In the modern era of civil engineering, the transition toward Polymer Modified Bitumen (PMB) has become the global standard for high-performance road construction. However, the inherent challenge of "phase separation"—where polymers and bitumen segregate during high-temperature storage—remains a critical bottleneck. As a leading Asphalt Storage Stability Tester supplier, we address the industry's need for precise measurement of this separation to ensure road longevity and safety.
Storage stability testing (following ASTM D7173 or EN 13399) is not merely a compliance step; it is an essential diagnostic tool. Our testers simulate the vertical separation of polymers under static storage conditions. By analyzing the softened point differences between the top and bottom of a heated tube, engineers can optimize chemical cross-linking agents and blending protocols, effectively preventing premature rutting and cracking of road surfaces.
Governments worldwide are increasing investments in "Smart Infrastructure." Our solutions integrate into the broader macro-economic goal of sustainable urbanization. By ensuring bitumen stability, we reduce the frequency of road maintenance, thereby lowering the carbon footprint associated with heavy machinery and asphalt production. We provide the technical foundation for "green" highways and durable airport runways.

A: PMB is a multi-phase system. Without proper stability, the polymer (like SBS) will float or sink during storage, leading to inconsistent asphalt mix and potential road failure. Our tester identifies this risk before the material leaves the plant.
A: Yes, our storage stability testers are designed with interchangeable components and adjustable software settings to meet both ASTM D7173 and EN 13399 protocols.
A: As a dedicated factory-direct supplier, we maintain a robust inventory of standard components, typically fulfilling wholesale orders within 2-4 weeks, depending on customization requirements.
A: We offer comprehensive virtual training and detailed technical documentation. For large-scale laboratory installations, we can dispatch engineers for on-site calibration and staff training.
