The apparent diffusion coefficients of tris(2,2'-bipyridyl)ruthenium ([Ru(bpy(3))](2+)) are estimated in silica-nanochannels which are assembled inside columnar alumina pores in an anodic alumina membrane, and are modified with alkylsilanes such as trimethylchlorosilane (C1), butyldimethylchlorosilane (C4), and dodecyldimethylchlorosilane (C12). The estimation is performed by observing the lag-...

This review paper shows several sections of bitumen, asphalt mixtures, polymers, and waste plastic in pavement engineering. The reviews evaluates the influence using polymer improving rheological engineering properties modified binder mixtures. Evaluation design stone mastic mixtures are reviewed. Reports studies had investigated advantages importance bitumen modification; however, they yet sho...

The use of modifiers for bituminous binders has become common practice to enhance the performances asphalt materials. As a result, binder becomes more complex, with various phase morphologies. Conventional testing methods may not always be suitable. example, European standardisation committee is looking at different ways characterise Polymer modified Bitumen. RILEM Technical Committee 272-PIM ‘...

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 ...
