The time and effo rt required to prepare specimens for

compact ion studies and other test methods can oft en be

costl y and time-consuming.The use of an automat ic,

mechanical compactor will show considerable cost benefit s

over hand compaction methods.Two models meeting the

requirements of BS and ASTM are available.

Both these tests incorpo rate a M oistur e Condit ion

Apparat us.The M CV is a measure of t he minimum

compactive effor t required to produce near full compactionof a soil.The CCV measures the rat e at which a samp le of

chalk lumps are crushed. Used wit h the saturat ed moistu re

content of chalk , CCV can be used to classify chalk as a fil l

material.

The original M oisture Condition Apparatuswasdeveloped by the

Transport Research Laboratory, England.ELE hasredesigned the

equipment to give improvementsin termsof strength and

reliability, particularly under site conditions.The ELE model isT RL

approved and is used in construction control to assessthe

suitability of earthwork material in relation to the specified upper

limitsof moisture content. In a second mode of operation, it

determinesa chalk crushing value for use in classification of chalk

asa fill material.

To assessthe suitability of earthwork material a moisture condition

value is determined. The test is based on the determination of the

minimum number of blowsof the rammer required to produce a

state of full compaction in a sample of soil.A fter calibration over a

range of moisture contents the suitability of earthwork materialcan be assessed without the measurement of the moisture content

of the soil with itsassociated delays.T he chalk crushing value is

determined from the rate at which a sample of single-sized chalk

lumps(passing 20 mm and retained on a 10 mm BS sieve) is

crushed under the impact of the rammer.T he chalk crushing value,

taken together with the value of the saturation moisture content of

lumpsof the chalk, givesa classification in termsof the likely

behaviour of the chalk during construction.

O peration of the apparatusis extremely simple.The rammer is

lifted, when it reachesthe top of its travel, a striker attached to the

crossmember releasesthe automatic catch allowing the rammer

to fall.T he rammer hasa scale for measurement of penetration

into the mould.A fter each blow, the height of drop can be reset

and checked by meansof the vernier gauge supplied.To record thenumber of blows, a counter isfitted to the release mechanism.

fibre discs, operating instructions and standard formsfor

determining Moisture C ondition Value and Chalk C rushing Value.

The Califo rnia Bearing Ratio test, or CBR test as it is usually

termed, is an empirical t est f irst developed in Califor nia,

USA, for estimat ing the bearing value of highway sub-bases

and subgrades.The test f oll ows a standardised procedure

and t here is litt le diff erence betw een BS/EN and ASTM

tests. However, there are numerous ways of pr eparing

sampl es and i n t his respect American p ractice dif fers in

detail from British practice.

This test can be performed in the laboratory on prepared samples

or in-situ on location. It is important to appreciate that this test,

being of an empirical nature, is valid only for the application for

which it wasdeveloped, i.e. the design of highway base thicknesses.
