The use of the in-situ CBR apparatus on large road
construction projects has increased considerably in recent years. This
apparatus, mounted on a rolled steel joist cantilevered from the back of the
truck or fitted to the underside of a mobile frame, can be used to determine
the bearing capacity of soils quickly and efficiently. This method of
testing in-situ, using piston penetration, is useful for determining the
load carrying capacity in the field, when the in-place density and water
contents are such that the degree of saturation is 80 % or greater, when the
material is coarse grained and cohesion less so that it is not affected by
changes in the water content and when the material has been in place.
