ANTISTRIPPING PROPERTIES OF ASPHALT MODIFIED WITH TALL OIL PITCH

Loss of adhesion of the asphalt binder to the mineral aggregate causes a weakening or destruction of asphalt pavement. One way to cope with this situation is to treat asphalt mixes with either conventional or new and innovative antistripping materials such as Tall Oil Pitch (TOP). Four different asphalts originating from two Western Canadian crude oils were modified with TOP and mixed with aggregates from three different sources. These mixes were tested by using Retained Marshall Stability Test, Boiling test and modified Lottman procedures. The TOP antistripping properties were evaluated against lime and commercial alkylamine antistripping agent, using the same mixes. The experimental results demonstrated that the TOP possesses strong antistripping properties, comparable to conventional antistripping additives, when used for treatment of stripping susceptible asphalts and aggregates.
