• Abstract:
  These guidelines derive from Texas Department of Transportation (TxDOT) Project 0-5091 and Report 0-5091-3. Replicate cores of both treated and untreated highway and general aviation pavement sections were analyzed in this extensive study. Whole cores were assessed by water permeability and by susceptibility to permanent deformation. Replicate cores were sawed into approximately one-quarter-inch slices that were individually analyzed for total air voids, accessible (or interconnected) air voids, binder content, oxidative aging and rheology, and the presence of fog seal material. The fog seal materials used in this project were emulsions of asphalt materials and coal tar type materials typically used by TxDOT. No assessments were made of the effect of the treatment on raveling of a recently placed seal coat or to the appearance of the pavement.
