This study has included a modulation of the rheological properties of asphalt by a catalyst chemical treatment with polycarbonate, and the microwave technique was used at a power of (360) watt at time intervals. Furtherm...

The research was aimed to use the residual asphaltic materials taken from northern refinery in the preparation of activated carbon by oxidation with V O5 in the presence of a stream of air for 3hrs at 350°C temp, .The r...

Chemical modification of asphalt had been used to modify the rheological properties by treatment with sulphur at different experimental conditions. The modification achieved by using application of microwaves (microwave ...

Abstract This study aims to develop a performance grade (PG) zoning map for asphalt pavements along the Kabul–Salang Highway in Afghanistan, considering local climatic conditions and traffic factors, to support optimiz...

This study investigated the potential of polyvinylpyrrolidone-grafted graphene (PGR) for secondary reinforcement of SBS and microwave-activated crumb rubber (ACR) modified asphalt, aiming to clarify the underlying mechan...

Improving road transportation accessibility is essential for enhancing local social and economic activity in a country. One way to maintain the accessibility of the road network and ensure that users feel safe and comfor...

As one of composition materials (asphalt, aggregate, mineral powder) for hydraulic asphalt concrete, the mineral powder has a messy process of manufacture. Comparatively, the cement is easily processed and available for ...

Abstract The research aimed to study the effect of Diols on modification of an asphaltic materials which could be used as a binder for paving material obtained from Qaiyarah asphalt. 0.5-5 wt.% of Diols (ethylene glycol ...

There is a growing need for the production of certain types of asphaltic materials having good rheological properties compared with the unmodified asphaltic materials, thus many experiments were performed to prepare a mo...

Reactive oxygen species (ROS, ·OH, ·OOH, and O₂) are ubiquitous in urban environments and may significantly accelerate asphalt pavement aging, yet their interactions with asphalt components remain poorly understood. ...

The performance of asphalt mixtures modified with 7% and 10% waste tire and solid natural rubber is assessed in this study, along with the effects of replacing fine aggregate with these materials. According to binder tes...

The asphalt industry faces growing challenges from stringent greenhouse gas (GHG) reduction mandates and diminishing high-quality virgin material reserves. This review paper positions upcycling as the engineered transfor...

Paleohistological studies of vertebrates are based on the analysis and interpretation of bone microstructure of petrographic thin sections. These sections are mainly performed following standard techniques; however, the ...

Urban sprawl, the uncoordinated and spatially dispersed expansion of urban areas into surrounding rural lands, poses significant challenges to sustainable development, resulting in the loss of agricultural and forest lan...

Abstract Semi-flexible pavement (SFP) combines the flexible properties of asphalt with the rigidity of a cementitious slurry, providing improved structural and durability performance. However, the reliance on ordinary Po...
