Areas of high environmental salinity are predicted to increase over the next 40 years in Australia, due to land use and climatic changes. This presents a risk to road assets as accumulation of salts within roads has been found to cause damage to thin bituminous surfacings. It is in this context that the present study explores the microstructural changes caused by environmental salt crystals accumulating within unbound granular road pavements. Fine-grained specimens were prepared by static compaction, immersed in different solutions, and finally either freeze-dried or oven-dried at 40 °C. The effects of different drying procedures and salinity on soil¿s microstructure were explored via mercury intrusion porosimetry and scanning electron microscope observation. Results suggest that a freeze-drying process can significantly modify the microstructure, which should be taken into account when conducting any microstructural analysis on high-salinity soil specimens.

This paper presents a new coating material [hand-spray plaster (HSP)] used to measure the bulk volume of soil specimens having irregular shapes. The new method has been validated against two benchmark methods, namely, the wax and plastic bag methods, by conducting swelling and shrinkage tests on intact Maryland clay. The results show that the new method yields similar values of volume but with much reduced data scattering. The HSP method is also far easier to use than the other two methods. Finally, the stiffness of the coating has been measured and its restraining effect has been found to be negligible. Some of the benefits of using the HSP method are: (1) limited fluid retention by the specimen postimmersion for volume measurement, (2) reduced water-intake rate with elimination of cracking upon swelling caused by high-suction gradients, (3) absence of the restraining effect on specimens upon swelling, and (4) accurate determination of the swelling and shrinkage curves with only one specimen per curve.
