Despite the fact that significant funds are granted to construction and repair of the roads, most of the roads do not comply with the quality requirements of European Union. However, it is not always the fault of the road construction companies. Another reasons for poor road quality is increasing traffic intensity and truck load, as well as rather bad weather conditions in our region.The major reason for destruction of asphalt surface is caused by its low resistance to water and cold, mainly impacted by bad adhesiveness of bitumen with other substances of asphalt (sand, dolomite or granite). As a result, small holes in asphalt are filled with water, destructing the bonds between bitumen and minerals. During cold seasons, when temperature fluctuations are significant, it creates wide cracks on the surface of asphalt.
Adhesiveness of bitumen and mineral materials is improved by using adhesive additives. It also decreases asphalt preparation time and temperature, increasing asphalt construction season and decreasing consumption of scarce energy resources.
Our bitumen additive „AMDOR-9", „AMDOR-10”, „AMDOR-TC-1” has been tested in Russian State laboratories and various private laboratories of road construction companies. All the tests confirmed unique characteristics of „AMDOR-9", „AMDOR-10”, „AMDOR-TC-1” and positive impact on the quality of the asphalt. Testing approved that adding of „AMDOR-9", „AMDOR-10”, „AMDOR-TC-1” to bitumen at concentration rate 0.5% significantly increases qualitative features of bitumen:
- Increases elasticity of bitumen;
- Decreases aging of bitumen after heating;
- Decreases asphalt water throughput rate;
- Increases asphalt resistance to temperature fluctuations;
- Bitumen, directly in oil refineries;
- Bitumen, in asphalt production plants;
- On mineral materials (sand, dolomite, granite) before or after application with bitumen;
- Mobile asphalt production units.
„AMDOR-9", „AMDOR-10” is to heated to liquid state (usually 40-80°С ) and, by using dosage equipment, added to bitumen boilers or directly to asphalt production equipment. Adhesive additive decreases asphalt heating temperature from 10 to 20°С. This has significant impact on asphalt features as minimizes overheating of bitumen, resulting in loss of bitumen characteristics.
Economic efficiency from use of „AMDOR-9", „AMDOR-10”, „AMDOR-TC-1” gives the following results – from USD 10.000 to USD 15.000 economy on construction of 1 kilometer long and 7 meter wide road pavement!
