Marshall Water Bath for Asphalt Specimen Conditioning

In the field of asphalt pavement testing, maintaining precise temperature control is critical for the integrity of your results. The CANTROL Marshall Water Bath is a premium laboratory heating solution specifically engineered for the conditioning of asphalt specimens. This high-performance system ensures that specimens are brought to the exact temperatures required for stability and flow testing, providing the consistency needed for high-stakes engineering projects.

Precision Engineering and Capacity

Designed for high-volume laboratory environments, this 30-liter unit is capable of holding up to 24 standard samples simultaneously. Whether you are preparing specimens for quality control or academic research, the bath ensures precise and uniform temperature distribution. Meeting the strict requirements of international standards such as ASTM D5581 and AASHTO T245-97, it provides technicians with the confidence that their specimen preparation is fully compliant.

Advanced Thermal Distribution and Insulation

A key feature of this Marshall Water Bath is its superior thermal management. The integrated mechanical stirrer, combined with an internal circulation system, eliminates “cold spots” by ensuring the water remains in constant motion. This guarantees a homogeneous temperature environment across every square inch of the tank. For maximum efficiency, the stainless steel internal tank is protected by a powder-coated steel exterior, separated by 50mm of high-density wool insulation. This rugged construction not only enhances safety but also allows for maximum heat retention during long testing cycles.

User-Friendly Control and Versatility

Operating the Marshall Water Bath is intuitive thanks to its digital thermostat and clear thermometer display. Users can easily adjust the settings from ambient levels up to 70°C, accommodating a wide range of asphalt binder types and testing protocols. The perforated stainless steel shelf keeps specimens elevated from the floor of the tank, allowing for unobstructed water flow around the specimens. This attention to detail ensures that the thermal transfer is both rapid and consistent, which is essential for accurate Marshall stability and flow measurements.
