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...

Class C fly ash is a coal combustion product normally produced from lignite or subbituminous coal obtained as a result of the power generation process. In recent years, efforts were taken to incorporate self-cementing fly ash into full-depth reclaimed (FDR) asphalt pavements to improve the structural capacity of asphalt pavement base layers. In this study, an existing asphalt pavement in County...

The use of reclaimed asphalt pavement (RAP) is increasing importance due to fast-growing amounts demolished road materials. However, can contain relevant pollutants such as carcinogenic polycyclic aromatic hydrocarbons (PAHs) and toxic metals. In order improve the mechanical properties recycled asphalt, rejuvenators are used reduce stiffness aged binder. These in turn may potentially mobilise l...

Nowadays, the use of reclaimed asphalt pavements (RAP) is often combined with Warm Mix Asphalt (WMA) technologies with several benefits in terms of environment, cost and mechanical performance. Concerns still exist related to in-service and aging characteristics of warm recycled mixtures since WMA technologies have been developed over the last decade and hence long term performance data are not...

Abstract Recycling pavements is beneficial on various levels, since using reclaimed asphalt (RA) has a positive effect the economy and environmental protection at same time. Removed old pavement no longer considered as waste material, which to be landfilled, but useful material for further applications. Leading reduction of need virgin materials preserve planet. At start, RA was used constructi...

In the last decade, innovative technologies with regard to improved energy and material efficiency of asphalt pavement construction have been implemented by road industries. Two technologies are currently advocated: warm mix asphalt technologies and the increased use of reclaimed asphalt pavement. Unfortunately, these technologies were evaluated only by their technical and economic benefits and...
