The article provides information on the physical and mechanical properties of polymer-bitumen compositions obtained by modifying road bitumen BND 50/70 with elastomers SKEPT-60 SKN-26 determination composites. composite samples various concentrations (2.5, 3.0, 5.0%, 6.5 7.0%) were determined: needle depth, softening, brittleness flash point, stretching adhesion. It was determined that characte...

In this study, the corrosion resistance of a bituminous coating reinforced with different ratios of nanoclay pigment was studied. To make nanocomposite coatings, 2, 3, and 4 wt.% of clay (Cloisite Na+) were incorporated into water emulsified bitumen. The coatings were applied to steel 37. Optical microscopy and X-ray diffraction (XRD) were used to characterize the nanocomposite structure. In or...

The ability to anticipate the effects of interaction between waste rubber particles from end-of-life tires and bitumen can encourage use rubberized bitumen, a material with proven environmental benefits, in civil engineering applications. In this study, predictive model viscosity is presented for purpose. A machine learning-based approach (Multi-Gene Genetic Programming—MGGP) more traditional m...

Aging peculiarities of paving bitumen, which was obtained by different ways, have been studied. Oxidized and residual bitumen produced from oils Ukrainian deposits were used the changes in main characteristics after 5 10 h aging a thin film at temperature 436 K determined processes occurred during Using infrared spectroscopy, structural composition binder analyzed.

To restore the performance of old bitumen which has been stiff and hard to become maltenes, it is necessary add a rejuvenator makes will soften increase. This paper presents results physical property tests aged incorporating rejuvenators. The conducted were Penetration, Softening Point (SP), Viscosity (VIS), in form oil-based namely ceca base was added with variation 0.3%, 0.5%, 0.7%, 1.0% from...

Softening and dropping point determination are established analytical tests that provide quality control for petrochemical products such as bitumen (asphalt). However, to be accurate, manual/semi-automated quality tests prescribed in ASTM standards must be performed in a standardized fashion. Unfortunately, manual processing bears inherent process risks that affect repeatability, which in turn ...
