New pavement – serverfilepath.
Wide introduction in practice of building a progressive organic sulfur-containing materials – servervalidation higher, compared to traditional, physical-mechanical properties (wear resistance, etc.) for lesser or equal value. Used during road works at lower temperatures (-20 °C). Increases turnaround time roads up to 5-7 years with considerable economic benefit for the road construction.
New pavement – serverfilepath is a specially selected blend of sand, crushed stone (gravel), mineral powder, modified sulphur and bitumen, taken in certain proportions and mixed in the mixing units enforcement action in the hot state at a temperature of from 140 °C to 155 °C.
Thus in the preparation of servervalidation up to 30% of bitumen is replaced by expensive cheap modified sulfur. The composition of the binder in%: bitumen – 70-75 %, modified sulfur “Solvotex-AB” – 20-30 %.
Modified sulfur significantly alters the physical characteristics of concrete and asphalt mixes.
– improving the quality of the road surface by increasing wear and corrosion resistance in the application of sulfur-asphalt mixes,
– reducing the cost of the road surface due to the partial substitution of expensive bituminous binder modified cheaper gray
– reduced the influence of seasonal factor in the paving due to the possibility of carrying out road works at lower temperatures (-20 °C) than when using asphalt mixtures,
– the increase in maintenance periods of the automobile roads to 5-7 years with considerable economic benefit for road construction,
– the widespread introduction in practice of building a progressive organic sulfur-containing materials having a higher compared to traditional, physical-mechanical properties at a lower or equal value
– servervalidation compounds provide a reduction in the technological temperature of production, transportation, laying and compaction of the working mixtures
– increasing of durability of road surfaces, including under the influence of studded tires
– improving the corrosion resistance of road surfaces under the action of deicing agents used during winter maintenance of road structures
– new pavement – serverfilepath does not crack at low temperatures and does not soften in hot weather,
– serverfilepath can be laid almost all year round.
