A runway pavement during its useful life is subject to a series of deteriorations because repeated load cycles and environmental conditions. One the most common formation rutting (surface depression in wheel path) on surface. Rutting negatively affects aircraft performance landings will behave even worse precipitation or with existence fluid contaminations This paper aims develop model for calc...

The intensive construction of all categories roads and the very demanding maintenance pavement structures existing due to ever-increasing traffic loads confronts us with a lack resources also an increase in cost for constituent materials asphalt mixtures. On other hand, there is another problem: large amounts waste material form bio-ash, which obtained by burning wood biomass production thermal...

In ground-based harvesting, machine traffic can cause soil physical disturbances including excessive compaction, the displacement of surface and topsoil, rutting. These impacts indirectly hamper seedling survival tree growth because reduced permeability root growth. However, extent disturbance in mechanized row thinning by harvester forwarder systems South Korea is unclear. Therefore, our objec...

An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste material...

A 25-year-old man was bitten in the neck by an aggressive camel, causing three small puncture wounds. The left carotid pulse of the patient was weakly palpated. Angiography showed irregular dissection of the distal part of the left common carotid artery. Neck exploration confirmed the findings. An interposition autogenous saphenous vein graft was performed successfully. The patient was discharg...

The effect of modification asphalt concrete mixtures different grain sizes with “Ric-Polycell” (Ukraine) and “Duroflex®-SMA” thermoplastic polymers (Germany), which were added directly to the mixer during their preparation, on properties was studied. It is confirmed that it more expedient use stone mastic concretes a larger size mineral crushed grains high-traffic roads, as they are rutting-res...

Based on the Novachip ultra-thin layer project in expressway, material characteristics, mixture design and road performance of asphalt are introduced. The application effect was observed. results show that has no obvious improving smoothness original surface. rutting, a good anti-skid performance.
