Compaction reduces the volume of soil layers, aggregates, asphalt, and air voids. In the conventional compaction method, quality control is an issue since tests are limited to very specific locations, the actual amount of compaction needed is unknown for the operator at the real-time, and properties measured by devices are limited to outbound layers only. While Intelligent Compaction (IC) is a smart technology that provides 100% surface coverage over pavement compaction. Therefore, the quality control and consequently the uniformity of the layer will be significantly improved. IC technology applies to both soil base and asphalt concrete construction. It is also expanding the life span of the roadway. IC is performed by IC rollers equipped with the following: accelerometer, accurate Global Positioning System, Infrared Temperature Sensors, and onboard screens that continuously analyze compaction data. This system collects vibration amplitude and frequency data, roller speed, eccentric force, number of passes and real-time asphalt surface temperature. An accelerometer provides Intelligent Compaction Measurement Value (ICMV). ICMV is a measurement of material stiffness. The utilization of IC technology improves the accuracy of quality control. However, contractors and project owners are yet concerned about the cost efficiency of the approach. This study covers Life Cycle Cost Analysis (LCCA) and Life Cycle Assessment (LCA) of IC and Conventional Compaction. Several analyses are performed over a construction project, it is concluded that IC technology, can optimize agency, user and maintenance cost, construction time, reduce air emissions, and reduce resource usage.
