Nulear measurements the density of layers in pavement structures – BRRC information leaflet CRR F74

It has been quite a few years since nuclear measurement methods made their appearance in road construction to check the density of various materials in pavement structures. Yet there has been no proper breakthrough of such measurements in Belgium to date, whereas our neighbours have used the method sucessfully for several years.

Plate-bearing test for compaction control in road engineering – BRRC information leaflet A26

This operational precedure describes a plate-bearing test for checking the quality of road construction materials after laying (compaction control) or the residual quality of a fatigued road layer.

German dynamic plate – BRRC Information leaflet F70

This device was originally developed in Germany and is used to determine the dynamic deformation modulus of embankments and base layers in road construction.

Light percussion sounding apparatus – BRRC information leaflet A25

A significant correlation between test results from a percussion sounding apparatus and the California Bearing Ratio (CBR value) has been established for fine soils ranging from silt to fine sandy soils I (D < 0,2 mm).

In a standardized form this equipment and test method can render invaluable services:
