A granular surface can be used with a traffic volume where the annual average daily traffic is 1, vehicles per day or less. The TMS layer adds no significant structural strength, and so is used on secondary highways with low traffic volume and minimal weight loading.
The decision whether to pave a gravel road or not often hinges on traffic volume. Concrete surfaces specifically, Portland cement concrete are created using a concrete mix of Portland cementcoarse aggregatesand and water.
