Carbon Black Additive In Asphalt: SR-290, Spokane Vic. [i.e. Vicinity], Flora Road to Idaho State Line

Description: This report describes the construction of an experimental section of asphalt concrete pavement overlay which contained the additive carbon black. A long term evaluation of the overlay seeks to determine if there is a significant difference in performance between it and an adjacent control section of pavement which contains no additive.

Preliminary laboratory results indicate that the viscosity/temperature curve for the carbon black asphalt binder has been altered in a way that the temperature susceptibility of the pavement is decreased.
