Abstract

Optimal concentration of bitumen is considered in the bitumen - clinker cement ratio, and basic properties of bitumen are studied both the hardness under (00C, 250C) and the melting point. The introduction mechanism of complex modifier – clinker cement and surface active material – lignosulphonate is detected. According to the received experimental results, the most effective method of mix preparation is chosen and by the usage of this method, with the introduction of complex modifier the above mentioned properties are increasing respectively 58,8; 41,6 and 17 percents.
