Abstract:

Water sensitivity of asphalt concrete pavements is of great importance nationwide. Water-sensitive pavement may suffer damage that leads to reduced pavement life when subject to moisture. To alleviate this problem, various liquid antistripping additives have been developed. In this paper are presented the results of a study on the effectiveness of antistrip additives for materials used in the reconstruction of Nevada State Highway 207. Preconstruction mixtures containing various antistripping additives (liquids and solids), construction mixtures mixed in the field and compacted in the laboratory, and cores taken after construction were subjected to laboratory conditioning using vacuum saturation plus one cycle of freeze-thaw. Test results show that a slight reduction in water sensitivity was obtained in mixtures that contained the liquid antistrip additives in comparison with control mixtures without additives or mixtures containing portland cement as an antistripping material. Results of evaluation of mixtures during the preconstruction phase of the project indicate that mixtures that contain lime slurry exhibited significant reductions in water sensitivity. Test results of field cores show agreement with preconstruction mixtures in the prediction of water sensitivity. Test results of cores also indicate that no significant changes in mixture strength and water sensitivity have taken place during the first year of life. In addition, visual surveys have indicated that test sections that contain either the liquid antistripping additive or portland cement additive have performed well during the first year of pavement life.
