Opis:
Sidewalks play a very important role in the dynamism maintenance as well as the development of cities especially historic cities. To ensure the maintaining service quality of sidewalks, the first step is to prevent distress occurrence, thereafter repair the distress that occurred in the sidewalks. In historic cities, the lack of suitable sidewalks for walking led to the gradual elimination of pedestrians. Yazd is a historic city recorded as a world heritage site by UNESCO, which attracts many tourists from all over the world every year. Therefore, preserving the quality of sidewalks in this city is of great importance. In this research, the SCI method was used to investigate the condition of the sidewalks in the studied area. This method is similar to the pavement condition index (PCI) method. The results showed that the condition of sidewalks in the studied area is in the range of 55-70, which is relative.

Opis:
Skip resistance of asphalt is an important parameter that can influence the safety of drivers on roads. Although there is a linear relationship between slipping on road surfaces and accidents, the impacts of pollutants for decreasing friction of roads is clear to researchers. Moisture and temperature influence friction and safety. In this research in SMA samples, three different gradations with the maximum nominal sizes of 19, 12.5 and 9.5, based on international standards were used. For polluting the surface, five materials that are found on roads were used, including fine-grained soil, sand, oil, soot and rubber powder. To measure the skip resistance, the British pendulum tester was used and for analysing macro-texture, the sand patch method was used. The results of this research showed that by increasing the maximum nominal size of aggregates, the depth of macro-texture in surfaces are grown and this is due to the decrease of fine aggregates in larger gradations. Because of the higher flexibility of pure bitumen, the applied compression pressure on rigid aggregates can cause indentations in the substrate and result in declining the roughness height of aggregates in the mixed surface. This leads to declining the hysteresis part of friction by increasing temperature.

Opis:
Today, the increasing development of urbanization and climate change and its resulting issues, including the occurrence of urban floods, is one of the important issues facing city managers. One of these problems that seriously affect lives today is the occurrence of floods and the inundation of urban thoroughfares. Among the problems of floods in urban areas are the disruption of the urban transportation system, reduced transportation safety, inundation of thoroughfares, and consequently, the poor appearance of urban roads. One of the successful strategies in controlling urban runoff is the use of porous pavements in urban thoroughfares. The two capabilities of permeability and evaporation of a porous pavement lead to reduced runoff and a resultant lack of occurrence of inundation of thoroughfares; therefore, accurate measurement of these two parameters is of special importance. This study aims to introduce two devices for measuring the permeability and evaporation of porous asphalt with an innovative method that can measure the permeability and evaporation of asphalt and porous concrete with appropriate accuracy.
