Bias tires are also generally easier to repair than radials and, because of the sheer amount of layers, offer the most penetration resistance
in the sidewall.
Soil penetration resistance
was measured at field capacity using an Eijkelkamp penetrologger (Eijkelkamp, Giesbeek, The Netherlands) during September 2012.
The size of the water penetration section depends on the water pressure and the penetration resistance
which is mainly affected by the melt temperature, mold temperature, water delay time, and cavity section [25,32-35].
Similarly, the undrained shear strength of marine clay at South Pars field in Iran was evaluated using cone penetration resistance
by Ebrahimian et al.
The total number of strikes was counted to 10 cm interval depth and the soil penetration resistance
was calculated by the following formula:
A mortar-setting-time tester was used to measure the pressure values of the expandable slurries with high water content over time, and the pressure values obtained were substituted into the following equation to calculate the penetration resistance
of the slurries over time :
Also, the waterproofness of concrete containing fine particles of blast furnace slag improves as the generated calcium-silicate-hydrate (C-S-H) gel improves the pore system and subsequently the sulfate and chloride ion penetration resistance
Hasan (2012) found increment in penetration resistance
, due to traffic, of 100, 51 and 15% at depths of 10, 20 and 30 cm, respectively, and indicated moldboard plow as the most efficient implement to reduce penetration resistance
in the studied soil.
Soil mechanical penetration resistance
was measured on August 27, 2013.
The reduction of soil pores occurs with the traffic of machines due to the pressures applied by the wheels and consequently increases soil penetration resistance
