To promote a circular economy and sustainable development, the possibility of using lignin-rich industrial byproduct as partial substitute for asphalt emulsions in road pavements is analysed. A half-warm mix reclaimed (HWMRA)-type AC 16 surf S, manufactured with 100% pavement, selected. Substitution percentages 0% (control mixture), 5%, 10%, 15%, 20% are employed. The microstructure blend emuls...

Fatigue characteristics of asphalt binder have an important role in asphalt mix resistance against cracking. Viscoelastic Continuum Damage (VECD) analysis of asphalt binders has been successfully used in highway research works in order to predict fatigue behavior of hot mix asphalt (HMA). In this method an intrinsic property of the material, called damage function is obtained which is independe...

The Fremont Bridge is steel tied arch bridge over the Willamette River in Portland, Oregon. It carries traffic on Interstate 405 and US Highway 30 between downtown and north Portland. . The bridge was constructed in 1973, and the paving on the original steel deck consisted of epoxy asphalt concrete followed by an asphalt concrete overlay. The pavement performed for nearly 40 years before it nee...

In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...

Climate change has caused a surge in abnormal weather patterns, leading to rise cracks, plastic deformation, and pothole damage on road surfaces. In order fabricate ready-mix admixture of warm asphalt mixture (WMA) for restoration, this study aimed develop neutralized anti-stripping material pellet form by extruding combination slaked lime liquid emulsifier additive. Slaked (1% weight aggregate...
