The specific weight of a substance refers to the ratio of its weight to its volume, while density represents the ratio of its mass to its volume. Density remains constant regardless of the gravitational acceleration, whereas the specific weight is influenced by Earth's gravity.
Knowing the density of bitumen is crucial for calculating the weight of bitumen stored in tanks and tankers at road construction sites, where volume measurements are used. The measurement of bitumen density follows the ASTM D70 standard and is based on Archimedes' principle. It serves as an interface between the mass and volume of the substance.
Common methods for determining the specific weight (density) of bitumen include using a nickel crucible and a pycnometer.
In calculations related to bitumen, the term "amount" refers to its weight, despite practical measurements being based on volume. Since bitumen is heated for use and its volume changes in storage, it is essential to account for its coefficient of thermal expansion. Therefore, the specific weight of bitumen is always considered at a specific temperature and in accordance with the designated test method.
The test method based on the ASTM D70 standard is as follows:
Bitumen Density Test Objective:
The objective of this test is to determine the specific weight and density of special bitumens and semi-solid bituminous materials using the pycnometer method.
Bitumen Density Test Description:
- Start by filling a 600 ml beaker with distilled water and place it in a water bath, ensuring that the top of the beaker is above the water level. Dry the pycnometer and weigh it with a precision of 1 mg, recording the weight.
- Remove the beaker from the water bath and fill the pycnometer with distilled water, loosely placing the lid on top. Submerge the pycnometer inside the beaker and close the beaker's lid. Allow the pycnometer to fill with water, allowing any excess water to escape through the hole on top.
- Take out the pycnometer filled with water from the beaker, dry it, and weigh it, recording the weight. Empty the pycnometer and dry it thoroughly.
- Fill three-quarters of the pycnometer volume with the bitumen sample. Allow the sample to cool, then weigh the pycnometer with the sample and record the weight.
- Place the pycnometer containing the sample back inside the beaker and fill the remaining volume with distilled water. Remove the pycnometer from the beaker, dry it, and weigh it using a scale.
- Use the standard formula specified in this test method to calculate the density of the bitumen sample based on the recorded weights.
By following these steps and performing the necessary calculations, the density of the bitumen sample can be determined in accordance with the ASTM D70 standard.
Density of bitumen 60/70
Bitumen 60/70 is a commonly used grade of bitumen in road construction and paving applications. The density of bitumen 60/70 refers to its mass per unit volume.
The density of bitumen 60/70 typically ranges from around 1,000 to 1,050 kilograms per cubic meter (kg/m³) or 1 to 1.05 grams per cubic centimeter (g/cm³). However, it's important to note that the density may vary slightly depending on factors such as temperature and specific manufacturing processes.
The density of bitumen is an important parameter as it affects various aspects of its performance, such as its flow characteristics, durability, and resistance to deformation. It is crucial to consider the density of bitumen during the design and construction of road pavements, as it helps determine the appropriate quantity of bitumen required for specific applications.
Determining the density of bitumen 60/70 is typically done through laboratory testing methods such as the pycnometer method, where the mass and volume of the bitumen sample are measured to calculate its density.
Overall, the density of bitumen 60/70 is an important property to consider when specifying and using this grade of bitumen in road construction projects.
Density of bitumen 80/100
Bitumen 80/100 is another commonly used grade of bitumen in road construction and paving applications. The density of bitumen 80/100 refers to its mass per unit volume.
The density of bitumen 80/100 typically ranges from around 1,000 to 1,050 kilograms per cubic meter (kg/m³) or 1 to 1.05 grams per cubic centimeter (g/cm³). However, it's important to note that the density may vary slightly depending on factors such as temperature and specific manufacturing processes.
Similar to other grades of bitumen, the density of bitumen 80/100 is an important factor in determining its flow characteristics, durability, and resistance to deformation. Understanding the density of bitumen 80/100 helps in estimating the required quantity of bitumen for road paving projects and ensures proper mix design.
Laboratory testing methods, such as the pycnometer method, can be used to determine the density of bitumen 80/100. This involves measuring the mass and volume of the bitumen sample and calculating its density using the obtained data.
In summary, the density of bitumen 80/100 is a crucial property to consider when using this grade of bitumen in road construction. It helps in ensuring the appropriate quantity and performance of the bitumen for specific applications.
