The effect of asphaltene on thermal properties of bitumen

摘要: Abstract Chemical composition and any variation of four main components bitumen (asphaltene, saturated, naphthene aromatic polar aromatic) have effective impact on its properties especially, thermal properties. In other words, in order to asphalt pavements with reasonable temperature susceptibility stability, first all it is essential know the effect these Therefore, this research effects were investigated was found that penetration index (PI) viscosity number (PVN) increased increasing asphaltene content. Thermal behavior an oxidizing environment also studied using thermogravimetric analysis (TGA) technique. The results showed content decreases improves resistance samples decomposition.
