.
    34. 34. But imagine applying a sealcoat to a large area.
    35. 35. Specialized equipment can make the job easier.
    36. 36. Crack Fill 2.
    37. 37. Filling cracks in your asphalt will prevent water penetration.
    38. 38. There are two types of crack fill: COLD & HOT.
    39. 39. Image Credit: Home Depot Cold crack fill is relatively easy to apply and requires minimal equipment.
    40. 40. Image Credit: Home Depot DIY is a possibility depending on lineal feet.
    41. 41. Hot crack fill is more pliable than cold crack fill and will penetrate the crack better.
    42. 42. It also sets quicker– allowing vehicles to drive over sooner.
    43. 43. However, hot crack fill must be heated to 300°F-400°F before being applied.
    44. 44. Hiring a contractor may be more convenient for larger scopes of work.
    45. 45. Pothole Repair 3.
    46. 46. Repairing a pothole will prevent additional water from penetrating your asphalt.
    47. 47. Pothole patches will “plug” the hole.
    48. 48. But higher quality patches will also prevent water penetration into the asphalt.
    49. 49. Pothole patches are DIY and provide temporary relief.
    50. 50. However, a pothole is a result of a base course failure. Patches do not address the base course. Image Credit: HAPI
    51. 51. A permanent solution would require hiring a contractor.
    52. 52. The contractor would melt/soften the asphalt.
    53. 53. Then dig out the asphalt.
    54. 54. And replace with new asphalt.
    55. 55. And finally recompact.
    56. 56. Remove Oil Stains 4.
    57. 57. DIY oil stain removers “suck” up the oil from the asphalt.
    58. 58. Apply, give time to dry, then scrub off.
    59. 59. However, drying time can vary from 5 to 8 hours.
    60. 60. And the longer oil stains go untreated, the more difficult they are to remove.
    61. 61. Hiring a contractor can expedite the process.
    62. 62. Using the same method as permanently repairing a pothole.
    63. 63. 5. Traffic Load
    64. 64. DIY- Move dumpsters near your parking lot entrance to prevent garbage trucks from entering your parking lot.
    65. 65. Or you can hire a contractor to install a concrete pad near your dumpster to carry the load of garbage trucks.
    66. 66. 6.Striping & Marking
    67. 67. Using paint brushes and rollers might be easy enough if you were touching up old lines.
    68. 68. Stencils are also useful for DIYers.
    69. 69. But if you’re starting from scratch, that’s when hiring a contractor may be helpful.
    70. 70. Striping straight lines with a brush or roller can be difficult…
    71. 71. Striping straight lines with a brush or roller can be difficult… …and may not look as professional.
    72. 72. Applying straight lines using a striping machine is easier than using a brush.
    73. 73. Also, you need to make sure you are following ADA parking lot guidelines.
    74. 74. For example, you need the appropriate amount of Accessible Parking Spaces.
    75. 75. And you need the correct signage.
    76. 76. In large scopes of work, hiring a contractor would be beneficial.
    77. 77. In summary:
