After stabilization is completed and compaction finished the surface of the stabilized layer is roughned using normal street sweeping mechanical brooms (Figure 5.46). This needs to be done within a few hours of stabilization.
The finish that can be achieved is shown in Figure 5.47.

This type of finish is especially suitable for low intensity traffic areas. The surface layer is either impermeable or, extremely low permeability so appropriate run-off control measures have to be put in place. The surface is rather hard but depends also on the type of the soil which has been stabilized. Skid resistance is good to moderate. Wearing resistance under low intensity traffic is good.
5.9.5 Chip and Spray Finish
Chip and Spray Finish is a rather cost effective option even for high intensity traffic areas and is an effective and economic replacement for traditional asphalt finishing. Depending on the intenisty of expected trafic it can be applied in one two or three layers. It is most effective if it is applied within 24 to 48 hours following the completion of the soil stabilization with RoadCem. (Figure 5.48)
