The objective of the project was to study the effect of surface shear on the performance of pavements. This was achieved through the collection and analysis of three data sets. Firstly, background information was reviewed providing information on tyre-pavement interaction, pavements design and failure mechanisms. Secondly, field data was collected from four roads and comprised photos of vertical deformation taken regular intervals, assessment of ride quality and movies of vehicles braking and accelerating on the roads. Lastly, a parametric study was carried out using the finite element analysis program SIGMA/W.

The findings confirm that vehicles accelerating and decelerating impose additional stresses within the pavement and consequently result in additional vertical deformation subject on the level of horizontal stress. However, at the investigated intersection the total vertical deformation was within limits specified in Austroads demonstrating that, current design methods are suitable for the design of pavement in areas that experience high surface shear.

To validate these findings further, additional research in this area would be required.
