The mix design and testing procedures outlined in this publication are intended to help ensure the long term strength and durability of lime stabilized soils that specifying agencies, design engineers, and laboratory personnel can use with confidence for soil conditions and environmental exposures throughout the United States.  These procedures are based on a series of […]

Short technical paper summarizing research that demonstrates the multifunctional benefits of lime in asphalt.  (15 pp)

Gary Hicks & Todd V. Scholz:  Uses methodology recommended by the Federal Highway Administration to evaluate lifetime costs of different pavement designs.

An introduction to proven and effective methods used to add hydrated lime to asphalt to reduce stripping and enhance performance (14 pp, 1.3 MB)

Dr. M. W. Witczak and Javed Bari:  This study demonstrates that the standard test and design methodologies in the new NCHRP mechanistic-empirical (M-E) pavement design guide entitled, 2002 Design Guide:  Design of New & Rehabilitated Pavement Structures, can be used effectively for lime-modified asphalts. Using the new M-E pavement design guide methodologies, hydrated lime was found […]

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 […]

Fact sheet that summarizes the multifunctional benefits of lime in asphalt.  (4 pp)

By Peter E. Sebaaly, Dallas N. Little & Jon A. Epps:  Comprehensive literature review of the multi-functional benefits of lime in asphalt:  reduce stripping and water sensitivity; increase mix stiffness and reduce rutting; diminish oxidation and age-hardening effects; and improve low-temperature cracking resistance.  The benefits of lime are demonstrated by laboratory testing, mechanistic-empirical models, field […]

Provides an in-depth analysis of recent research comparing lime vs. liquid antistrip additives in reducing moisture sensitivity of Hot Mix Asphalt (HMA) mixtures.  Includes a discussion of the behavior of HMA pavements such as strength and resistance to rutting, cracking, and fatigue and how research results relate to pavement performance.  Demonstrates that lime-treated asphalt is […]

Detailed results of a two-year study of lime and liquid treated asphalt from five states.  Typically, lime and liquid are used as additives to combat moisture damage.  This study extended the evaluation to cover the impact of lime and liquid additives on the structural performance of the HMA mixtures and their impact on the long […]
