• Abstract:
  The objective of the study is to improve Oklahoma Department of Transportation (ODOT) chip ; seal design and performance through introducing new criteria for the selection of cover ; aggregate and binder. These criteria will be based upon the recent technological advances in ; the characterization of aggregate shape and texture as well as aggregate-binder compatibility. ; The study evaluates the shape and texture-related index properties, as well as durability, of ; commonly used cover aggregates in chip seal programs in Oklahoma. Additionally, it will ; provide a methodology for inclusion of these characteristics as a metric in future chip seal ; specifications. The study includes both laboratory testing and construction and performance ; evaluation of chip seal test sections. The study is ongoing and is quantifying how well the ; newly developed performance-based uniformity coefficient (PUC) correlate with chip seal ; performance in Oklahoma, and if it should be incorporated into state chip seal specifications. It ; has generated aggregate-binder compatibility data, based on the surface free energy ; (compatibility ratio) approach, for commonly used aggregates and asphalt emulsion binders in ; Oklahoma. Moreover, the chip seal construction practice followed by different ODOT ; Maintenance Divisions was documented and the best practice identified. This repository of ; information will be a useful resource for ODOT maintenance divisions.
