Rutting and Roughness of Flood-Affected Pavements: Literature Review and Deterioration Models

Sultana, Masuda / Chai, Gary / Chowdhury, Sanaul / Martin, Tim / Anissimov, Yuri / Rahman, Anisur

In recent years, flooding has caused disruptions to road management by significantly increasing rehabilitation costs. To date, there is very limited literature addressing the rapid deterioration of pavements immediately after a flooding event. This paper presents a state-of-the-art review of the literature on assessment and modeling deterioration of flood-affected pavements. Twenty peer-reviewed journal articles and conference papers and nine published reports are reviewed. Very few studies have attempted to incorporate flooding events on pavement condition. The critical review of the literature discusses the contributions and limitations in the assessment of flood-affected pavements to date. It also discusses the research conducted on the development of new deterioration models specifically for flood-affected pavements and the importance of developing such models for the road management system. Because there is no deterioration models for rutting and roughness of flood-affected pavements, this paper also presents two mechanistic-empirical deterministic based models for deterioration of rutting and roughness of flood-affected pavements. These models are sufficient to be used by other road agencies after calibrating for local road conditions. The outcomes of this paper will guide future research and help to understand the impact of flooding events on rapid deterioration of pavements. The newly developed deterioration models will help road agencies make effective decisions for the rehabilitation and management of flood-affected pavements.
