Feasibility of Using Anti-stripping Additives as an Alternative to Hydrated Lime
Moisture damage in asphalt (also known as stripping) can significantly reduce the durability and strength of asphalt pavements, often resulting in expensive repairs. Hydrated lime is widely used in Australia to reduce the moisture susceptibility of asphalt mixes in service; however, potentially more sustainable additives (such as liquid anti-stripping agents) are also widely used internationally to reduce the risk of moisture damage in asphalt pavements.
Austroads has completed a project that investigated the use of alternative anti-stripping additives (other than hydrated lime) to reduce the moisture susceptibility of asphalt mixes in service.
An interim laboratory assessment protocol was developed to assess the effectiveness of different anti-stripping additives.
