In general, land use and layout of streets can have a significant impact on the behavior of drivers and pedestrians. In particular, streetscape has often been overlooked that recognizing the role of streetscape on street accident in urban areas is important. The aim of this research is to investigate the influence of streetscape and land use on urb...

Accidents have various economic, social, cultural, environmental, health and human dimensions. This research examines urban accidents such as pedestrians, cyclists, motorcycles and cars, as well as the severity of each of them, taking into account the factors affecting accidents, such as the type of limitations caused by space and place, population...

There has been an ever-climbing trend toward environmental concerns in addition to road technical issues, resulting in the testing of new high-quality pavements. First, due to the presence of acidic contaminants in surface runoffs in developed areas rooted in acid rainfall, researchers have discovered that these polluted runoffs can pollute groundw...

First, porous asphalt (PA) pavement possesses a lower strength and lifetime compared to typical dense-grade asphalt mixtures due to its large empty space structure. Second, PA pavements' fatigue life and durability are affected significantly by climate factors; the two most critical factors being aging conditions and moisture actions. Third, becaus...

In this article, the results of a laboratory study performed on the PMSS mixture containing ceramic waste powder (CWP) as a filler substitute compared to asphalt prepared with mineral aggregate powder (MAP) were presented. The tests performed were; wet cohesion test, wet-track abrasion test, loaded wheel test-displacement and loaded wheel test-sand...

The aim of the current research was to develop models to predict the severity of accidents on rural roads in Tehran province, Iran. In this regard, using accident data from 2017 to 2020, the machine learning algorithms, including multiple logistic regression, multilayer perceptron neural network (MLPNN), and radial basis function neural network (RB...

Porous asphalt (PA) mixture is a hot mix asphalt with an open gradation that has a high amount of air void in its structure. Although this high volume of empty space in PA has several road safety and environmental benefits, it causes some performance drawbacks like reducing PA mixes’ resistance against rutting and cracking and increasing sensitivit...

Nowadays, it is necessary to understand the factors affecting accidents, especially on rural roads. In this study, in order to determine the most effective factor in the occurrence of accidents, analysis and modeling of effective factors on rural roads of Guilan province in 1392 to 1397 have been conducted. First, frequency analysis was used to eva...

In this research, the fracture and fatigue resistance of short and long-term aged hot and warm mix (HMA and WMA) stone matrix asphalt (SMA) mixtures containing 0%, 30%, 40%, and 50% RAP materials were investigated using semi-circular bending (SCB) and four-point beam fatigue (4 PB) test methods. It is further noted that three temperatures (− 20 °C,...

Due to several types of deterioration, such as rutting, fatigue cracking, and thermal cracking, that occur in the structure of pavements, researchers have developed solutions, including constructing pavements with enough resistance against permanent deformation, such as stone matrix asphalt (SMA) mixtures, and delaying the pavements’ deteriorations...

Due to the environmentally associated issues regarding the construction or rehabilitation of asphalt pavements with merely virgin materials, researchers have proposed the re-utilization of the reclaimed asphalt pavement (RAP) materials. However, their adoption in asphalt pavements is detrimental to the fatigue performance of asphalt pavements. For...

The increasing number of vehicles on rural roads as a result of population growth has led to one of the most important problems of the transportation system, namely traffic accidents, which affects the economic and social situations of the people. Guilan province is one of the most beautiful tourist areas in northern Iran and many business and leis...

The high number of fatalities on rural road accidents is recognized as one of the biggest safety concerns in developing countries. Modeling the severity of pedestrian accidents according to the effective parameters provides the possibility of predicting the occurrence or non-occurrence of accidents. In addition, this model can be used to examine th...

The purpose of this study was to develop models to predict the severity of pedestrian accidents on rural roads of Guilan, Iran. Therefore, the probability of occurrence of any type of accidents was measured using the accident data from March 2014 to March 2019. Eleven independent variables affecting the severity of pedestrian accidents as well as s...

Performing comprehensive research on the functional behavior of asphalt pavements under the influence of various environmental and structural parameters can better assist the engineers in the design and maintenance of asphalt pavements. Using a solution that can reduce the cost and time of assessment is very important. Using artificial neural netwo...

For representing the first two stages of creep phenomenon, both Burger’s and generalized creep models are suitable, however, these models are not enough to describe the third stage. Therefore, for predicting the visco-elasto-plastic glasphalt behavior, a visco-plastic string is added to these two models in series. This study seeks to compare the mo...

On the basis of previous studies, it has been demonstrated that glass is capable of improving the behavioral characteristics of asphalt mixtures. The purpose of the present study is to assess the effect of nanotechnology zycosoil on rutting resistance and stiffness modulus of glasphalt mixtures through laboratory experiment. For this purpose asphal...

Several researches have been done for evaluating the mechanical and mechanical properties of glasphalt mixtures. Stripping and moisture damage are the main causes of glasphalt deterioration. Moisture damage in hot mix asphalt (HMA) occurs due to a loss of adhesion and/or cohesion, resulting in the reduced strength or stiffness of the HMA and the de...

This paper focuses on the experimental investigation on temperature sensitivity and visco-elastoplastic behaviour of glasphalt. Classic Burgers creep model could only describe the viscoelastic behaviour of materials before the third creep-phase, so a viscoplastic string is added in series with classic Burgers model in order to predict the visco-ela...

Analogous to most visco-elastoplastic materials, the creep curve of asphalt mixture can be generally divided into three-stages: decelerated creep, equi-velocity creep and accelerated creep. The Burgers model which can exhibit linear visco-elastic behavior is suitable to describe the first two stages of creep process and is not enough to represent t...

In this research the linear visco-elastic behaviour of glasphalt mixtures is investigated.

Stiffness Modulus (SM) is an important factor in predicting the resistance of pavements to dynamic loading. Stiffness modulus is defined as the rate of stress -strain variation in axial loading, which shows the behaviour of an asphalt mixture under loading conditions. The behaviour of asphalt mixtures is sensitive to both temperature and duration o...
