Technical Brief on Using New Pavement Design Procedures for Hot Mix Asphalt Mixtures Modified with Hydrated Lime

An overview for highway pavement engineers and managers of a study of whether mechanistic-empirical Design Guide procedures can be used for lime-modified asphalts.  The results demonstrate that evaluating asphalt mixtures containing lime will not require any new, separate, or special test protocol or analysis techniques.  Mixtures containing lime exhibited an overall 25 percent average increase in stiffness — the primary material property measure used in the Design Guide.  (4 pp)
