Evaluation of HMAC Longitudinal Joint Construction in Louisiana

The primary objective of this research is to evaluate the influence of tack coat material type on the resulting longitudinal joint density and permeability. A secondary objective is to ascertain the relation between the interlayer bond shear strength and the quality of the longitudinal joint as measured by density and permeability. This research will evaluate the unconfined edge area including the longitudinal joint, in regards to density and permeability, using an un-modified emulsion (SS-1) and a polymer modified emulsion (CRS-2P) as the tack coat material types to determine the influence of these tack coats in regards to density and permeability transversely from centerline of the cold mat to centerline of the hot mat.
