Intelligent Compaction Technology for Geomaterials: A Demonstration Project

Abstract

Intelligent Compaction (IC), which is a part of Com paction Management, is a real time automatic adjust ment and continuous compaction control technology of geomaterials or asphalt layers. The adjustment of the compaction parameters by the equipment is conducted simultaneously to the compaction process, as well as the continuous measurement of a dynamic compaction value, which is an indicator of the material’s degree o f compaction. This study seeks to assess the advantag es and disadvantages of IC, as well as formulating a comparison with conventional compaction methods in terms of efficiency. This goal was achieved through in situ application of various technologies to two dis tinct types of material: a soil-rockfill mixture an d a sandy soil. Data was obtained and analysed by the IC continuous information, as well as by the application of seve ral different conventional compaction control tests and methods. Results show that the IC technology prese nts a superior performance, as well as various advantages when compared to conventional compactors.
