In 2008, together with the State Enterprise “BeldorNII” introduced the technology unit dedusting gravel carriageway roads by the “sandwich”. Stabilization and dedusting gravel of the type “Sandwich”, provides economic benefit to 50% of the value on the roads with low traffic. This type of coverage is identical to asphalt concrete pavement. In this regard, improved road characteristics: it does not produce dust and does not require its profiling, which reduces maintenance costs.
Since this technology has established itself with the best hand, in 2010 he published a series of regulations that will produce this kind of work without the support of the State Enterprise “BerdorNII.”
