A case study of the comparison between rubberized and polymer modified asphalt on heavy traffic pavement in wet and freeze environment

Ground tire rubber (GTR) usage in asphalt pavement with the dry process has gained more prominence recent times. The objective of this work is to investigate performance GTR-modified and polymer-modified on heavy volume traffic conditions Michigan's wet freeze environment. A suite laboratory tests was done evaluate mixtures. To reveal strain stress relationship under different frequencies temperatures, dynamic modulus test applied. Hamburg wheel tracking device (HWTD) used assess high-temperature deformation resistance. disc-shaped compact tension (DCT) low-temperature cracking characteristics. characteristics binder were assessed by shear rheometer (DSR) for properties (ABCD) properties. After construction, a field noise conducted. experimental results stated that mixture showed higher better ability prevent than conventional at low as well permanent stripping resistance mixture. fracture energy hot mix (HMA) 13%-16% larger HMA. number passes point 510%-518% When compared core, lab-compacted HMA offers superior performance. extracted show rutting asphalt, demonstrated rubber-modified mitigated level 2-3 dB road vehicle speeds. Moreover, condition noticeably enhanced after reconstruction surface course. total passenger tires be project about 2,270. summarize, are shown project's utilization technology. And comparable Therefore, it may appropriate utilize technology high-traffic climate.
