Bitumen/Asphalt

The AZA0936 Water in Bituminous Material (Dean–Stark) Apparatus from Azalab is a precision laboratory system designed for the accurate determination of water content in bituminous materials, including asphalt, road oils, cut-back asphalts, and related petroleum-based binders.

Water contamination in bitumen can significantly degrade material performance by causing poor adhesion to aggregates, stripping, foaming during mixing, and reduced pavement durability. Using the internationally accepted Dean–Stark azeotropic distillation method, the AZA0936 provides reliable, repeatable, and standard-compliant moisture determination, making it essential for quality control in road construction, civil engineering laboratories, and bitumen production facilities.
