Focusing on the safety of your crew does not just mean fewer injuries; it also makes financial sense. That’s why we adhere to the motto: “Safety isn’t expensive, its priceless!” Yes, next to the standard PPE hat drillers and assistants need to wear, there are also standards for safety for machinery used in the drilling industry. But our machines are designed to be even ...
Introduction Cone selection is often not given much thought when selecting equipment for a Cone Penetration Testing (CPT) job. It is, however, quite important to consider the soil type that will be encountered as well as the investigation aims of the project. The CPT cone used can have huge impacts on the resulting data quality and applicability and should therefore be carefully considered. This ...
Two of the common methods to measure firmness are the application of pressure and the deformation of the fruit. Penetrometers Some of the Penetrometers on the market which measure firmness are: Magness-Taylor’s Pressure Tester, based on a punch test. ...

From this, a subset was selected and 30 manual cone penetrometer tests were conducted at full latrines. Chemical oxygen demand analysis was also performed for 14 pit latrines. ...
Road conditions were monitored before and after the successful reconstruction of the road using the dynamic cone penetrometer, nuclear densometer, Atterburgs Limit testing, and soil Proctor analysis. ...
Once appropriate materials were obtained, the road was reconstructed using a mix of 32% clay and Road conditions were monitored before and after the successful reconstruction of the road using the dynamic cone penetrometer, nuclear densometer, Atterburgs Limit testing, and soil Proctor analysis. ...
Other data collected in the test sections included rut depth and Dynamic Cone Penetrometer measurements. Practices recommended to improve flexible pavement performance include: implement SHRP specifications for designing AC surface and intermediate mixes with PG grade asphalt cement, polymers and smaller midrange aggregate; construct uniform stiff subgrades; and maximise ...
Guidelines are summarized for interpreting in situ test data, particularly for estimating intact and remoulded undrained shear strengths from the penetration resistance measured by each type of penetrometer. Suggestions are also given for future development of in situ testing techniques to maximize the potential of in situ testing in characterization of deepwater soft ...
Extractable P and K, pH, soil organic matter (SOM), active C, water-stable aggregates, bulk density, penetrometer resistance, and microbial biomass/diversity were measured, and the Soil Management Assessment Framework (SMAF) soil quality index (SQI) was determined. ...
As part of this design, Black & Veatch performed cone penetrometer testing, collected and analyzed geotechnical samples, and mapped out the site’s existing low permeability layer to identify the optimal alignment and key-in depth of the barrier. ...
So-called hydraulic 'push' technologies (e.g. cone penetrometer, Geoprobe®,, QED HydroPunch®,) enable relatively fast screening site characterization which can then be used to design and install a monitoring well network. ...
This paper describes the theory and the laboratory test results for determination of the density of a sand with a quasi-static penetrometer by measuring its thermal conductivity. Effects of disturbance caused by the penetrometer have been studied. It is shown that it is possible to obtain the density of sand by precalibrating the ...
The appropriate assumption depends on the nature of the testing mechanisms as demonstrated in this paper by three examples involving testing with the dynamic cone penetrometer. Finally, it should be mentioned that the nonnormally distributed case is very frequent, especially when the pool of results includes tests performed on different types of soils, even when the results of ...
Liquid and plastic limits tests are, in fact, performed in the PRC using a special laboratory fall cone penetrometer apparatus. An experimental study was made to compare Atterberg limits determined for low plasticity artificial soil mixtures and a limited number of split spoon samples using U.S. and PRC standard procedures. ...
A dynamic penetrometer was designed for the purpose of evaluating compaction quality in fills constructed with boiler slag. ...
A small diameter piston sampler that can be operated by a cone penetrometer rig has been developed specifically for recovery of sand and clay samples under conditions where sample recovery using ordinary means is difficult. ...
The design and operation of a conceptually simple, low-cost chamber for calibration of cone penetrometers and other in situ devices is described. The chamber weighs over 5500 kg and houses a 4400-kg soil sample that is 1.5 m in diameter and height. ...
Small vane and penetrometer devices have been developed to measure soil properties in models during centrifuge operation. ...
A flat-plate penetrometer, similar to the flat-dilatometer, has been constructed and used in a series of laboratory experiments to estimate the shear modulus of cohesionless soils under repetitive loading conditions. ...
