WebIn warmer regions, bitumen with lower penetration grades are preferred. 29. Bitumen with lower penetration grades are used in colder regions. 30. Good bitumen should have temperature susceptibility 31. Affinity and adhesion are required for good bitumen 32. Bitumen Grade 80/100 indicates, penetration value is less than 80. 33. Web10 Jan 2024 · A steel ball is placed upon the bitumen sample and the liquid medium is heated at a rate of 5 o C per minute. Temperature is noted when the softened bitumen touches the metal plate which is at a specified distance below. Generally, higher softening point indicates lower temperature susceptibility and is preferred in hot climates. WebIn EN 12591, a second set of characteristics enables to specify bitumen. Penetration index, dynamic viscosity at 60 degrees, thrust breaking point which define the susceptibility of bitumen under low temperature condition. And cinematic viscosity at … smart business insurance australia
