Effects of aggregate properties on strength characteristics of the foamed bitumen mixture with relation to Western Australian roadway construction
MetadataShow full item record
Foamed bitumen is produced by injecting small amounts of cold water and air into a hot bitumen mix, typically at about 180°C. This thesis aims to determine an effective mix design for foamed bitumen for use in Western Australian conditions, based on mechanical testing using typical Western Australian aggregates, while altering the percentage of crushed rock base and crushed limestone as well as the fine contents and grading curves within the aggregate mix.

Bitumen II from the Paleoproterozoic Here’s Your Chance Pb/Zn/Ag deposit: Implications for the analysis of depositional environment and thermal maturity of hydrothermally-altered sedimentsHolman, Alex; Grice, Kliti; Jaraula, Caroline; Schimmelmann, A. (2014)The formation of sedimentary exhalative (SEDEX) Pb/Zn deposits is linked to ocean euxinia, but recent evidence suggests that ferruginous conditions may have dominated the deep ocean during the Middle Proterozoic, a maximum ...
A comparison of thermal maturity parameters between freely extracted hydrocarbons (Bitumen I) and a second extract (Bitumen II) from within the kerogen matrix of Permian and Triassic sedimentary rocksNabbefeld, Birgit; Grice, Kliti; Schimmelmann, A.; Summons, R.; Troitzsch, U.; Twitchett, R. (2010)In this study we compared various maturity dependent aromatic, steroid and triterpenoid hydrocarbonratios in bitumens that are freely extractable from sedimentary rocks (Bitumen I) with those in second extracts that ...
Efficiency of extraction of polycyclic aromatic hydrocarbons from the Paleoproterozoic Here’s Your Chance Pb/Zn/Ag ore deposit and implications for a study of Bitumen IIHolman, Alex; Grice, Kliti; Jaraula, Caroline; Schimmelmann, A.; Brocks, J. (2012)Demineralisation of a sedimentary rock with HF liberates a fraction of extractable organic matter (OM) that is not accessible with standard extraction techniques, which is known as Bitumen II. This fraction displays lower ...
