Bitumen burns while comprising a small percentage of all types of burns are troublesome. They affect persons engaged in gainful employment which the burns then curtail, as well as requiring special attention because the substance adheres to the skin and is therefore difficult to remove. Ninety-two consecutive patients with such burns who were admitted as in-patients over a 10-year period (1985-...
After closure of a waste disposal cell in a repository for radioactive waste, resaturation is likely to cause the release of soluble species contained in cement and bituminous matrices, such as ionic species (nitrates, sulfates, calcium and alkaline ions, etc.), organic matter (mainly organic acids), or gases (from steel containers and reinforced concrete structures as well as from radiolysis w...
In the presence of various catalysts (TiCl4, AlCl3, H2SO4), process obtaining a coumarone-indene-carbazole resin (CICR), which is produced from liquid products coal coking, and its subsequent use for bitumen modification was investigated. The influence catalyst type on yield modifying properties CICR (change in thermoplastic adhesive after adding obtained resins to them) studied. effect amount ...
due to performance grade )pg) zonation of different parts in iran and poor properties of 60/70 penetration grade bitumens for pavement applications, suitable polymer modifed bitumen was produced. to fulfll this purpose, different pmbs samples were produced using 60/70 penetration grade bitumen and various percentages of vb (20 and 25%), with different percentages of sbs calpre...
Initial processing of Athabasca oil sands obtained from the water-based extraction process yields stable water-in-bitumen emulsions.When the bitumen is diluted with naphtha to reduce its viscosity and density, partial separation can be obtained with a suitable demulsifier. However, a “rag layer” forms between the clean oil and free water layers. The partially oil-wet kaolinite in clay solids ca...
Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits. The mechanism of WMA is to use some additives or technologies to reduce the viscosity of bitumen and to modify the rheological behavior of bituminous binders, and thus improve the workability of the mixture at lower temperature. In this study a paraffin wax based addit...
In this data article experimental data on the compressive strength, and the durability of styrene and bitumen modified sulfur concrete against acidic water and ignition are presented. The percent of the sulfur cement and the gradation of the aggregates used are according to the ACI 548.2R-93 and ASTM 3515 respectively. For the styrene modified sulfur concrete different percentages of styrene ar...
Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...
Increasing environmental awareness has led to a great research effort towards the formulation of increasingly sustainable pavements, mainly by developing bituminous mixtures incorporating waste materials. Furthermore, some materials have been proved be useful for enhancing performance road bitumen and products, so their use is potential solution ensuring environmental, economic, also technical ...
