Figures & Tables

Figure 1

Longitudinal crack in the surface as a result of uneven settlement of the embankment.

Figure 2

Measurement results of settlement of the embankment (in the axis, on the left and right edges of the roadway).

Figure 3a

Expressway S-8 Wrocław-Syców, cross-section at km 14 + 630 – embankment placed directly on the layer of silts (stability assessment performed according to [21]).

Figure 3b

Expressway S-8 Wrocław-Syców, cross-section at km 14+630 -replacement of the layer of silts.

Figure 4

Dependence of limit resistance to shearing τf of the ash-sand mixtures, depending on the embankment height[1].

Figure 5

Embankment with the height of 12 m, made of ash-sand mixture.

Figure 6

Safe slope gradient of the road embankment formed from ash-sand mixtures in the function of embankment height - results obtained for the factor of safety Fmin = 1.5 [1].

Figure 7

Change in the angle of internal friction ϕ, depending on the composition of the mixture.

Figure 8

Change in the cohesion c, depending on the composition of the mixture.

Figure 9

Change in the maximum bulk density of the skeleton, depending on the composition of the mixture.
