Island Voices – Amy C. Brown
I recently used my University of Hawaii researching skills to study Hawaii’s failing roads and busted the following myths:
» It’s a war on potholes.
False. Potholes are due to water seeping through asphalt coverings that crack due to thinness. Water partially dissolves the base underneath, causing the surface to cave in and create a pothole. Cracks, alligator skin where chunks pop out, and potholes are all signs that the road has “failed.” Other factors include traffic volume, vehicle weight, climate, subgrade support, material mix for asphalt and base, road design, construction quality, maintenance, etc.
