Does polyacrylamide protect soil resources?
Use of soil amendments, including anionic polyacrylamide (PAM), is one of many options for protecting soil resources. Polyacrylamide has been the focus of a substantial amount of research in the 1990s. Our objective is to present a review of the recent findings and advancements in PAM work.
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.
Does polymer polyacrylamide increase soil strength?
The polymer polyacrylamide have very good properties and specific amount of PAM that can increase the strength of soil in the base coarse. Using polyacrylamide on index properties of soil and carrying out two different soil samples and the result is compared.
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.
