North Dakota Cone: 2720 (Part Xxxii)- Engineering Lab Training Systems Description and Tender Specification:

North Dakota Cone 2720 (Part Xxxii)- Engineering Lab Training Systems.
Developed by the North Dakotra Highway Department for use with a pavement design method similar to that associated with the California Bearing Ratio Test. This test is simple and more rapid than the latter and can be easily applied in site field test. The instrument consists a rod carrying a loading platform at the top and a hardened. steel cone at the bottom. The rod is mounted vertically and slides freely up and down in the collars of the frame and can be locked In any position as required. The conical tip penetries the soil through an aperture in the cast iron base. The loading platform carries a graduated plunger which enters one of the slide supports and permits the reading of the penetration correct to 1 mm (without weight). Set of 7 weights 5 kg. eachfor use with the above.
