bituminous emulsion insulators are types of bituminous emulsions groups composed of different grades of bitumen emulsified in water by bentonite and emulsifiers at 80-90oc. these emulsions are water resistant after drying andtheir physical and mechanical properties are superior in comparison to bitumen properties. iranian climate, because of variety and extreme variations in temperature imposes...

The cold in-place recycling (CIPR) is a process where the existing bituminous pavement is recycled without application of heat. In CIPR process the scarified material from the existing pavement is crushed to the required gradation and binder in cold form (emulsion or cutback or foamed bitumen) is added. Externally acquired Reclaimed Bituminous Pavement (RBP) or fresh aggregates are also added d...

Environmental and health aspects of road materials have been discussed for a long time, mostly regarding bitumen and bitumen fumes. However, just a few studies on other types of road materials have been reported. In this doctoral study, two types of materials, asphalt release agents and bituminous sealants, were investigated with regard to chemical characterization and emission profiles. Beside...

Poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. To improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. The main objective of this study is to explore the influence of...

In the asphalt industry, bituminous emulsions are widely used in road pavement operations and building/construction processes such as cold mix waterproofing processes, respectively. A very important fact to keep mind is that not all types of bitumen suitable for realization emulsions. This largely due variation their chemical nature different cracking carried out on during fractional distillati...

In this article the study is done for adhesion of aggregates coming from various granite quarries Ukraine with bituminous binder, namely bitumen emulsion – application in surface dressing technology road pavements treatment. there are used Ukrainian and European testing methods determination “bitumen aggregate” system. According to method, was determined residual binder chips after boiling dist...

At the low Landau filling factor termination of the fractional quantum Hall effect series, two-dimensional electron systems exhibit an insulating phase that is understood as a form of pinned Wigner solid. Here we use microwave spectroscopy to probe the transition to the insulator for a wide quantum well sample that can support single-layer or bilayer states depending on its overall carrier dens...
