Laboratory scale mechanical performances on six plant produced mixtures; three semi-dense surface courses and dense binder modified with engineered crumb rubber (ECR) using the dry process are presented. The two types of mixtures investigated fulfilled for most part, requirements Swiss and/or US standards regarding volumetric properties, water sensitivity rutting. In advanced testing where no e...

Abstract This research article investigates the influence of oxidized polyethylene (PE) polymer on rheological and performance properties SBS modified bitumen at an optimum dose 0.5 % by weight. To evaluate impact PE different testing such as indirect tensile strength resilient modulus was conducted blended bituminous concrete mixes rheology determined using dynamic shear rheometer. It conclude...

This paper summarises the results of radon diffusion coefficient measurements in 360 common waterproof materials available throughout Europe. The materials were grouped into 26 categories according to their chemical composition. It was found that the diffusion coefficients of materials used for protecting houses against radon vary within eight orders from 10(-15) to 10(-8) m(2) s(-1). The lowes...

Spreading sodium chloride salt is one of the most effective operations to tackle ice formation on surface a road pavement during cold seasons, thus ensuring safer driving conditions. However, in addition negative environmental impact, solution could influence properties and durability asphalt mixtures. Based these premises, this laboratory study aims characterize mechanical different mixtures e...

Reclaimed asphalt pavement (RAP) is gained from road reconstructions; however, its usage less optimised in Hungary and neighbouring regions, since on the project level proportion of RAP mixes only 10-15%. This than recommended other EU countries. The higher provides economic environmental advantages, decreasing need for new materials, transport cost, carbon footprint. composition resultant bitu...
