AsphAlt/ConCrete Roads That Go In The Night Roads and lots need regular maintenance to keep them safe for drivers. An asphalt speed bump added during reconstruction assists unattended traffic control. By Lance Luke N othing lasts forever, including public and private roads. The sun, wind and rain-weapons of mass destruction-combined with high traffic usage and poor maintenance can equal costly repairs or even total replacement. But maintaining and repairing your roadways and parking areas do not have to be a pain in the asphalt. The solution to avoiding costly repairs is continual maintenance, achieved through proper inspection and monitoring. Look closely along your roadway or parking areas for signs of change and damage. The original construction of the surfaces might have been improperly performed, or the ground may have settled over the years, creating low spots and poor drainage. Small trees planted close to the road may have grown quite large over the years, and the roots may be cracking and lifting the asphalt. Cracks may have expanded, and now water is penetrating into the sub-base material, causing an even bigger problem. In areas with this much damage, crack sealing or sealcoating is not 14 June-July 2014 BMH The solution to avoiding costly repairs is continual maintenance, achieved through proper inspection and monitoring. going to help. When small sections of asphalt have sunken or come loose, potholes will appear. You're going to need to reconstruct these damaged segments. The proper protocol on these spot repairs would be to have a contractor mark each area; saw cut, excavate and dispose of the material; compact and add additional base course as needed; then install and compact new 2-inch asphalt pavement, generally with SS-1H prime (an asphalt binder). Beware of the fast "throw and roll" job, where the pothole is just filled with new asphalt and rolled over with a truck. If you've got invasive tree roots upending your asphalt, they'll need to be cut out and removed. In certain cases, a root barrier will need to be installed so that they don't grow under the asphalt again. In addition, it's important to verify drainage areas, especially at roadways and transitions to existing drains. Due to soil conditions, drains and curbs may be higher in elevation than the road, creating an improper drainage condition. Your contractor should also confirm all elevations and may have to revise as-built conditions for proper water flow and drainage. During a reconstruction job, you may want to add additional speed bumps made of asphalt. Be sure you specify the type of mix. Generally the State Mix #5 is used. The mix numbers follow the HAPI (Hawaii Asphalt Paving Industry) Asphalt Pavement Guide.
