7 MUST HAVE PROPERTIES OF ASPHALT CONCRETE - CivilBlog.Org

Stability of an asphalt pavement is its ability to resist shoving and rutting under loads (traffic). A stable pavement maintains its shape and smoothness under repeated loading; an unstable pavement develops ruts (channels), ripples (wash boarding or corrugation) and other signs of shifting of the mixture. Because stability specifications for a pavement depend on the traffic expected to use the pavement, the requirements can be established only after a thorough traffic analysis. Stability specif
