Introduction
The CBR-penetrologger is a device specially designed for measuring the CBR value (= Californian Bearing Ratio)
of the soil; at the same time this instrument automatically saves the measuring results obtained and thus makes
possible their further processing on a PC.
The penetrologger is distinguished by an ergonomic design, its low weight and its user-friendliness. It permits
measurements up to a depth of 70 cm. The penetrologger displays the CBR value for each measurement.
The penetrologger contains a GPS system for exact determination of the measurement position. The coordinates
displayed by the penetrologger can be allocated with the aid of certain sotware (or somewhat less accurately
over the Internet) to a site or a map.
Optionally a soil moisture sensor (Art.-No.: 061550) can be connected to it in order to determine and save the
soil moisture percentage (single-point measurement) of the measuring position.
The penetrologger permits the direct storage and processing of 1500 measuring data (CBR data including GPS
and soil moisture data). For this reason this instrument is suitable above all for comprehensive test series.
The penetrologger possesses a built-in arrangement for displaying the penetration speed, as a too-quick or
impact method of advance will result in values that are not representative of the measured soil. This method
is precise and possesses a measuring range of von 668 N (15% CBR).
1. CBR (Californian Bearing Ratio)
The Californian Bearing Ratio investigation (short CBR) is a method of testing with the help of which the
carrying capacity of soils and hydraulically bound layers (rather seldom) can be investigated. The procedure
was originally developed for compaction of airport surfaces and is meanwhile also used in road construction.
It was developed by the “Californian Department of Transportation“. Basically the investigation displays the
force needed by a plunger pressed into a sample of soil in order to achieve a defined penetration speed up to
a defined depth. The better the carrying capacity of the soil sample, the higher the generated plunger pressure.
A soil CBR value is an index of the shear resistance under standard loading as compared to the shear resistance
of a standard material (crushed limestone) under the same loading.
The CBR investigation is described in the MIL CRD-C 654-95, ASTM Standards D1883-05 (for samples prepared
in the laboratory) and D4429 (for field soils) and AASHTO T193.
It is necessary to carry out measurements in depths, taking into account deviations, of the soil capacity for air
trac with and without prepared start and landing strips.
The measuring results of the penetrologger are validated in order to characterize the CBR values of the soil as
described in the TTRL Report 901.

1.1 Average CBR value; calculation per penetration
The penetration depth (70 cm) is divided into 5 customer-specific,
adjustable depths. The CBR value (1 to 5) is measured at these depths.
CBR 1 (first value) and CBR 5 (last / deepest measurement) are the
determining CBR values and saved as individual values per cm. Values
2, 3 and 4 are supplementary information.
1.2 Inluence of the soil moisture content and the
content of the organic contents
The penetration resistance of the soil depends, among others, on the
soil moisture content. The higher the degree of moisture of the soil,
the lower its penetration resistance and the lower its carrying capacity.
In the comparison of penetration resistances that are measured at
dierent points in time (for instance before and ater a particular soil
processing), one must ensure that the soil moisture conditions during the
measurement are comparable. In practice, comparable moisture values
are best ensured in that the penetration resistance is determined at field capacity (pF-2). The soil moisture
content of the measuring point can be defined and saved with the aid of the optional soil moisture sensor
(Art.-No.: 061550).
1.3 Influence of the spatial variability
In the determination of the penetration resistance the spatial variability of the soil must also be taken into
account. The dierences with regard to texture, the structure or content of organic content can dier substantially
on a parcel level. As all these factors determine the penetration resistance, it is first necessary to make repeat
measurements in order to receive a representative value. The number of necessary repeat measurements is
oriented to the desired precision and the natural variability of the soil. The literature (for instance Campbell &
O’Sullivan, 1991) recommends 10 measurements per plot because of the soil formation due to the impression of
the cone. The spacing between the individual measuring points is at least 50 to 60 cm. The Netherlands standard
for electrical penetrations (NEN 5140, 1996) promotes a spacing of at least 100 cm between penetrations.
2. Description
The CBR penetrologger is normally supplied as a complete set for measurements to a depth of up to 70 cm. Such
a set is comprised of the penetrologger itself, suitable CBR cones, conecheck key, probe rods, a depth reference
plate, cable, sotware and a test protocol. Accessories such as soil moisture sensor (061550) are obtainable as
option. All these parts are packed into a carrying bag.
The complete penetrologger (see picture) consists of a housing (a) with GPS antenna (7), a LCD display (8), a key
pad (9), a level (10), and a force absorber (2). The logger has a spray-water protected housing with hand grips
(11). The penetrologger is provided with power by means of batteries.
The cone-shaped point or “Cone” (4) is screwed on below the three-part probe rod (3).
When the cone is forced into the soil, the penetrologger registers the depth up to 70 cm with great precision
by means of an internal ultrasound sensor whereby the depth reference plate (5) comes into use.
The measured penetration resistance, the GPS data and – if the optional soil moisture sensor is connected to the
communication port (6) – the percentage of soil moisture are saved into the internal Logger of the penetrologger.
The average value of the CBR values and the standard deviation can be calculated automatically. If the cable
(13) is connected to the communication connection port (6) and to the PC, then data can be exchanged between
the Logger and the PC. The accompanying sotware permits the reading out of the data to the PC, the graphic
and numerical representation and the printing out of the data.
The conecheck key (12) is used for checking the wear on the cones. The cone must be replaced when it fits
through the hole.

