Ageing of hot mix asphalt

Ivica Androjić

Sažetak

An overview of current surveys related to the ageing of placed hot mix asphalt and asphalt pavement courses is presented in the paper. Asphalt ageing occurs as a result of external and internal factors. Internal factors include bitumen content in the mixture, thickness of bitumen layer enveloping aggregate grains, air void content, and properties of aggregates and binders. All factors affecting the ageing process of binders and asphalt mixtures are described in detail, including also some of the existing models that are presently used to predict ageing of produced and placed asphalt.
