Lay Summary (English)

Lead
Lay summary
In engineered geosystems, such as compacted ground in road construction, soil properties vary spatially and it is widely accepted that probabilistic approaches to model this variation are more adequate than deterministic ones. On the other hand, it is essential to appropriately characterize soil stiffness and/or deformation properties for earthwork and pavement planning, for example. For that purpose, modern earthwork compaction rollers are equipped with sensors that allow a virtually continuous flow of soil property measurements, that can be linked with a positioning mechanism, like a GPS, to obtain the spatial distribution of the soil property. This project aimes at developing statistical methodologies and techniques for quality control of the compaction process and, ultimately, for intelligent compaction.

Abstract

In this project we attempt to develop complex state-space models for spatial data that are (i) observed indirectly through non-linear measurement operators, (ii) highly non-stationary, (iii) inherently multivariate with dynamic, complex correlation structures, (iv) subject to spatial misalignment and non-linear change-of support characteristics, and are (v) collected in huge quantities. Such data are, for example, collected by modern earthwork compaction rollers which are equipped with sensors allowing a virtually continuous flow of soil property measurements. The statistical methodology that will be developed in this project can subsequently be used for the design of an intelligent continuous compaction control system.
