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.
