The use of cold recycled asphalt mixtures (CRM) has been soaring during recent years. Reclaimed Asphalt Pavement (RAP) is the main component CRM, and despite numerous studies on impact different RAP types not deeply studied. This study compares volumetric several mechanical properties CRM prepared with from two sources various nominal maximum sizes (NMS). mix design was fixed, specimens were us...

This paper describes physical and mechanical properties of porous asphalt mixtures with various RAP amount (0%, 10%, 20%, 30%) containing one WMA additive (organic wax). The samples were prepared using the Marshall compactor at two different temperatures (125 °C, 145 °C) by fabricating six series mixtures. Air void content, particle loss, stiffness modulus, indirect tensile strength, strength r...

Sustainability and durability are the key requirements of pavement structure. asphalt structure involves utilization Warm Mix Asphalt (WMA) technologies with addition Reclaimed Pavement (RAP), where performance parameters like fatigue fracture resistance properties etc. Utilizing RAP content in mix increases mixing compaction temperature which may degrade asphalt. Hence, numerous studies have r...

Reclaimed Asphalt Pavement (RAP) has been extensively studied for potential use as a recycled material in infrastructure construction. There is consensus that utilization of RAP provides environmental and economic benefits most projects. However, impacts to engineering performance are less known, owing the highly variable nature sources with different asphalt pavement mixtures milling processes...

The intermediate-temperature performance of extracted asphalt binders (EABs) is altered when recycled shingles (RAS) and/or reclaimed pavement (RAP) are included in mixes. This happened as a result the RAP’s aged binder and RAS’s oxidized air-blown asphalt. Thus, rheological properties EABs from field cores were examined at intermediate temperatures. fatigue life Superpave cracking parameter am...

Reclaimed Asphalt Pavement (RAP) is the residual waste of pavement that has been damaged or reached end by using a Cold Milling Machine (CMM). The old aggregate undergoes gradation changes due to traffic loads and weather effects so not following ideal plan. addition natural aggregates aims improve grading envelope meet upper lower limits AC-BC layer requirements. This study determine optimal c...
