Workshop Spotlight: Introduction to Soils and Aggregates
Introduction to Soils and Aggregates
May 3, 2022
8:15am EST – 4:00pm EST
This course will cover the basics of soils, or what you need to know about soils to be able to properly work with them. Content will include soils as a 3 phase medium, Atterberg limits, sieve analysis, proctor testing, and field compaction techniques.
Beginners and employees that are not exposed to current soil and aggregate industry practices
Part 1: Basic Soils
- Soils 101 – soils are a 3-phase material, they are a natural material, we use a lot of empirical data to predict what soils will do, terminology we use to describe soils (particle size – clay, silt, sand, gravel), Sieve Analysis, Soil Classification
- Soils and Water- talk about the effect that water can have on soils, particularly fine-grained soils. Go over plasticity and Atterberg limits and what they mean when working with soils.
Part 2 – Compaction of Soil
- Compaction and Strength – Relate how the density / degree of compaction of a soil effects that soils strength and permeability. – Talk about void ratio and how we generally want soils to be compacted close to their maximum dry density.
- Proctor Testing – Describe the process of Proctor testing and how maximum dry density and optimum water content is calculated.
- Field compaction – Go over some best practices for compacting in the field to ensure we approach the maximum dry density.
