• Abstract:
  Researchers investigated the effect of several influencing factors on the performance of precoated aggregates in seal coats based on a thorough literature review and a survey of TxDOT and other state DOT personnel. Researchers evaluated tests that measure the area of surface coating on precoated aggregate and determined that an image analysis technique performed best. They also determined that a lab Sweep test and Vialit test were the best candidates to measure adhesion of aggregate in seal coats. They used these tests to evaluate the influencing factors on aggregate adhesion in a set of laboratory experiments.
