Course Description: AEC Daily: Permeable Walkways with Decomposed Granite and Natural Aggregate Pathway Materials
Parks, recreational areas, and common rural and urban spaces can be essential relaxing oases. Pathways that navigate through these public spaces should be functional and durable and complement the natural environment. This course explores pathway materials and focuses on decomposed granite (DG) and natural aggregates. It discusses the types of pathways, their applications, installation, and maintenance, as well as their contribution to green design.
Describe the benefits and drawbacks of a variety of pathway materials and the key considerations in the material selection process relating to the environment, traffic load, costs, and design goals.
Explain how decomposed granite (DG) and natural aggregate pathway materials support the goals of low impact development and contribute to meeting green design objectives.
Compare three different types of DG and natural aggregate pathways in terms of materials, performance, and suitable applications.
Discuss the installation and maintenance procedures applicable to each type of pathway to ensure a safe, functional, and durable installation.
