IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …

Effect of Thickness in Electroluminescence Spectra on 2-5 Dialoxy-PPV (ROPPV) Films
Abstract: The optical properties and electroluminescence (EL) of ROPPV (2-5-dialoxy-PPV) films of various thicknesses have been studied. The thickness of ROPPV layer on glass slide was measured by Fizeau fringes interferometric technique which varied from 200 to 400 nm. The absorption spectra show that the absorption occurred only in ultraviolet region. Thick films show only one peak at 310 nm, whereas by decreasing the thickness, the peaks are obtained at lower …

Performance of Integral Bridge by Addition of Cross Girders
Abstract: The bridges without expansion joints are Integral Abutment bridges (IAB’s). In conventional bridges, the bearings are generally corroded due to water seepage through joints which are avoided in IAB’s. However there will be stresses developed due to thermal induced movements of the bridge which is to be taken into account. In this paper, finite element analysis is carried out using STAAD ProV8i on a typical model of IAB. Here various …
