Investigation of stress and heat strain in asphalt workers
Heat stress is one of the harmful factors in workplaces. Asphalt workers are exposed to thermal stress due to the open environment and process. The aim of this study was to assess the heat stress and strain in asphalt workers. This study was conducted on 29 employees of asphalt workstation. The heat stress was measured based on Wet-Bulb Globe Temperature (WBGT). Also, physiological parameters s...
متن کاملDevelopment of An Artificial Neural Network Model for Asphalt Pavement Deterioration Using LTPP Data
Deterioration models are important and essential part of any Pavement Management System (PMS). These models are used to predict future pavement situation based on existence condition, parameters causing deterioration and implications of various maintenance and rehabilitation policies on pavement. The majority of these models are based on roughness which is one of the most important indices in p...
متن کاملReduction of Urban Heat Island Effect through Harvest of Heat Energy from Asphalt Pavements
Asphalt pavement surfaces contribute significantly to the urban heat island effect. Their relatively high temperature, caused by absorption of solar energy, results in emission of heat to the surrounding air, leading to a rise in its temperature, deterioration of its quality, and an increase in energy consumption of the surrounding buildings. The proposed concept is that the heat from the pavem...
متن کاملDETERIORATION OF PITTING CORROSION OF 316 STAINLESS STEEL BY SENSITIZATION HEAT TREATMENT
In this research pitting Corrosion of a sensitized 316 stainless steel was investigated employing potentiodynamic, potentiostatic techniques. Sensitization process was carried out on as-received alloy by submitting the specimen in electric furnace set at 650°Cfor five hours and then the specimen was quenched 25°C water. Potentiodynamic polarization of as received and sensitized specimens in 1M ...
متن کاملInvestigation of Low Heat Accumulation Asphalt Mixture and Its Impact on Urban Heat Environment
This study is focused on investigating the effectiveness of low heat accumulation asphalt mixture and its impact on the urban heat environment. Infrared radiation experiments showed that the temperature of the asphalt mixture decreased with the increase in far-infrared radiant material. The results also revealed that, compared to asphalt with 0% far-infrared radiant content, the asphalt materia...
