As a common description of the compaction process, density versus number of roller passes (coverage) is often found in the literature and is subsequently used in the field. The closed formula is introduced to quantify such a relationship. Variables considered are compaction density, mix viscosity, temperature, frequency, and amplitude, in addition to the number of roller passes. Their effects are included in the proposed formula. The experimental data found in the literature are used to verify the equation. Excellent prediction of the data confirms the success of the formulation. As the result of this mathematical modeling, the minimum number of passes required to finish a certain compaction job and the maximum compaction density achievable by a certain compaction operation are suggested. The equation and its features will be an effective tool for using rolling compaction in an effort to construct better roadway pavements.
