Marshall Paper Disc

High-Quality Marshall Paper Discs for Asphalt Specimen Preparation

The CANTROL Marshall Paper Disc is a precision-cut laboratory consumable essential for the preparation of asphalt specimens using the Marshall method. These paper discs play a critical role in preventing the hot bituminous mixture from sticking to the base plate or compaction hammer of the Marshall mold during the compaction process. By providing a clean, non-stick interface, they ensure that every specimen is removed intact and with a perfectly smooth, professional finish, ready for stability and flow testing.

Engineered for Reliability and Precision

Each Marshall Paper Disc is manufactured to strict dimensional tolerances, measuring exactly 100mm (3-15/16 inches) in diameter and 0.2mm in thickness. This precise sizing ensures a perfect fit within standard 4-inch Marshall molds, eliminating the risk of paper bunching or tearing during high-impact compaction. Our discs are made from a high-density, heat-resistant paper stock designed to withstand the elevated temperatures of hot-mix asphalt (HMA) without degrading or losing structural integrity.

Compliance and Laboratory Standards

Maintaining consistency in your laboratory workflow is vital for accurate data reporting. The CANTROL Marshall Paper Discs are designed to be fully compatible with the requirements of ASTM D6926, ASTM D5581, and AASHTO T 245. Whether you are using a manual hand compactor or a fully automatic Marshall testing machine, these discs provide the reliable performance needed to maintain compliance with international paving material standards.

Efficiency and Packaging

Supplied in a convenient 250-piece package, these discs are an economical solution for high-volume pavement laboratories. The ease of use significantly speeds up the sample preparation cycle, allowing technicians to focus on compaction accuracy rather than mold cleaning.

Key Benefits:

• Non-Stick Surface: Prevents sample adhesion to metal components.

• Heat Resistance: Formulated to handle standard asphalt mixing temperatures.

• Uniform Thickness: Ensures zero impact on specimen volume or height calculations.

• Standard Fit: Perfectly compatible with all 4-inch (101.6mm) Marshall mold sets.
