minimizing rutting is mainly by eliminating the causes of rutting. this can be achieved by
1- grading of soil and mix design.( well graded soil= dense soil= low settlement)
note: well graded soil (100%) is not preferred (void ratio is needed to prevent bleeding of AC)
2- fine particles lead the mix to slide especially if AC content is more than recommended.
thank you Mr. jafar
Rutting in the pavement layer is the appearance of a drop in the layer in form of channels along the route of highways.
Possible reasons
The weakness of materials or poor materials mix design in compression layers, in addition to inadequate compaction during construction, smoothness of the asphalt concrete, softer materials, substrates as a result of water leakage or shocks tires (Studded tires), thickness of the pavement, heavy loads and the continuous stooping of the trucks on the road surface are all Contributes causing rutting.
It can prevent the occurrence of such defects: -
1-quality design mixtures
2-quality aggregates
3-using a quality asphalt runny layer(Tak-coat or Prime-coat) for adhesive between the layers
4-use rate of polymer asphalt
5. enough healthy discharge
I think we can use (Super pave) way because it has a lot of functions that make pavement stay for long time with rutting.
