In court cases regarding playground surfacing, the National Center on Accessibility has investigated surfaces using the Rotational Penetrometer
to convey the presence or lack of firmness and stability.
Instead the ball penetrometer
and shaft are suspended from a load cell inside the machine.
For measuring soil horizontal resistance a horizontal penetrometer
was used (Fig.
Procedure: Apply sufficient pressure to allow the penetrometer
to move slowly into the mold surface.
A total of 397 study points were obtained including 35 penetrometer
Cotching and Belbin (2007) found that there was a well defined relationship between penetrometer
resistance and soil water content, especially at 0.
This method is specifically indicated for research related to stepwedge penetrometer
SGS Manufacturing has published a two-page flyer spotlighting its new recording dynamic cone penetrometer
The CP-1000 is a cone penetrometer
, a tool that can go deep below the surface to collect data that characterizes the soil.
When using a penetrometer
, soil strength is described by cone index (CI), the ratio of the force required to push the penetrometer
into the soil to the base area of the cone.
(CPTu) soundings, direct push samples, wire-line samples, and hand augers were done at various locations to determine the material content of BR2.
Rind strength can easily be measured as the force required to puncture the rind with a needle with a rind penetrometer
