Lignosulphonate used in Asphalt industry
Crack filling composition involving quaternary ammonium salt, aliphatic amine,ammonium lignosulphonate , imidazoline, and amide.
• Water stability of an asphalt mixture can be improved by
adding 0.3% lignosulphonate fibers.
• Asphalt‐emulsifying agent containing SW sodium lignosulphonate with
an av. mol. wt. of 200‐100,000 (sodium lignosulfonate ,and the lignosulphonate is that broad‐leaf pine or needle‐leaf pine) has the proper HLB value, slow
demulsification speed, proper frothing ability, and strong foam stability.
• Ammonium Lignosulphonate additive has been shown to provide a warm mix additive
that can modify the combination state of asphalt and stone material surface;
modifying the fluidity; and decrease production cost of the asphalt mixtures.
