Abstract:Asphalt is the most widely used road paving material. It has become this popular because it is durable and still flexible. There are also a wide variety of asphalt mixtures, each having a different mixture design for a different purpose. Simply put, asphalt is a mixture of aggregate and bitumen binder. When manufacturing asphalt choices need to be made regarding the aggregate types, aggregate size, aggregate proportions, bitumen amount, air voids amount, and other additives which give the asphalt other features, for example, decreased stiffness. In this paper the methods literature study, expert interviews and empirical study are employed to answer the question: What relation is there between asphalt processing, particularly compaction and temperature homogeneity during paving, and the asphalt’s ultimate lifespan? The literature study and expert interviews focuses on gaining a background understanding and theoretical understanding of the topic and phenomena at play here. Then data from two case roads (the A35 and Aziëhavenweg) will be used to find an answer to the main research question.
