Comprehensive Description of Bitumen 70/100
Bitumen penetration grade 70/100 is a versatile paving-grade bitumen widely used in road construction and hot-mix asphalt production. Contractors choose this grade for its consistent performance, which results from its thermoplastic properties. It softens at high temperatures and hardens at lower ones, making it ideal for various climates and applications. With a penetration range of 70 to 100 mm/10 at 25°C, determined through penetration and softening point tests, this bitumen ensures durability and reliability.
Softening Point and Penetration Properties
Gold Bitumen produces pure petroleum-grade bitumen 70/100 using advanced vacuum bottom processing and hot air treatment. This process removes hydrocarbons and enhances product quality. Grade 70/100 offers a penetration range of 70 to 100 desi-millimeters and a softening point between 43 and 51°C. Its thermoplastic nature allows it to soften when heated and harden upon cooling. Furthermore, its high viscosity compared to other grades makes it an excellent choice for demanding construction applications.
Primary Uses of Bitumen 70/100
Engineers rely on Grade 70/100 for road construction and repair projects. Moreover, it serves as a key material in producing durable hot-mix asphalt for bases and wearing courses. Specifically, this grade delivers exceptional results in challenging environments, including tropical regions.
Applications of Penetration Grade 70/100
Penetration-grade Grade 70/100 is known for its superior durability and performance. For example, it is frequently used in asphalt pavements where long-lasting results are essential. Additionally, this grade is integral to the production of hot-mix asphalt for base layers and wearing courses, meeting the highest standards for construction projects.
