Thickness of embankment in road infrastructure

Thickness of embankment in road infrastructure

Normal embankment refers to the use of materials that less than 15% of its volume consists of pieces of aggregate larger than 15 cm.

The thickness of the rammed layers in the normal embankment should not generally exceed 20 cm. The use of greater thickness is subject to the use of suitable coarse-grained materials, conducting test pieces with the desired materials and with suitable rollers to achieve the characteristic density percentage, and the possibility of conducting standard tests to measure this density in the entire thickness of the implemented layer, which anyway It should not exceed 30 cm.

In the conditions that testing the entire thickness of the layer with a local specific weight determination test, or two tests each time in ½ (one half) of the layer thickness is not available, the thickness of the pounded layer should not exceed 20 cm, in this case, the depth The local test borehole should not be less than 15 cm.

In cases where it is not possible to use mechanical rollers due to their limited maneuverability, the thickness of the embankments should not exceed ten centimeters and the desired compaction percentage should be achieved with manual rollers.
