Bitumen 30/40

Bitumen 30/40 Overview

Bitumen 30/40 is a standard penetration grade bitumen produced from vacuum residue (short residue) feedstock. This bitumen exhibits thermoplastic properties, which means it softens at higher temperatures and hardens at lower ones. The temperature-stiffness relationship of bitumen 30/40 largely depends on the type of crude oil and its refining process. This bitumen grade is semi-hard, making it ideal for road construction and repair, Additionally, it serves as a key material in asphalt pavement production, Due to its high viscosity and superior performance, it is one of the most commonly used bitumen grades.

Uses of Bitumen 30/40

Bitumen 30/40 works effectively for road construction and repairs. It is also essential for producing hot mix asphalt for bases and wearing courses. This grade ensures that asphalt pavements remain durable and resilient under heavy traffic, Additionally, it finds widespread use in maintaining and enhancing road infrastructure, The material provides long-lasting durability and stability, making it suitable for various construction and roadwork applications.

Softening Point and Penetration of Bitumen 30/40

Jey Pasargad supplies pure petroleum-grade bitumen 30/40. It is produced through vacuum distillation and passing hot air through the bitumen, The bitumen comes from the residual material left after cracking and hydrocarbon removal from crude oil, This grade has a penetration range of 30 to 40 desi-millimeters and a softening point between 55°C and 63°C, Its thermoplastic nature allows it to soften when heated and harden when cooled, much like synthetic resin materials. Bitumen 30/40 has a stronger viscosity compared to other grades, making it highly effective for use in road construction and other applications requiring high durability.

Application of Bitumen Penetration Grade 30/40

Bitumen 30/40 proves ideal for road construction and repair, especially for asphalt pavements. It offers superior properties that ensure long-lasting performance. This grade is used to produce hot mix asphalt for both bases and wearing courses. Its strong bonding properties guarantee that road surfaces remain stable and durable. Consequently, it plays a significant role in infrastructure projects that demand reliable and resilient road materials.

Specification and Analysis of Bitumen 30/40

The specification and analysis of Bitumen 30/40 are as follows:

– Specific gravity @ 25°C: ASTM D70 shows that the specific gravity ranges between 1.01 and 1.06 kg/cm³. This range ensures the bitumen performs well in road construction.
– Penetration @ 25°C: ASTM D5 reveals a penetration range between 30 and 40 mm/10. This value determines the bitumen’s suitability for various asphalt mixes.
– Softening point: ASTM D36 reports a softening point between 55°C and 63°C. This ensures that the bitumen maintains flexibility across various weather conditions.
– Ductility @ 25°C: ASTM D113 shows that the bitumen’s ductility measures at least 100 cm. This result indicates that the bitumen can stretch without breaking, ensuring durability and resistance to cracking.
– Loss on heating: ASTM D6 reveals that the loss on heating does not exceed 0.2%. This shows that the bitumen resists volatilization at high temperatures, maintaining stability.
– Drop in penetration after heating: ASTM D5-D6 indicates that the drop in penetration after heating should not exceed 20%. This result shows the bitumen’s stability after exposure to high temperatures during the mixing process.
– Flash point: ASTM D92 states that the flash point is a minimum of 250°C. This ensures the material remains safe during handling and application.
– Solubility in CS2: ASTM D4 reports a solubility in carbon disulfide (CS2) of at least 99.5%. This confirms the bitumen’s high purity and quality.
– Spot test: AASHTO 102 shows that the spot test result is negative. This indicates the bitumen remains free from impurities that could impact its performance.

Overall, these specifications highlight Bitumen 30/40’s high quality and suitability for road construction and asphalt production.
