 Civil Engineering Research Journal- Juniper Publishers   Abstract Major urban arterial streets in large cities are experienced a serious traffic accident problem. This study attempts to investigate the possible effect of traffic volumes and arterial geometry on traffic accidents, where arterials in Amman city were selected as a case study. Based on a set of predefined criteria, eight major urban arterial segments were selected. The number of traffic accidents and traffic volumes were obtained from the Public Security Directorate and Greater Amman Municipality, respectively, for the period from 2015 to 2017. Other geometric and operational data were obtained through field survey. The total sample sizes for daily and hourly accidents consisted of 1407 and 33768 observations, respectively. Negative Binomial regression model was used to investigate the impact of urban arterial traffic volumes and geometric design variables such as, segment length, number of horizontal curves, lan...

 Civil Engineering Research Journal- Juniper Publishers   Abstract The article provides an analysis of the operating conditions of port facilities in heavy hydrometeorological conditions on the coast of Sakhalin Island to establish durability characteristics for the development of design life models. Typical types of concrete destruction in the zone of variable level are considered. The directions of research in the field of forecasting the durability of concrete and reinforced concrete structures for seaport facilities on actual durability characteristics are outlined. Keywords: Concrete; Durability; Sea port facilities Go to Introduction The modern design concept of construction facilities according to operational characteristics implies a variable approach to the assignment of requirements to structures and materials for structures, which should guarantee the predicted service life while maintaining the economic feasibility of the service life [1]. The principle of this des...

 Civil Engineering Research Journal- Juniper Publishers   Abstract Fatigue cracking is very critical among all types of distresses in pavements once the fatigue crack start in pavement it led to fast pavement deterioration and thus reduced the life of pavement and quality of riding on pavement. Thus, to control such distress it is necessary to understand the mechanics behind such crack initiation and propagation and to find the fracture parameters to choose best mixture to resist the failure. There are various methods to understand the fracture properties of the bituminous concrete (BC) mix. This paper describes the semi-circular bending test for BC mix, which was designed to be very effective, and user friendly. This method is adopted because it simulates the field conditions and its availability. Semi-circular samples of forty-eight were prepared out of which half was made of unmodified bitumen and the rest were made of plastic modified bitumen. These all samples were then t...
