Laboratory and Full-Scale Testbed Study in the Feasibility of Styrene-Butadiene-Styrene Asphalt Pavement Having Epoxy Resin and Crumb Rubber Powder

Conventional asphalt concrete pavements have deteriorated rapidly due to the current increased traffic and extreme climate impacts. In addition upgrading in construction quality, there is an urgent need expand utilization of modified binders improve road capacity safety. The proposed research aims combine epoxy resin (ER) crumb rubber powder (CRP) contents into conventional Styrene-butadiene-styrene (SBS)-modified binder not only reduce consumption normal but also promote usage recycled waste material practice. To cope with this objective, ER CRP were designed at 3% 5% by weight binder, respectively. Various laboratory tests performed evaluate performance mixtures (ERCRP), including Frequency Sweep Test, Multiple Stressed Creep Recovery, Dynamic Modulus, Semi-Circular Bending (SCB), Cantabro Durability Tests. Additionally, assessment pavement via field testbed was conducted through Falling Weight Deflectometer Ground Penetrating Radar. Overall, adding CRP, strain value control reference mix can be reduced up 31.8% 28.3% MSCR 0.1 3.1 kPa, dynamic modulus ERCRP-modified samples approximately 32,267 189 MPa, while mixture 28,730 105 MPa highest lowest frequency, respectively, indicating enhancement under repeated loads. Regarding SCB test results 0 °C, peak stress 4.75 specimens 4.2 noticing improved stress-bearing capacity. Based on a full-scale testbed, FLWD elastic reinforced shows novel improvement (6.75%) compared pavement, suggesting potential application for sustainable development purposes.
