Low Temperature Bitumens

A reduction of critical temperatures in the production of mineral-asphalt mixtures is an increased demand on the part of investors. Low-temperature bitumens are produced by an addition of organic components, chemically interacting to decrease critical temperatures. The most commonly additions are: synthetic paraffin and low-molecular-weight ester. The melting point of both components is 99°C. Their 3-4% (m/m) addition to a bitumen causes a decrease in its viscosity after melting and, consequently, a reduction in critical temperatures ranging from 18°C to 54°C.
