The degradation of bituminous materials as a result ageing has significant effect on asphalt pavement performance. In this study, one porous (PA) section and stone mastic (SMA) were designed constructed in 2014 exposed to the actual environmental condition. To study change pavement’s mechanical properties, cores collected from both test sections annually. stiffness modulus was determined via cy...

The study aims at investigating diffusion behaviors between virgin asphalt and recycled mastic (RAM) an atomistic scale. Firstly, a mutual model of asphalt–RAM considering the actual mass ratio filler to binder (F/A) condition was developed by molecular dynamic (MD)simulation. Secondly, indexes relative concentration (RC), radial distribution function (RDF) mean square displacement (MSD) were u...

BACKGROUND Gum of Chios mastic (Pistacia lentiscus var. chia) is a natural antimicrobial agent that has found extensive use in pharmaceutical products and as a nutritional supplement. The molecular mechanisms of its anti-inflammatory activity, however, are not clear. In this work, the potential role of antioxidant activity of Chios mastic gum has been evaluated. METHODS Scavenging of superoxi...

This study compared the long-term noise reduction performance through field measurements using different asphalt pavement methods. The main variables were type of methods, including porous, Stone Mastic Asphalt (SMA), and thin-layer. Noise data over last 11 years was analyzed. porous pavements continued to decrease due pores filling time that maintenance is necessary three post-construction. Si...

Nowadays, the most common ways to dispose of acid tars and paper production waste are burial or incineration, but it is ecologically economically expedient use such in building materials. A new variant filler aggregate—wastepaper sludge ash (paper waste) a chemical activator for aggregates—acid tar (oil-refining industry proposed. Elemental mineralogical compositions wastepaper comparison with ...
