Difference between Asphalt and Tar correct answers Asphalt is soluble in petroleum, tar is not. Asphalt has bitumens, tar has low bitumens Two Different Distillation Process to Produce Asphalt correct answers 1. Fractional Distillation: Crude oil is heated, lighter oils vaporize and are drawn off, leaving behind asphalt cement 2. Destructive Distillation: crude oil heated under pressure to higher temperatures than fractional distillation Penetration test correct answers -Test hardness...
