Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration...

The effectiveness of weight ratio mineral filler to effective bitumen in the fatigue performance asphalt mixture with integral granules was investigated based on experiments mastic (mixture and passed through sieve grade 200). included a dynamic shear rheometer, elastic recovery, linear amplitude sweep tests other mixture, such as indirect tensile resilient modulus test for assessing medium tem...

This study aimed to determine how various concentrations of warm mix asphalt (WMA) additives can affect the rheological and physical characteristics cement. Bitumen was modified by chemical additive PAWMA® with an addition ratio (0.2, 0.4, 0.6), while organic additives, Sasobit® Kaowax®, were added at (2, 4, 6%) weight bitumen. hardness, softness, temperature susceptibility, viscosity, elastic ...

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.
