Our primary goal is to improve the process of design verification of compacted materials to ensure quality, performance and durability using a combination of proof rolling (with or without intelligent compaction) and modulus-based devices. In close collaboration with our TxDOT partners, the research team will utilize our current expertise gained from several recent and ongoing intelligent compaction projects and our NCHRP project on the effective use of the modulus-based devices to develop practical test protocols and specifications to improve the design verification during construction.
