Generally, the proposed PRDs can improve the confining pressure and hence is able to effectively improve the shear strength, bearing capacity, ability to resist elastic and plastic soil deformation, critical dynamic stress, and dynamic shear modulus of the embankment soil.
The temperature of soil surface in a depth of 5 cm and 10 cm at 9:00 am, 1:00 pm and 4:00 pm were changed in both of depth when cover with transparent plastic and in control treatment that is not covered by plastic soil temperatures in clay pots lower than the outside temperature.
In slope construction from mixed soil for increasing slope stability, employee of different types of soil with proper percentage is best option, in this regard 10 mixed soil types from red plastic soil and black, green, dark brown, yellow and light brown non plastic soils, sand, and two types of gravels 2 mm, 4.75 mm developed, and also from previous investigation (Table 1) safe bearing capacity, angle of friction, unit weight and cohesive of mixed soils sample for computerize model have been used, the Geo-Slope and origin software in calculation and identification of models behavior employed and the result of these research work by interpretation of mixed soil types characteristics and slope computerized model evaluated.
This group of do-it-yourself enthusiasts host "101s"--workshops on everything from how to sew a grocery sack from old plastic soil bags to raising your own chickens.
This system was designed to promote infiltration and store rainwater in the soil through the use of terracing, plastic soil covers, and other techniques.
For joining pipes to plastic water cisterns or to plastic soil pipes, some kind of hole cutter or hole-saw is essential.
Some very plastic soils are difficult to compact, and may shrink and swell when dried or when water is added.

Figure 7 implies that according to liquid limit, 57.2% of the studied fine-grained samples are low plastic soils (w} < 35%), 39.5% are medium plastic ([w.sub.l] = 35-90%), and 3.3% are highly plastic ([w.sub.l] = 50-70%).
However, it is in accordance with McBride and Bober (1989), who estimated the lower clay content limit for plastic soils with an OM of 0.1% at 4.8%.
