Abstract
A method of compacting a roadway section includes entering initial input parameters into a compaction analyzer. A plurality of passes is made with a roller over a portion of the roadway section and vibratory energy is applied thereto. Responsive vibration signals are gathered and the compaction analyzer generates estimated density signals. Actual density measurements are taken and the estimated densities are compared thereto. Selected ones of the initial input parameters are adjusted so that an adjusted density output signal which represents the actual density of a roadway section is generated.
