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...

This report presents the results of an investigation of the performance of a variety of materials added to asphalt binders and mixtures to change their properties, particularly with respect to rutting and cracking. The approach included a field trial of seven polymer and particulate modifiers, supplemented by laboratory characterization of the materials used in the field. The modifiers evaluate...

Over the last decade, unexpected and sudden pavement failures have occurred in several provinces in South Korea. Some of these failures remain unexplained, further illustrating the gaps in our knowledge about binder chemistry. To prevent premature pavement distress and enhance road performance, it is imperative to provide an adequate characterization of asphalt. For this purpose, the current re...

SMA is a gap graded mix composed of high concentration coarse aggregate that held together in thick asphalt film by matrix mineral filler and stabilizers. Since natural aggregates have become expensive, hence Reclaimed Asphalt Pavement (RAP) can be reused pavement construction to reduce the environmental hazardous due disposal problems. RAP contains used aggregates, it highly prone fatigue, the...

The integration of circular economy principles in the design road pavements raises problem obtaining high-performance asphalt mixtures for reduction waste and environmental pollution compared to traditional solutions. In this study, base binder layers were prepared by using reclaimed pavement construction demolition as coarse aggregates, while jet grouting fly ash served fillers. A leaching tes...

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...

Pavement recycling is an appropriate technology for constructing and restoring road pavement structures due to the limited supply high cost of materials. This study aims improve recycled mix's performance by replacing fine aggregate in mix with Buton Granular Asphalt (BGA). The percentage material (Reclaimed Pavement/RAP) mixture was 20% 30% weight total mixture. BGA added 3%, 6%, 9% each RAP v...

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...
