An effective neutralizer of emissions of H₂S and SO₂, formed during manufacture, transport and making of the pavements based on sulfur-bitumen concretes, is developed in REC «Nanotechnology». Existing neutralizers of emission are with effect of “masking” the odor of H₂S and SO₂. Because of this, the toxic gases can not be effectively eliminated. The proposed neutralizer chemically binds H₂S and SO₂. Thus, the emission of sulfur dioxide and hydrogen sulfide is reduces in 45...50 and 13 times, respectively.
Application of the developed modifier allows using sulfur as a structuring component in road construction during the manufacture of hot sulfur-bitumen concretes. This provides a reduction in the cost of construction (per 1 km of the roadway) by reducing the amount of expensive binder – bitumen – in asphalt concrete, and also partially solves the problem of environmental disposal dumps of sulfur produced during the extraction of oil and gas.

Nano-sized organomineral modifier for asphalt binders allows to reduce the amount of bitumen (30-40%) in the production of asphalt and improve the durability of asphalt pavement: to reduce the amount of 25-50% of rutting in the operation. Modifier reduces emission of hydrogen sulfide (10 times or more) and sulfur dioxide (more than 45 times) during manufacture, transport and laying sulfur-bitumen concretes.
