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.

地质结构，如公路和铁路基地遭受水引起的损害，因为它们很容易与大气和浅水潜水面相互作用。 在交通荷载作用下，土工材料的强度和刚度受到持续的湿度变化的影响，土工结构的破坏表现为开裂、车辙和粗糙度。 如果能找到有效的方法来减少这种损害，就可以为社会节省大量的费用。 该项目提出研究一种新技术，其中使用疏水性聚合物添加剂的共混物来增加经受不同湿度水平和交通负荷的岩土材料的稳定性。
