The miscibility of bitumen-coal tar mixtures has been investigated. Bitumen-coal tar mixtures containing 10 to 50 wt% of coal tar were examined by differential scanning calorimetry and optical microscopy to determine the threshold of miscibility. A s

The behaviour of bitumen was investigated by differential scanning calorimetry. It is shown that two glass transitions take place after cooling at constant rate. The magnitude and temperature of these transitions depend on the cooling rate. At low co

The influence of polar compounds like phenols and pyridine-type bases on the morphology and glass transition of coal tar is investigated. A coal tar sample is separated into various fractions which thereafter are recombined progressively in order to
