The study investigated the performance of three duckfoot tools, A105, B135 and C200, corresponding to the tool widths of 105, 133 and 202 mm, respectively. The tools were connected with two flexible tines; flexible S-tine and stiff VCO-tine of stiffness 5.3 and 8.3kNm−1 and clearance tool angle setting of 8° and 2°, respectively. Experiments were carried out in a soil bin filled with fine loamy soil...
The aim of the paper was studying the resistance during splicing of soil, represented by the horizontal resistance component (Fx), depending on changes of speed and working depth of a work piece in form of a duckfoot share. The study was realized under laboratory conditions in a soil channel which ensured repeatability of results. The tested work piece was a duckfoot share with width of 135 mm installed...
Design of road pavement is connected with estimation of mechanical properties of each of the materials used for construction. This statement presents the need of estimating the mechanical moduli. For the purposes of this article, tests were carried out in order to establish physical and mechanical properties, especially penetrating resistance CBR. The main aim of this paper was to estimate the optimal...
Process of chemical stabilization of cohesive soils infl uences its mechanical properties, also in the case of soil cohesion. Road constructions consist of few layers which have various mechanical properties and this creates the need for better understanding the impact of chemical stabilization on soil as a layer of road. For the purposes of this article, tests were carried out in order to establish...
