Gravel
resheet performance is listed by life cycle costs ($/m2/yr) in order from lowest
to highest for resheets that have reached their end of life.
Also shown are the key variables affecting life cycle cost identified in
pilot council testing. The road conditions prior to resheet is an indication of the
end of life of the resheet.
Care
is to be taken in interpreting the performance reports as there are many
factors, which affect life cycle costs including availability and cost of gravel
materials, haul distance and modification of materials grading.
