WebThe specific gravity of bitumen is defined as the ratio of mass of given volume of bitumen of known content to the mass of equal volume of water at 27 C. The specific gravity can be measured using either pycnometer or preparing a cube specimen of bitumen in semi solid or solid state. The specific gravity of bitumen varies from 0.97 to 1.02. WebOther quality parameters of bitumen are flash point, viscosity, brittleness temperature, density, cohesive and adhesive properties. Penetration of bituminous material is the … Web120-150. Softest Bitumen Grade 200-300. The penetration grading system is 100 years old bitumen grading method. In India, before 2006, the most widely used grade of bitumen was 60 to 70. For the construction of low volume roads and to perform spraying, penetration value from 80 to 100 was used. trez yeild trust us cdn $
