Introduction . Currently, increasing the durability of road asphalt concrete pavements is one urgent issues, solution which provides a significant economic effect achieved by turnaround time, as well overall service life highways. Asphalt with prolonged wetting due to weakening structural bonds can be destroyed crumbling mineral grains, leads increased wear pavement and formation potholes. Wate...

Exercise training causes increased oxidative stress. Pistacia Atlantica Extract (Mastic) is known to have a protective effect against oxidative stress and inflammation. We examined the effects of exercise training with and without Pistacia Atlantica extract administration on antioxidant markers in vistar rats. Twenty-eight Vistar female rats (six to eight weeks old, 150-200 g weight) allocate...

The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica. In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders. Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed aspha...

The evaluation of environmental impacts for low-noise roads is a challenging topic in life cycle assessment (LCA) due to noise reduction considerations. This paper presents hybrid modifications conventional LCA, using acoustical pavement characterization data from the close proximity (CPX) test, and models emission, propagation exposure incorporate inventories road traffic noise. Furthermore, b...

Rutting is one of the most common distresses in early damage to asphalt pavements. It can raise risk ride safety issues, accelerate pavement deterioration, and increase maintenance costs. To investigate factors that affect rutting resistance mixtures, internal (such as aggregate gradation, content, layer thickness), external (including temperature traffic loading), human compaction degree) were...
