HDR Confirmation Presentation - Sahar Deilami

Abstract: Some researchers identified the composite pavements as a cost-efficient pavement type which may provide better performance for airfields and highway pavements with heavy traffic volume. However, the reflective cracking is known as the main weakness of this type of pavement by majority of the researchers. To ensure successful control of this distress mode, some treatment methods are suggested such as increasing the thickness of asphalt overlay, metallic grids, different types of geosynthetics, asphalt-based interlayers, fractured-slab approaches, stress absorbing membrane interlays (SAMIs) and crack and seat treatments. The main objective of this study therefore will be placed on modelling the reflective cracking mechanism in composite pavements for different loading and temperature regimes and developing a model based on the cohesive zone theory in fracture mechanics. This model will be also solved using a numerical finite element approach.

Bio: Sahar is a senior pavement engineer at GHD with more than 8 years’ experience in civil and pavement engineering in Australia and overseas. She has been performing as pavement engineer in several TMR projects. Sahar received her MPhil from Curtin University, with a thesis on the application of recycled material in pavement base courses. She is currently undertaking part time study towards PhD in the field of airport pavement engineering under supervision of Dr Greg White. She is experienced in flexible and rigid pavement design, spray seal design, materials engineering, pavement rehabilitation design, pavement investigations and asset management. She has a solid knowledge of different Australian standards and specifications.

We look forward to seeing you there
