Asphalt Emulsions for Highway Construction (FHWA Demonstration Project 55)

摘要

This report covers the design, construction, and post construction evaluation of an asphalt emulsion seal coat (single surface treatment) on a high volume, high speed interstate highway. A bituminous seal coat consisting of E-3 (AASHTO CRS-2) asphalt emulsion binder and bituminous precoated 1B sandstone aggregate 'chips' was placed on Interstate 81. Results are presented which indicate the successful performance of this seal coat for 3 years until reconstruction of the roadway.
