Probe Mackintosh test Objective Collecting a disturbed soil sample for grain-size analysis and soil classification Determine sub-surface stratigraphy and identity materials present Evaluate soil density and in-situ stress conditions Estimate geotechnical parameters Theory The main purpose of the test is to provide an indication of the relative density of granular deposit such.
. Mackintosh Probe which has 30 cone penetrometer while JKR Probes has. Mackintosh probe test lab report. 2005 briefly report the main advantages of the Mackintosh Probe that are.
This is a like dynamic test and the cone is driven directly into the soil by driving a 5 kg hammer. Lift the hammer to the maximum position and then release. Mackintosh Probe The Mackintosh Probe has been described by Clayton et al.
Mackintosh probe test is widely used to assess soil bearing capacity mainly on soft ground M-value. Record the data for the number of blows for every 03m penetration into the Mackintosh Probe test form. Remove the hammer set and connect a new steel rod on top of the original rod in the final 03m.
127 mm diameter solid rods and a 45 kg dead weight with standard drop height. It consists of a 2794 mm diameter cone with a30-apex angle. Mark again the rod for every 03m interval.
Mackintosh Probe which is has 30 cone penetrometer while JKR probe has 60 cone penetrometer. The way to stamp the element of weight to the weight and pressure influenced the number of items in the earth auction. INTRODUCTION JKR Probe Test is a dynamic penetrometer test used to check the consistency of the subsoil.

Record the data for the number of blows for every 03m penetration into the Mackintosh Probe test form. JKR Probe test is a dynamic penetrometer test use to check the consistency of the subsoil.
It is a considerably faster and cheaper tool than boring equipment especially when the depth of exploration is moderate and the soils under investigation are soft or loose Mackintosh Probe which has 30 cone penetrometer while JKR Probes has 60 cone. Field CBR Test Plate bearing test Mackintosh probe test Dynamic cone penetration test Moisture content test Density test Specific gravity test Permeability test Liquid limit test. This is a light dynamic test and the cone is driven directly into the soil by driving a hammer 5kg.
The Mackintosh Probe is a lightweight and portable penetrometer. 1 CHAPTER 1 INTRODUCTION 1. 11 Advantages of Mackintosh Probe Fakher et al.
The vane shear test UU triaxial test and the unconfined When the Mackintosh Probe is used it is possible that a compression test with the Mackintosh Probe for com- value of M. Weight dropping through a free height of 280mm. Also make sure that the test holes are without roots of trees that can prevent devices from entering the ground.
Sand for LCM 61. Dynamic probing can have an important role in geotechnical site investigation. 1a experiment title mackintosh probe test date of experiment 31 st march.
The information obtained will be recorded and the results will be inserted into the report. Measure every 03m length of the steel rod and mark it with a chalk. JKR MACKINTOSH PROBE The Mackintosh Probe is a lightweight and portable penetrometer.
It took the steel cone 155 number of blows to reach the first 03 meter. Geotechnical Investigation Laboratory Testing Geotechnical Report Foundation Analysis and Design Geological and Geophysical Surveys Slope Stability Analysis and. This shows that the soil consistency is stiff.
DISCUSSION The mackintosh probe test was done until 21 meter depth of the soil. The purpose of recording is to identify the soil area that we examine. Capability and limitations of the Mackintosh Probe used for the study of engineering properties of recent soft deposits.
MackintoshJKR Probe Test This is a dynamic penetrometer test used to check the consistency of the subsoil. Faculty of engineering technology department of transportation engineering technology engineering technology geotechnic laboratory makmal teknologi kejuruteraan geoteknik experiment report course code and name bnt 20802 engineering laboratory ii experiment no. It is a considerably faster and cheaper tool than boring equipment especially when the depth of exploration is moderate and the soils under investigation are soft or loose.
The penetration steel cone took 85 number of blows at 09m which is more than the second depth of penetration which was 135 number of blows at 06m depth. The Mackintosh probe which has 30 cone penetrate while the JKR probe is 60 of cone. BETWEEN JKR PROBE AND MACKINTOSH PROBE.
A 25 mm diameter and 60 degree cone screwed onto the lower rod was driven into ground by a 45 kg. IT-LODGE-PORTAL TO Light light for investigation 70. In this study we used one set of 15 mm diameter series mackintosh probe with the length of 110 m each.
Count the number of blows that causes the rod to penetrate 03m. Use in difficult terrain where access is poor. Mackintosh Probe which has 30 0 cone penetrometer while JKR Probe has 60 0 cone penetrometer.
Mackintosh probe test is widely used to assess soil bearing capacity mainly on soft ground M-value. Results of JKR Probe and Mackintosh Probe can be taken as. Table 120 Result for the present Mackintosh Probe test 38 Table 121 Result for the NGMP 38.
This is a light dynamic test and the cone is driven directly to the ground driving a 5 kg hammer. Mackintosh Probe may be successfully used for soft The authors used the results of other tests including clays with undrained shear strength cu less than 50 kPa. This paper presents the capabilities of the.
In the test it is limited to a. Mackintosh probe test report discussion. Continue with the hammer blows and repeat the same work process.
Kuik Wall - Materials formulation 39. A 25 mm diameter and 60 degree cone screwed onto the lower rod was driven into ground by a 45 kg hammer falling freely through a height of.
