RESEARCH

Research

Research Project ideas were initially based on proving that the new developments were tried and tested in the field in a scientific manner so direct comparisons with the old versus the new could be made.

Research Projects

When appointed as National Surfacing Engineer for Fulton Hogan a major focus was maintaining a technical lead in the key areas of surfacing. All Internal projects were initiated by problems identified by clients or staff they included:

Skid Resistance, Variable Application seal design, PAVEtex, Sustainability, High Friction Surfacing

Many of these projects were completed by the development of the solution, completing trials, writing technical papers and presenting at Roading road shows and conferences around the world showing the success of the solution.
