Working platform design case study for heavy tracked plants Available to Purchase

This paper describes an innovative approach of proof rolling a large-scale construction site with associated testing and interpretation to enable the existing pavement to be used as the working platform to support heavy tracked plants. The existing pavement is underlain by granular fill, which may potentially be variable due to previous site development, and was classified as non-engineered fill. Proof rolling was successfully adopted and avoided the construction of a new working platform over a 2 ha site, which would have been time consuming and costly. Non-linear stiffness theory was used to enable a lower than ultimate and practical proof rolling pressure to be adopted. It is considered that the performance-based approach adopted on this project may be similarly applied to a range of other projects to derive economic solutions.
