Design QUESTION: What structural design process could I use for cement stabilisation of lightly trafficked roads?
Figure 8.4 of the Austroads pavement design guide may be used for modified cemented materials where the design outcome is to not have a bound materials. The layered elastic analysis approach is generally conservative for cemented materials because the standard equivalent axle load approach is too conservative based on experience and performance of such lightly bound roads in use in Australia. At this stage AustStab recommends the use of the following design chart from the AustStab guideline titled Interim pavement design guide for a cement stabilised base layer for light traffic.
