Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations.

Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if effective methods can be found to minimise such damage. This project proposes to study a novel technique, in which blends of hydrophobic polymer additives are used to increase the stability of geomaterials subjected to varying moisture levels and traffic loading.Read moreRead less

Summary
Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring tog ....Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring together a multi-disciplinary team with complementary strengths to provide an integrated solution for rehabilitation of structures. The core of the network focuses on design tools, linking the various technologies to provide appropriate rehabilitation and understanding of life cycle demands for major infrastructure.Read moreRead less
