Which type of paper is used for FC5?

The correct answer is that silicone coated non-stick paper is used for FC5 because this type of paper offers properties that are crucial for handling and utilizing materials in asphalt testing and applications. Silicone coated paper provides a non-stick surface that prevents asphalt mixes and other sticky substances from adhering to it. This is particularly important during testing and transport, as it ensures that the sample can be easily removed without compromising the integrity of the material.

In contrast, regular paper is not suitable due to its absorbent nature, which could interfere with asphalt samples by absorbing oils or liquids. Wax paper, while moisture resistant to some extent, typically does not provide the necessary non-stick properties required for asphalt samples. Plastic coated paper may offer some resistance but lacks the specific non-stick qualities of silicone, making it less ideal for this type of application.
