The effective adhesive additive, liquid with the increased thermal stability, "Karbozolin by joint stock company" which provides strong coupling of bitumen with mineral material (5 points or 96 - 100% ) is developed. Thanks to it, the water resistance of asphalt concrete considerably increases and formation of a yamochnost on a paving is prevented.
The additive "Karbozolin of joint stock company" also allows: - To slow down asphalt concrete aging process; - To perform a roadwork from early spring to late fall; - To save up to 10% of bitumen; - To reduce temperature of preparation and laying of asphalt concrete mixes by 10 - 15 °C; - To improve quality of surface treatments and patching.
At much smaller cost the additive by efficiency and heat stability prevails over domestic and world analogs for this period.
For release of an adhesive additive "Karbozolin the joint stock company" got permission of the Ministry of Health of Ukraine and is registered standardly - technical documentation.
The necessary maintenance of additives in bitumen makes 0,2 - 0,3% .
It is skilled - production lots "Karbozolin of joint stock company" were used at construction and repair of roads in Ukraine throughout fall of 2015 and received positive comments.
Besides, at profile branch institute of Ukravtodor agency (GP "Gosdor of Scientific Research Institute") researches of influence of an adhesive additive "Karbozolin of joint stock company" on improvement of a stseplivaniye of bitumen with mineral material are conducted.
According to the conclusion, introduction of 0,3% "Karbozolina of joint stock company" in bitumen increases its coupling with crushed stone from 2 points to 5 points and glass from 35% to nearly 100% . At the same time the additive does not lose the activity at warming up in bitumen up to the technological temperatures.
The additive is entered into the bitumen heated to the working temperature (120 - 170 °C) and mixes up with it within 30 - 40 minutes.
Period of storage of the modified bitumens without loss of activity till 5 days at a working temperature.
Warranty period of storage "Karbozolina of joint stock company" makes not less than one year
