Performance Characterization of Recycled Asphalt Pavements with Warm Mix Asphalt Technologies
… characteristics of Recycled Asphalt Pavements (RAP) with Warm Mix Asphalt (WMA) Technologies. RAP was introduced in mixtures at three levels: 0, 15 and 35% of RAP contents. Five WMA technologies were evaluated against all the mentioned levels of RAP content. The study was conducted in two …

Effects of Reclaimed Asphalt Pavement on Mechanical Properties of Base Materials
<p>Reuse of reclaimed asphalt pavement (RAP) in the full-depth recycling (FDR) process is a cost-effective and environmentally responsible method of asphalt pavement reconstruction. Although FDR has been used for several years in some locations, the effect of RAP on the mechanical properties of …

Impact of reclaimed asphalt pavements on pavement sustainability
… construction. Reclaimed asphalt pavements (RAP), being a source of aggregates and asphalt binder, is the most recycled material in the U.S. However, incorporating high amount of RAP in asphalt mixtures can pose significant mix design issue and could compromise the pavement performance. …

Contractor Variability in Construction of Cement Treated Base Layers
… I-84 sites include reclaimed asphalt pavement (RAP) content; cement content; amounts of aggregate particles finer than the No. 8, No. 50, and No. 200 sieves; 7-day moisture content, and 28-day moisture content. The significant predictors of the same response variables on US-91 were in-situ …

Cement Stabilization of Aggregate Base Materials Blended with Reclaimed Asphalt Pavement
… the effects of reclaimed asphalt pavement (RAP) content and cement content on the strength and durability of recycled aggregate base materials. Specifically, the unconfined compressive strength (UCS) and final dielectric value in the Tube Suction Test (TST) were measured in a full-factorial …

Quantification of the Role of The Effective Binder in the Performance of RAP – WMA Mixtures
… several new technologies/materials (such as WMA, RAP, rubber, polymers, bio-binders…etc.) were incorporated into asphalt mixtures. However, current mix-design specifications evaluate all mixtures containing these different additives/technologies based on volumetric. Further, RAP incorporation in …
