Reclaimed asphalt pavement (RAP) arises from the demolition of road layers. The Optimal Recycling Asphalt Pavements Project concerns cold recycling 100 % RAP without binder addition in base and subbase layers low-traffic roads. In this context, a test program was performed with Rhine region materials to evaluate impact mastic coating untreated RAP. A source reclaimed asphalts 4.4 bitumen is tes...

Traditional LCA of central plant hot recycling shows that, the higher RAP added, the less energy consumed. This conclusion is mainly based on the calculation of reduced raw material. However, when the content of Reclaimed asphalt pavement mixture (RAP) reaches some level, it is needed to take measures such as using additive or improved construction method for maintain the performance of asphalt...

The current focus of research attention on reclaimed asphalt pavement (RAP) utilization is expanding the applications RAP. This study aims to analyze road performance recycled permeable mixtures (RPAMs), which represents a novel direction for utilizing Firstly, Marshall design method was used carry out material composition RPAM with varying RAP contents (10%, 20%, and 30%). Subsequently, differ...

The durability of asphalt mixtures against floodwater immersion can serve as a reference to anticipate potential road damage. Moreover, Reclaimed Asphalt Pavement (RAP) materials have been discovered substitute for aggregate in pavement due their environmental friendliness and cost-effectiveness. Therefore, this research aimed assess the produced using RAP 1, 2, 4, 8 days. process involved Ston...

Each of pavements’ life cycle phases such as material extraction, transportation, construction, operation, rehabilitation, and end-of-life emits greenhouse gases. Such emissions can be influenced by climate change via changes in the rates of pavement deterioration and thus intensity and frequency of maintenance and rehabilitation. However, climate change has not been given full considerations i...

This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused in fresh construction. Some of the advantages associated with pavement recycling are (i) less user delay (ii) conservation of energy (iii) preservation of...

Stone mastic asphalt (SMA) is a gap graded mix which categorised by more quantity of coarse aggregate, high content and fibre. Due to stone on contact presences filler content, it acts as stiff matrix reduces the rutting due heavy traffic load. This research presents study fatigue performance RAP replaced SMA mixes using VG 30 binder along with elastomer modifier results were compared conventio...

In China, the construction of asphalt pavement has a significant impact on the environment, and energy use and greenhouse gas (GHG) emissions from asphalt pavement construction have been receiving increasing attention in recent years. At present, there is no universal criterion for the evaluation of GHG emissions in asphalt pavement construction. This paper proposes to define the system boundar...
