South Gobi road of 240-km flexible pavement was constructed from UKHAA KHUDAG to GASHUUN SUKHAIT in South Gobi, Mongolia in 2011. However, due to the heavy traffic and severe weather condition, early distresses have occurred from a length of 100-km flexible pavements in South Gobi road after one year service life. In order to enhance crack and rutting resistances and to improve paving quality control in South Gobi road, polymer modifier is selected to reduce rutting at high temperature and cracking at low temperature and warm-mix asphalt (WMA) additive is selected to reduce the mixing and compacting temperatures and provide better compaction on the road and the ability to haul paving mix for longer distances. This paper adopted comprehensive asphalt tests to evaluate physical and rheological characteristics, and crack potential at low temperature for use in a South Gobi road. Laboratory tests were performed on asphalt binder with a polymer modifier and warm-mix asphalt additive by conducting the following tests: softening test, ductility test, SuperpaveTMtest and cold bending test. These test results of asphalt binder with SBS polymer modifier and warm-mix asphalt additive were significantly more positive than those of typical asphalt binder. On the basis of test results, it can be concluded that the asphalt binder with SBS polymer modifier and WMA additive is stronger and less susceptible to rutting and crack than typical asphalt binder used in South Gobi.

Acceleration of a vehicle is composed of three components: longitudinal, lateral, and vertical acceleration. Longitudinal and lateral accelerations have been frequently considered as components for investigating driving behaviour, with the aim of improving road safety. But in particular situations during the motion of the vehicle, also vertical acceleration is relevant. In this paper, the authors want to demonstrate that vertical acceleration is also a relevant parameter to be considered in terms of road safety. The authors focus on the difference registered by considering only lateral and longitudinal acceleration and by considering also vertical acceleration in the analysis of driving behaviour through real tests on the road. All the parameters were registered through a global positioning system (GPS) device and a tri-axial accelerometer, which allow the geo-referenced kinematic parameters of the vehicle to be detected. For this purpose, over 110 tests covering about 600 kilometers were completed. All the experimental surveys were conducted in a good weather condition, under dry road pavement conditions, on weekdays, during day time and out-of-peak hours, in order to have no influence from the traffic flow. Each path was repeatedly run by the driver in order to collect the instantaneous speed and acceleration along the pattern. During the tests, about 40,000 instantaneous values of vehicle position have been registered. The survey interested a segment of the Italian National road n.107 (S.S. 107), in Southern Italy. The authors found that by considering vertical together with longitudinal and lateral accelerations, a higher number of unsafe driving conditions can be identified. More specifically, the proposed methodology allows 20% extra of dangerous driving conditions to be registered. For this reason, the authors retain that also vertical acceleration should be considered in the definition of the safety domain, because it determines the intensity of the exchange forces between the tires and road pavement, and in some cases, it leads to a loss of friction. Definitively, the authors retain that vertical acceleration is not only useful as indicator of comfort on board, but it has an important role also in terms of road safety.

This article presents the information received from documents available in the Police Head- Quarters, Operation Department, Traffic Directorate, Naxal, Kathmandu and Metropolitan Traffic Police Division, Kathmandu along with some journals and websites covering five years from 2069 to 2074. The main aim of carrying out this research was to shed light on the road traffic accidents of Kathmandu valley. The data have been presented through document analysis and analyzed here using both quantitative and qualitative techniques. The major findings include that Road Traffic Accidents are the outcomes of many factors ranging from the negligence of the driver to the weather condition and the condition of road. Despite the dense presence of government and its bodies, the study showed that maximum number of road traffic accidents occur in Kathmandu valley. Youngsters riding bikes and driving cars involved in accident are found maximum in number. Because of the immediate rescue and hospitalization, the number of deaths in Kathmandu valley was found to be decreasing in comparison to the other parts of Nepal.Journal of Health Promotion Vol.6 2008, p.37-44

The need to address the problem of thermal comfort inside a car cabin is becoming more significant for the automobile industry especially as recent developments in vehicle styling entail an increase in the glazed surfaces of the car, in particular for sky-roof models. The extended glazed surfaces produce an increase in radiative thermal loads on the area involved and so greater attention is being given to the enhancement and upgrading of the heating, ventilation, and air-conditioning system capacity, and efforts are being made to find solutions to the problem of thermal comfort inside the cabin. This paper is a first experimental study which focuses on assessing the performance of four different types of special laminated sky-roof (with a low-emissivity internal surface). A performance comparison between special and traditional sky-roofs has been carried out in a field test (on the road) in summer conditions. The main results show that the special sky-roofs allow the temperature inside the car cabin to be reduced.

The most adverse weather condition for road safety happens when there is water, snow, or ice on the road surface because their presence highly decreases friction. Therefore, it is essential to drain or repel them quickly. If the water drops are repelled from the surface or the ice/snow formation is avoided with the application of superhydrophobic coatings, roads become safer. In order to functionalize the asphalt mixtures used in road pavements, nano/micromaterials, such as Polytetrafluoroethylene (PTFE), TiO2, and SiO2, among others have been applied by spraying coating. The mixes are usually characterized by the water contact angle, and the surface roughness is typically assessed by optical and electron analysis. This research work aims to present a brief overview of superhydrophobic asphalt mixtures.
