Evaluation of Rutting Resistance of Superpave and HVEEM Mixtures Volume 2: Impact of Aggregate Gradations;Research rept

摘要

This report represents the second in a series of four reports documenting the overall evaluation of rutting resistance of Super pave and Hveem mixtures. Specifically this report documents the evaluation of the impact of aggregate gradation on the permanent deformation resistance of HMA mixtures using the RSCH test. This experiment was developed using materials from NDOT contracts 2751 and 2827 which were originally constructed in the falls of 1996 and 1997, respectively and are fully described in Volume 1 of the report series (1). Both contracts included test sections using a Hveem and a Superpave designed mixture to compare their performance under similar traffic and environmental loading conditions.
