• Abstract:
  The primary objective of this project was to develop a test for measuring the bond strength ; between pavement layers. The research was also to evaluate tack coat materials and application ; rates for the Alabama Department of Transportation (ALDOT). The project included a laboratory ; phase and a field phase. For the laboratory work, the experiment included two types of emulsion ; (CRS-2 and CSS-1) and a PG 64-22 asphalt binder that are allowed by ALDOT’s specifications. ; Bond strengths were measured with a shear type device at three temperatures and three normal ; pressure levels. Three application rates that encompassed the specification range were ; investigated for each tack coat. Laboratory prepared mixture samples included a coarse-graded ; blend and a fine-graded blend to represent two different surface textures. The effects of tack coat ; type, application rate, mixture type, testing temperature and normal pressure on the bond strength ; were evaluated.
