Average molecular structure models of unaged asphalt ...

Aug 07, 2021  Asphalt binder is a complex compound comprising a diverse and intricate range of hydrocarbons which makes it difficult to accurately ascertain its chemical structure. This study aimed to analyze the chemical composition of asphalt binder and establish an accurate molecular structure model of unaged asphalt binder fractions. An unaged asphalt binder was separated into four fractions based

Gradation-Based Framework for Asphalt Mixtures

2013 (English) In: Materials and Structures, ISSN 1359-5997, E-ISSN 1871-6873, Vol. 46, no 8, p. 1401-1414 Article in journal (Refereed) Published Abstract [en] Aggregates are the major component of asphalt mixtures, greatly influencing the mixtures resistance to failure. The structure that is formed by the aggregates will depend mostly on the size distribution, shape and mineral composition.
