After 12 months of trials on the Lawrence – Tullymorgan Road, we're starting to see results from our unsealed road maintenance trials.
Over the next year we're planning to extend the trials to other sections of unsealed roads in other parts of the Clarence Valley to see how the various types of gravel material and gravel treatments perform over time, and in different conditions.
The trials will run for two years and the results will be used to determine how we manage and maintain our network of unsealed roads into the future.
Two sections of the Lawrence – Tullymorgan Road have been used to trial a range of surface treatments over a two year period from 2018-2020. Each road segment was brought up to an initial standard with 6% cross-fall on the road and 100 mm of local gravel. Various treatments were then applied to the gravelled sections, and monitored monthly.
