SOFTENING POINT OF ASPHALT AND PITCH
SOFTENING POINT OF ASPHALT AND PITCHGENERALAsphalt and pitch do not go through a solid-liquid phase change when heated, and therefore do not have true melting points. As the temperature is raised, they gradually soften or become less viscous. For this reason, the determination of the softening point ...
