Potentiometric investigation on {H2O+NaNO3+PEG1500} mixtures were made at T=308.15K, using electrochemical cells with two ion-selective electrodes, (Na+ glass) as the cation ion-selective electrode against (NO3- solvent-polymer PVC) as the anion ion-selective electrode. The mean ionic activity coefficients of NaNO3 were measu...

Palm oil clinker (POC) is a non-biodegradable palm mill by-product typically discarded in dumpsites. This study analyzed the performance of POC powder (POCF) as bitumen modifier terms conventional and engineering properties asphalt mixture. For study, base 60/70 penetration grade was utilized different POCF dosages (0, 2, 4, 6, 8% by weight bitumen) were added. The effectively modified with the...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

Vigorous and continued efforts by researchers engineers have contributed towards maintaining environmental sustainability through the utilization of waste materials in civil engineering applications as an alternative to natural sources. In this study, granite aggregates asphaltic mixes were replaced electric arc furnace (EAF) steel slag with different proportions identify best combination terms...

Stone mastic asphalt (SMA) has become widely used in the field of pavement engineering. Using specific additives SMA is necessary due to climate change and load condition variations. Thus, it essential utilise a modern mixture with high capacity survive traffic loads. The current study aims use combination waste polyethene terephthalate (PET) Nano-silica (NS) as newly developed hybrid additive ...
