Evaluation of the Influence of Variation of Superpave HMA Mixtures Physical Properties on Pavement Performance
並列摘要
For numerous years, researchers have investigated hot-mix asphalt (HMA) plant production and the relationship between measured quality control/quality acceptance (QC/QA) parameters and field performance. After 12 years of service, this study presents a statistical evaluation of the relationship between HMA plant QC/QA data, roadway density, and field performance, as measured by international roughness index (IRI), rutting, and random cracking. Three Louisiana Superpave projects constructed in 1999 utilizing wearing and binder course mixtures were evaluated. Results indicated that, as Superpave Gyratory Compaction levels increased, roadway density variability increased. Generally, QC test results were less variable than QA test results and voids filled with asphalt (VFA) showed the highest variability between measured volumetric parameters. Statistical analysis indicated that the coarse aggregate portion (19.0 mm, 9.5 mm, and 4.75 mm sieves) and the 0.075 mm sieve had an effect on voids in the mineral aggregate (VMA), VFA, and air voids (Va). The percentage of asphalt cement significantly affected rutting and random cracking; the top size aggregate at or near the nominal maximum size aggregate, the 4.75 mm, and the 0.075 mm sieves had an effect on rutting, random cracking, and IRI for the HMA mixtures evaluated.
