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.

Why is polyacrylamide used as a base material for road work?

To enhance the properties of soil and reduce the cost of project, polymer was used as an additive for the improvement of a base material of the road work. Polyacrylamide (PAM) is one such polymer which have many advantages including reduction in permeability, an increase in durability and its provision of strength characteristics.

What are the environmental benefits of polyacrylamide?

Environmental benefits include reduced soil loss, reduced pesticide and fertilizer runoff. This enhances both soil and water quality, both on site and off site. Polyacrylamide is an alternative to traditional erosion control practices.

Which organic polymers are used in soil stabilization?

Many synthetic organic polymers have been used in soil stabilization in the past decades, including polyacrylamide (PAM), polyacrylates, poly (vinyl alcohol) (PVA), poly (vinyl acetate) (PVAc), polyurethane, aldehyde, propylene, etc.

Does polyacrylamide stabilize soil structure?

Costly repairs and reshaping of slopes as well as sedimentation and water pollution result in environmental and economic losses to the general public as well as the contractor. Polyacrylamide (PAM) can stabilize soil structure but does not remediate poor soil structure.

Can polymers be used for soil stabilization in pavement and geotechnical engineering?

This paper provides a review of the research on use of polymers for soil stabilization in pavement and geotechnical engineering. First, the properties impacting the effectiveness of widely used polymer classes, including geopolymers, biopolymers, and synthetic organic polymers are discussed.
