Since AMW first adapted its GPS machine control software for landfills in the early 2000s, I’ve had the pleasure of speaking with numerous waste management professionals around the world. Based on my own decades of experience in construction, and through hundreds of conversations with landfill operators, I’ve come to understand these six points as the most important rules of engineered fills:
Know the material. Understand the waste stream, and its fluctuations of quantity and makeup.
Measure the moisture content precisely, and know how it relates to the current waste stream.
Road paving operations, whether on major highways or small local routes, are a process that everyone on the roadway is an expert in. They can tell if the base was constructed properly because the road maintains its designed shape, and easily see and feel potholes created by drainage problems. Anyone behind the wheel can tell if the pavement was properly designed and installed by observing its longevity and, probably the most evident, by the ride quality.
Whether a tile system, earthworks, paving project or landfill, there are three common threads in planning a successful project:
1. A high accuracy topographic map of the project area is critical. Depending on the scope of the project the designer can use photogrammetry, GPS mobile mapping, LIDAR, or standard data collection methods. Background imaging and existing data can also be incorporated for more detail.
