Cracked and deteriorated asphalt are common problems on our roads, leading to safety concerns requiring significant resources for rehabilitation reconstruction. This study investigates bio-fog seals, a promising eco-friendly solution utilizing bio-based rejuvenators. These treatments penetrate aged asphalt, restoring its flexibility resistance cracking. We assessed the effectiveness of two seal formulations—one containing sub-epoxidized soybean oil (SESO) other combining SESO with biopolymer...
In this study, asphalt mixtures were engineered with bio-renewable soybean oil-derived modifiers, and then used for pavement demonstration projects in the U.S. states of Iowa Minnesota summer 2019. The performance grade, elastic recovery (R), non-recoverable creep compliance (J nr ) binders evaluated. modification binder project almost maintained high low temperature grades, presence modifier mixture resulted a slight decrease grade while maintaining grade. J R values proved increase...
In this study, an asphalt binder was modified with epoxidized methyl soyate (EMS) that engineered at Iowa State University. The modification accomplished in terminal, and the resulting used for reversing undesired effects of reclaimed pavement (RAP) a mixture containing 30% material. produced plant demonstration project occurred November 2017. EMS-modified RAP control only 18% were paving 7-mile stretch high-volume roadway O'Brien County, Iowa, U.S. About 6.6 miles paved low is traditionally...
