The role of proof rolling in pavement constructionKeynote Address

D. Mangan

Proof rolling of pavement subgrades is a key construction operation for all pavements but despite this there appears to be confusion about the process, the plant used and the evaluation criteria which is leading to subgrades that are adequate being condemned and having to be removed and replaced by stronger materials. The paper looks at the process and whether the plant currently being used as the proof roller is appropriate.
