Determination of Lime in Hot Mix Asphalt

This project will support the ALF experiments. Lumps of undispersed lime were found in the aggregate bins beside the ALF. This raised some doubt about the actual lime content of the ALF lanes, which was supposed to be 1%. There existed no method for determining the lime content of asphalt. Litigation by a State Agency came to light during the study. The amount involved in the litigation was $55 million for a six-mile stretch of interstate highway. The litigation centered on whether or not the contractor put the required 1% of lime in the hot mix. It was deemed important enough to the industry to develop a method that could also be used by the US paving industry. The objective of this prohect is to develop a test method that FHWA could use to determine the actual lime content of the ALF test lanes and to develop a method that could be used by the paving industry to rapidly determine if lime was present in a hot mix and quantify the amount present.
