METHODS AND PARAMETERS FOR THE USE OF EMULSIFIED ASPHALTS FOR PRIME COATS AND BINDERS FOR OPEN GRADED ASPHALTIC CONCRETE FINISHING COURSES

The study is divided into two phases. Phase I investigates the use of Emulsified Asphalts for Prime Coats and Phase II investigates the use of Emulsified Asphalts as Binders for Open Graded Asphaltic Concretes. During Phase I, several sets of aggregate based specimens were "primed" with various grades of Emulsified Asphalts with a device fabricated for the study. This provided sufficient data to make recommendations for the use of a CMS-2S grade Emulsified Asphalt as a suitable prime coat. In Phase II, attempts were made to determine the emulsion drainage properties and coatability of the Emulsified Asphalt and to determine the durability of mixtures comprised of Emulsified Asphalt and three types of aggregates, regarded to meet local specifications for open-graded asphaltic concrete finishing courses. The three aggregate types were a local natural aggregate, a synthetic aggregate and a volcanic cinder.
