anionic polyacrylamide (pam) application

ANIONIC POLYACRYLAMIDE (PAM) APPLICATION

CODE 450 (ac) DEFINITION Application of water-soluble anionic polyacrylamide (PAM) to the soil. PURPOSE This practice is used to accomplish one or more of the following purposes: Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth.

Stabilization of Subgrade Soil Using Polyacrylamide-Based

In this study, a synthetic PAM was used to stabilize three types of soil used in unsealed pavement construction. Unconfined Compressive Strength, California Bearing Ratio and erosion tests were conducted to evaluate the performance of soils treated with PAM.

Chemical Stabilization - U.S. Environmental Protection Agency

Description Chemical stabilizers, also known as soil binders or soil palliatives, provide temporary soil stabilization. They are readily applicable to the surface of the soil, can stabilize areas that cannot establish vegetation, and provide effective protection from wind and stormwater erosion.

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

Figure 1. Granular or powdered PAM formulation is used primarily in hydroseeding. Erosion Control The erosion process is initiated when a rain droplet impacts the soil surface and dislodges soil particles. Once overland flow begins during a heavy or prolonged rain, these soil particles are then washed downslope.

Stabilization of Clays and Clayey Soils Using Polycom-A

1 Introduction Traditional additives such as lime and cement have been used all over the world to stabilize sealed and unsealed roads. Traditional additives have shown to improve soil workability, strength, durability and often lead to a reduction in the design thickness of the structural base layers.

Polyacrylamide (PAM) - State of Michigan

Definition Polyacrylamides (PAMs), are polymer-based materials used to facilitate erosion control and decrease soil sealing by binding soil particles, especially clays, to hold them on site. In addition, these types of materials may also be used as a water treatment additive to remove suspended particles from runoff. Description and Purpose
