Developing Transfer Functions between Intelligent Compaction Roller and Lightweight Deflectometer Data
This study proposes a transfer function that relates the surface displacement under a lightweight deflectometer (LWD) with the surface displacement under a vibratory roller. LWD is a practical tool that is used for assessing the modulus of the compacted sections at randomly selected locations. One advantage of intelligent compaction (IC) technology over the spot tests is the assessment of uniformity and consistency of compaction over the entire compacted section. This study utilizes a database containing a comprehensive range of soils with diverse nonlinear parameters. Both single-layer (subgrade only) and dual-layer (base and subgrade) geosystems with different base thicknesses subjected to LWD and IC roller were included in the database. The deflections obtained from the LWD and IC roller were then related to one another using a genetic programming (GP) algorithm. The results show that the proposed relationship effectively relates the surface displacements from the two devices.
