How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The car-oriented approach of cities in Iran has caused to decrease in the share of active travel modes in recent years. In contrast, cycling as an active travel mode can play a crucial role in intra-city movements and reduce motorized travel modes' disadvantages. On the other hand, active travel modes are more practical for short distances and are...

Hydroplaning speed can be affected by pavement texture depth, thickness of water film, tire pressure and tread depth. In this study, to understand the influence of pavement texture on the hydroplaning speed, a new lab-scale apparatus has been designed and manufactured. The lack of proportion between linear movement of vehicle shaft and the wheel ro...
Article
The existence of any liquid on the pavement surface causes a decrease in skid resistance. Heavy rain storm or improper surface grading leave a water film on the pavement surface. By increasing water film and vehicle velocity, there is a moment in which hydroplaning phenomenon can occur and causes the vehicle linear speed to become disproportionate...
Article
Skid resistance of asphalt pavements is one of the most important road criteria for users' safety. In a rainy condition the skid resistance is largely compromised and when the road surface is flooded, vehicles can experience hydroplaning at a certain critical speed. Tires under hydroplaning conditions become separated from the pavement surface and...
Article
Effects of two of the most important factors influencing permanent deformation of styrene-butadiene-styrene (SBS)-modified and unmodified asphalt-frequency and temperature as well as their interactive effects-are studied using dynamic creep test. The authors used a sophisticated experimental design method known as central composite design (CCD) tha...
Article
There are several approaches for improving adhesion and moisture sensitivity in asphalt mixtures, one of which is to coat the aggregate surface with a suitable agent to change the predominant electrical charges at the surface and reduce the surface energy of the aggregate. In this study, the effects of using Zycosoil as an antistripping additive on...
Article
Effects of different parameters including aggregate type, asphalt mix design and construction, traffic and environmental conditions on moisture sensitivity of asphalt mixtures have been investigated by a large number of researchers. But, only a few researchers have reported combined effects of these parameters. The aim of the current study is to ev...

The number of inversion and smog days of Tehran seems to increase every year and this is an alarming sign for the city and governmental authorities. Some strategies have been implemented but the number of dangerous or polluted days have not dropped during recent years. The first step of pollutants emission management is prediction of pollutants amo...
