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 ...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
estimation the fatigue number of stone mastic asphalt mixtures modified with nano sio2 and nano tio2
asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...
The increasing rate of traffic every day requires the roads to be made more stable. In order improve low and high temperature properties bituminous mixtures forming coating layer flexible pavements, binder in mixture is often modified with various polymers. most commonly used polymer modification styrene-butadiene-styrene (SBS). However, SBS, which very successful improving mechanical mixtures,...
