APPLICATION OF ZYCOSOIL IN BITUMINOUS MIX

Rapid increase of urban population in India with rapid rise in industrialization needs high demand of vehicles.Road sectors are very important for the growth of economy, employments and empowerment of a country.India's road network with nearly 55 lakh Km road length is second largest road network in the world.About 98% roads are flexible in nature and rest 2% are rigid pavements.Approximately 40% roads are unpaved of total road lengths.The natural bitumen shows failure and serious problems during rainy seasons.Because of increasing traffic load in term of number of axles and high tyre pressure due to heavy vehicles the traffic related pavement distresses are found in the pavement.Stripping occurred because of moisture damage is considered as one of important pavement distress in bituminous pavement since 1990s.Moisture damage causes the stripping of pavement layer aggregate which is to be considered as a serious problem these days.Moisture damage is progressive loss of functionality of the materials because of that there is the loss of adhesion between bitumen binder and the aggregates, Zycosoil as an anti-stripping agent is used to provide the better adhesion bond between bitumen binder and the aggregates in the presence of water.The treatment and strengthening of bitumen is required to keep the pavement surface serviceable.Zycosoil, a Nano material recently used as an additive to strengthen the pavement surface and to improve the properties like penetration, ductility and moisture damage of pavement.
