in this study, different contents of nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen tomodify the physical, mechanical and rheological properties of warm mix asphalt (wma). wma iscontaining 2 wt.% of sasobit (mixture of long-chain hydrocarbons). various quality control tests have beencarried out to characterize the modified bitumen and wma. the rheological investigations show...

This paper presents a PDF-matched modification to Stone’s measure of predictability. The modified measure of predictability is a measure of non-gaussianity too. It is an extent of signal predictability by two different prediction terms. One prediction term is based on a normal gaussian PDF assumption for signal. In contrast, the other one is based on a unit variance supergaussian PDF assumption...

We study the breaking of integrability by a finite density dilute impurities, specifically emerging diffusive transport. Provided distance between impurities (localized perturbations) is large, one would expect scattering rates to be additive, and therefore, resistivity proportional number (the so-called Matthiessen's rule). show that this is, in general, not case. If transport anomalous origin...

Recently, nanomaterials have been widely used to improve the properties of asphalt binders due their unique properties. This research aims evaluate performance nano-modified with two different types nanomaterials, which are Nano-Silica (NS) and Nano-Clay (NC). Each them was added a 60/70 penetration grade bitumen at concentrations ranging from 1% 4% by binder weight using high shear mixer speed...

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...

This paper is aimed at selectivity investigation of gas sensors, based on chemically modified nanocrystalline tin dioxide in the detection of CO and ammonia mixtures in air. Sol-gel prepared tin dioxide was modified by palladium and ruthenium oxides clusters via an impregnation technique. Sensing behavior to CO, NH3 and their mixtures in air was studied by in situ resistance measurements. Using...

Fuzzy rule bases can be regarded as mixtures of experts, and hoosting techniques can be applied to learn them from data. In particular, provided that adequate reasonin: methods are used, fuzzy models are extended additivc models. thus backfitting can be applied to them. We propose to use an implementation of backfitting that uses a genetic algorithm for fitting submodels to residuals and we als...

Novel syntactic foams made of starch and ceramic hollow micro-spheres were developed. Foams of four different micro-sphere size groups were manufactured with either preor post-mould gelatinisation process. Compressive failure behaviour and mechanical properties were evaluated. Not much difference in failure behaviour or in mechanical properties between the two processes (preand post-mould gel) ...
