In the competitive landscape of cold-mix asphalt production, the choice of cationic surfactant directly influences breaking rates, adhesion quality, and long-term pavement performance. Dihexadecyl Dimethyl Ammonium Chloride (DHDMAC), also known as dicetyl dimethyl ammonium chloride or N,N-Dihexadecyl-N,N-dimethylaminium chloride, has emerged as a critical additive for formulators seeking precise control over emulsion stability and aggregate coating. This article examines the chloride ion interaction, breaking rate control, and practical formulation strategies for integrating DHDMAC into cold-mix systems, with a focus on achieving performance parity with established benchmarks like Aliquat 206.
