Nanomaterials exhibit novel properties and profound attributes as an additive in asphalt binder modification. However, the application of nano-silica binders mixture modification is still limited, further research required. Along these lines, this work, with a content from 2% to 8% increment was utilized modifying bitumen type C320, which considered most conventional used Western Australia road...

Rutting (i.e., depressions along the wheel path) is a distress exhibited by flexible asphalt pavements at high in-service temperatures negatively affecting ride comfort and safety. In this regard, fine mortar bitumen filler sand) plays key role in rutting potential of mixtures. Given background, manuscript presents small-scale laboratory experimentation aimed assessing rutting-related performan...

Abstract The performance of asphalt concrete pavements (ACP) is greatly related to the rate rutting. Stone dust mostly used as a filler in ACP. Bagasse ash being cementitious nature, and costless waste can also be filler. overall aim select suitable for better pavements. effectiveness locally available bagasse examined terms its effect on job mix formula, stability, rutting depth, rise temperat...

Attacks on humans by wild boar (Sus scrofa) are occasionally reported in rural areas of Turkey. While fatalities are rare, individuals may sustain significant soft tissue trauma. Lower extremity lacerations of up to 10 cm in length and 4 cm deep were seen in the 3 cases reviewed. Injuries to the upper abdomen and chest occurred in one case. Attacks frequently occur in forested areas covered by ...

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...

pavement design using mechanistic-empirical methods is often carried out based on the some assumptions for pavement layer's properties (thickness, elastic modulus, poisson's ratio and ….), loading properties(axial weight, tire coordinates, number of repetitions and …) and also the failure mechanism for different materials. fulfillment of these assumptions for evolution of pavement performance d...

This study explores the effects of polyphosphoric acid (PPA) on rheological performance styrene butadiene (SBS) and crumb rubber (CR) modified asphalt binders at high temperatures. Four PPA concentrations were selected: 0.4%, 0.8%, 1.2%, 1.6% by weight virgin asphalt, one SBS binder with 5% was used as a reference binder. Laboratory tests performed to simulate short-term long-term aging. Temper...

Recently, nanomaterials have been widely used to improve the properties of asphalt binders due their unique properties. This research aims evaluate performance nano-modified with two different types nanomaterials, which are Nano-Silica (NS) and Nano-Clay (NC). Each them was added a 60/70 penetration grade bitumen at concentrations ranging from 1% 4% by binder weight using high shear mixer speed...
