Confocal Laser Scanning Microscopy - Observation of the Microstructure of Bitumen and Asphalt Concrete

Confocal Laser Scanning Microscopy (CLSM) has gathered interesting new results regarding the microstructure of bitumina as part of a comprehensive study on bitumen and asphalt concrete. Compared to normal fluorescence microscopy, the CLSM technique has been proven to be the method of choice for bitumen. The main advantage is a much stronger fluorescence signal due to the higher intensity of the...

Characterisation of Asphalt Concrete Using Nanoindentation

In this study, nanoindentation was conducted to extract the load-displacement behaviour and the nanomechanical properties of asphalt concrete across the mastic, matrix, and aggregate phases. Further, the performance of hydrated lime as an additive was assessed across the three phases. The hydrated lime containing samples have greater resistance to deformation in the mastic and matrix phases, in...

A Notched Disk Crack Propagation Test for Asphalt Concrete

Cracking is a major distress in asphalt pavement which can lead to premature pavement failures and can cost agencies millions of dollars in maintenance and rehabilitation costs. Even with modern advances in pavement engineering, attempts to quantify and model cracking in asphalt pavements have proved extremely challenging; this is due to the visco-elastic behavior of asphalt concrete and the co...
