THE RHEOLOGICAL PROPERTY OF SHANJIASI AND KELAMAYI HEAVY OIL ASPHALT. SELECTED PAPERS ON HIGHWAY AND TRANSPORTATION RESEARCH 1988

The rheological properties of Shanjiasi and Kelamayi No. 9 District heavy oil asphalt were compared with those of Shengli asphalt over a 60-160 degrees Centrigrade temperature range. The results showed that these two kinds of asphalt had improved properties which were equivalent to or close to those of the Japanese asphalt. Testing the rheological properties with a rheometer at different temperatures and shear strain rates showed that when the temperature is greater than 60 degrees Centigrade, the asphalt approached a newtonian liquid, and evaluating asphaltic properties with a viscosity-temperature curve and a BTDC (bitumen test data chart) was very useful. Wax had an adverse effect on the working performance of the asphalt by decreasing its viscosity at high temperatures and decreasing its penetration at low temperatures. Shanjiasi asphalt could comply with all the requirements for heavily trafficked roads except for the penetration index, which was slightly too low. If the penetration index could be raised, the temperature susceptibility and ageing resistance would be imposed. Generally speaking, Kelamayi asphalt had good properties except for its specific gravity, which was less than 1.0, and for its wax content, which was slightly too high. (TRRL)
