• Abstract:
  This test method is almost identical to "The Net Adsorption Test for Chip Sealing Aggregates and Binders" developed by Walsh et al. (1995). This test method developed by Walsh et al. to evaluate the compatibility between seal coat aggregates and binders was based on a similar method developed for asphalt-aggregate systems in general, by Curtis et al. (1993). Both test methods indicated above include an asphalt adsorption phase (on the aggregate surface) from an asphalt-toluene solution and an asphalt desorption phase from the aggregate surface in the presence of water (i.e. stripping), which is considered as a measure of the strength of bond between the two materials. It is suggested that the percent net adsorption calculated as proposed by Curtis et al. (1993) be used to evaluate the appropriateness of an asphalt to precoat a particular surface treatment aggregate.
