Performance Evaluation of Polymer Modified Bitumen in Flexible Pavement
The growth in various types of industries together with population growth has resulted in enormous increase in production of various types of waste materials world over creating a problem of its disposal in eco-friendly way. To deal with the problem, study on use of plastic waste as partial replacement to bitumen in flexible pavement is considered in the present work. The work consists of an ex...
متن کاملComparative Study of Eva and Waste Polymer Modified Bitumen
Polymer-modified bitumen is used to combat different pavement distresses and to increase the life span of pavement. Unmodified bitumen cannot perform better with the range extreme minimum and maximum pavement temperatures. The polymers commonly used to modify the bitumen are ethylene vinyl acetate (EVA) styrene butadiene styrene (SBS). The aim this study to compare the performance of EVA modifi...
متن کاملMicrostructure evaluation of polymer-modified bitumen by image analysis using two-dimensional fast Fourier transform
Aiming to quantitatively evaluate the microstructure of polymer-modified bitumen (PMB) for roads, this paper employs the two-dimensional fast Fourier transform (2DFFT) to process the microscopic and numerical images of four PMBs. The related derivative parameters, including the characteristic frequency and wavelength, are computed from the 2D-FFT power spectrum. The results show that the absenc...
متن کاملRetrospective exposure assessment for carcinogenic agents in bitumen waterproofing industry in Finland and denmark.
OBJECTIVES The purpose of the study was (i) to identify the carcinogenic agents that may cause confounding when studying the exposure-response relationship between bitumen fume exposure and cancer among roofing membrane-manufacturing workers and roofers and (ii) to assess exposures to the identified carcinogens and bitumen fume in roofing membrane manufacturing and roofing in Finland and Denmar...
