A Procedure to Quantify Organic Antistrip Additives in Asphalt Binders and Mixes

CODEN: JTEVAB

Abstract

Stripping is a phenomenon of loss of bond or adhesion between the asphalt binder and the aggregate in asphalt mixes. Stripping frequently results from the presence of water, and most agencies require the use of antistrip additive to control moisture damage. However, there is no simple and quick method for detecting the presence and the amount or percentage of organic antistrip additive in asphalt binders or mixes. This paper presents a procedure based on solid-state spectrophotometry to detect qualitatively and quantitatively the presence of amine-based antistrip additive in asphalt binders and mixes. The developed procedure gives results that are quantifiable and reproducible with low coefficients of variation.