4. The procedure
Before starting the measurements with the penetrologger, a plan for the field measurements must first be
established (Chapter 5. Plan for field measurements). Such a measurement plan contains the definition of the
field measurement positions, the number of measurements that will take place at the individual measuring
points, and the settings of the penetrologger (for instance the speed of penetration).
If desired, the desired measuring plan can be created on the PC or on the penetrologger itself (Chapter 7. Creating
a plan with the aid of the penetrologger). Practically, it is more convenient to make use of a PC (Chapter 6. Creating
a plan on the PC). To this purpose the Penetroviewer CBR sotware needs to be installed on the computer. If
the PC is now connected to the penetrologger via the communication cable, then the created measuring plan
is transferred from the PC to the penetrologger.
Ater creating the plan, the penetrologger is ready for use and thus permits the measurement of the penetration
resistance. Now the prescribed measurement are carried out at each measuring point in the field (Chapter
8. Carrying out the measurements). The corresponding results are automatically saved in the logger where
there is an upper limit of 1500 measurement results. It is also possible to adapt the measurement plan in the
penetrologger on site (Paragraph 7.4).
The measuring results can be called up on site on the penetrologger in graphic or in numerical depiction
(Chapter 9. Processing the measuring data). The sotware also permits the reading out of the data on the PC,
the processing of these data, transfer to other programs, and printing out on a printer.

5. Planning the measuring for field measurements
5.1 Creating a plan
This type of plan consists of a hierarchical structure
of projects, plots and penetrations (see picture).
A project consists of several plots (measuring
positions). A penetration resistance is determined at
each individual plot. In this, one or more penetrations
(measurements) are carried out per plot in order to
arrive at a representative average value for the plot.
The following general parameters are created for
each project:
Project designation
User name (e.g. BW)
Plot designation
Penetration speed
Number of plots
Quantity of soundings per plot (max. 20)

6. Creation of a plan on the PC
The creation of a plan on the PC and the later transfer to the penetrologger has the advantage that the entry via
the keyboard of the PC is oten easier. This method saves much time, especially when special plot designations
are to be used, which can be time-consuming as regards the typing eort. One or more projects can be defined
per plan, in fact up to a maximum of 1500 penetrations.
Several plans can be saved on the PC and these can be called up later as required. However, the penetrologger
can only save one plan. This plan can contain several projects. In the case that several plans are used in the
field, then it is advisable to use a Laptop.
