  • Does adding anionic polyacrylamide improve soil aggregation?
  • Adding anionic polyacrylamide (PAM) to soils stabilizes existing aggregates and improves bonding between and aggregation of soil particles. However, the dependence of PAM efficacy as an aggregate stabilizing agent with soils having different clay mineralogy has not been studied.
  • Can a polyacrylamide-based additive stabilize pavement construction materials?
  • Therefore, this study has been carried out to better understand the benefits of using a polyacrylamide-based additive (PAM) in stabilizing pavement construction materials. In this study, a synthetic PAM was used to stabilize three types of soil used in unsealed pavement construction.
  • What are ionic polyacrylamide (PAM) polymers used for?
  • Anionic polyacrylamide (PAM) polymers used in the study are polyelectrolytes mainly used for the decontamination of water. Polyelectrolytes conduce to precipitation and agglomeration and are often used in wastewater treatment plants.
  • Does Pam improve structure and aggregate stability?
  • The effectiveness of PAM in improving structure and aggregate stability was directly related to clay activity and to soil conditions affecting PAM adsorption (e.g., electrolyte resources, pH, and exchangeable cations) to the soil particles and inversely to the inherent aggregate stability.
