Durability of Asphalt and the Role of Rhinophalt Preservation

Air voids play a critical role in determining the long-term performance and durability of flexible asphalt pavements. They represent the small, interconnected spaces within the compacted mixture that are not filled by aggregate or bitumen. While some air voids are necessary to allow for binder expansion, temperature movement and traffic-induced densification – excessive or uneven air void content can have a major impact on pavement life.

RHiNOPHALT® Asphalt Preservation treatment is best applied when the asphalt is still in good condition, typically within the first five to eight years after the asphalt is laid. This timing ensures the preservation treatment can effectively penetrate and protect the asphalt from oxidation, UV degradation, and water ingress before significant wear and tear occur.

For anyone that has seen the latest ALARM survey, they will know what we mean when I say it makes stark reading. The backlog for road maintenance has now reached the point where more than half of the local road network in England and Wales is reported to have less than 15 years’ structural life left as the amount needed to fix the backlog of carriageway repairs increases to a record high of £16.3 billion.
