Influence of microcrystalline cellulose on the sdvigoustoychivost and water resistance of stone mastic asphalt

During tests influence of the stabilizing additive of microcrystalline cellulose (MKTs) en a sdvigoustoychivost and water resistance of the stone mastic asphalt (SMA) is studied. Maintaining additive increases coefficient of internal friction of a mineral component of asphalt concrete. MKTs additive has the stable relations caused by hemosorbtsionny interaction on limit of the section of the phases «bitumen-the surface of fibre» that increases ShchMA water resistance. It is established that MKTs additive introduction significantly improves properties of asphalt concrete in comparison with import dobavkoytopcel, and also with traditional asphalt concrete of type A.
