• Abstract:
  Pavement surfaces must maintain an adequate level of friction in order to provide a ; safe surface for vehicles. The Maryland State Highway Administration (SHA) is ; responsible for ensuring that flexible pavement construction, using hot mix asphalt ; (HMA), meets approved skid resistance standards, by selecting surface mix aggregate ; with adequate frictional and durability characteristics. Conventional aggregate testing ; methods are however, laborious, time‐consuming, and expensive. This research ; proposed to develop faster, accurate, cost‐effective, and nondestructive ; methodologies that utilize spectral properties and characteristics of aggregate samples ; such as their wavelength and reflectance to assess and evaluate HMA surface mixes.
