Potential of using organic additive produced with kaolin-clay in bituminous roadways

Roadway performance can be improved through utilizing modified bitumens and/or bituminous mixtures within the structure. Regarding this view, Kaolin-containing-Organic Additive Material (K-c-OAM) has been synthesized chemically in study. K-c-OAM is a new additive material obtained laboratory conditions with reaction of kaolin, kind clay, and ethylene glycol. 50/70 penetration grade neat bitumen by concentrations ranging from 1 % to 4 %. The effects on both mixture properties have investigated experiments including rotational viscosity, penetration, softening point, ductility, Nicholson stripping Marshall tests. Stability values found increased at level varying between 6.4 9.5 bitumens. In areas where hot climate not dominant, roadway pavements said provide better according findings.
