The paper presents the classification of the main causal aspects of the occurrence of catastrophes of large-span bridge structures, given with elements of the analysis of actual examples of the destruction of structures of various types. Also are described the innovative developments applicable in the field.

Keywords: fatigue failure, bridge, large-span bridge, failure of structures, destruction of bridge structures, accident in construction, resonance, wear, aerodynamics of bridge structures, stiffness beam, bolted joint

The article contains an analysis of the shortcomings of the majority of existing stabilizing additives for shale-mastic asphalt-concrete mixtures. In the paper, the results of the use as a stabilizing additive for blast-mastic asphalt-concrete mixtures of a composition consisting of cellulose fibers treated with organic binder and mineral fiber are considered.

Keywords: stabilizing additive, crushed-mastic asphalt concrete, cellulose fiber, mineral fiber, bituminous binder, road surface

The physicochemical properties of bitumen samples of road oil improved have been studied. It is established that the samples submitted for testing meet the regulatory requirements practically throughout the entire range of tests, except for the values ​​determined after heating the binder in a thin film according to the procedure of EN 12607-2 (EN 12607-1), which, apparently, indicates the insufficient stability of these bitumens to thermal and oxidative aging. The influence of the adhesive additive on the intensity of bitumen wetting of the surface of mineral materials was studied

Keywords: bitumen petroleum road improved, resistance to thermal and oxidative aging, regulatory requirements

The article presents the results of experimental studies of changes in the physico-mechanical and operational performance, polymer-dispersion-reinforced asphalt mixtures depending on the temperature of the mineral material and the time of mixing the components in the preparation of the material in the coating plant

Keywords: asphalt concrete, stone mastic asphalt concrete mixture, the wear layer, grain structure, sieve, fraction, track, toughness, shear resistance, roughness.

The article presents the main provisions of the work garmonizatsii such European standards as TL Asphalt-StB 07 and the Finnish standards on asphalt PANKry with the requirements of the RF regulatory framework and given the developed compositions of asphalt mixtures, SMA-11 and their physico-mechanical characteristics.

Keywords: asphalt concrete, stone mastic asphalt concrete mixture, the wear layer, grain structure, sieve, fraction, track, toughness, shear resistance, roughness

The influence of the amount of the addition асфальтогранулята on the properties of asphalt mixes and asphalt. Also considered is the impact of technology of filing асфальтогранулята on physical-mechanical properties of asphalt mixes.

Keywords: old asphalt, asphalt, astringent, physico-mechanical properties, homogeneity.
