The design of Concrete Pavement
The performance of a concrete pavement for traffic riding purposes depends not only upon the property of materials but also on the underlying sub-grade or the base course. The design of a concrete pavement must involve all physical properties of concrete. Concrete withstands high compression but it is low in tension (flexure). Like wood, it expands on wetting and shrinks while drying. With temperature, like other materials, it decreases or increases in length. Under some conditions its volume increases with age. A concrete pavement when subjected to variations of daily temperature and moisture between the top and the bottom of the slab will have a tendency to warp and curl.
The following conclusions have been generally established after a series of theoretical approaches and practical results in concrete pavement design:
1.Cracking due to flexure is almost inevitable in a concrete slab of any great length.
2.For constant loads on slabs of reasonable length, load and total stress decrease as slab thickness increases, that is to say, if the safe working stress were to remain the same, the slab thickness must increase as wheel loads increase.
Reinforcement. The provision of reinforcement in a concrete pavement is designed to hold cracks that develop due to flexural stresses as close as possible, so that they may not develop into a major defect. It must be remembered that reinforcement is not used either to increase the load bearing capacity or for complete prevention of cracking. Reinforcement may be used: 1. To prevent fracture surface from widening and to tie all parts of the slab together. 2. Where there is a possibility for the sub-grade to become weak and non-uniform in bearing, so that the induced cracks may not get widened and exposed to action of dirt and water. If additional load bearing capacity is required this can be easily achieved by thickening the pavement.

Hi, my dear friend! How are you?How did you spend your summer vacation? ? And I carried out them most productively and it is useful. I not simply for days on end sat at the computer, the TV, went simply to the street. I helped the parents about the house. I asked them to give me a task and I carried out it diligently. In the middle of the summer I spent summer vacation in the countryside. There very much it was pleasant to me. Fresh air, beauty of the wood, warm water of the lake. There I got acquainted and made friends with boys and girls. There it was very interesting as every day it was filled a set of events. In the afternoon we went to the lake, to the wood, gathered mushrooms. In the evening we watched animated films or movies, danced in discos. This summer very much it was pleasant to me as I spent summer vacation. I think that academic year will be interesting, and I too will try to spend it it is useful for itself and surrounding me people.  But during this time I very much missed you, I wait for your answer rather.

The world has not been the same as we know it today. Humanity has come a long historical way since the Stone Age. And choosing the most important events in world history is one of the most difficult and controversial task. 
Perhaps the most important thing that happened to the world was the Second World War. It was the largest and deadliest war in human history. We should be aware of horror and destruction the war can bring. And we should do all our best to save our society from повторення such a terrible event.
The second world war lasted 6 years, swept almost all continents. It was attended by over 60 countries
It goes without saying that there are pros and cons of each war. Let's start from the negative impacts.
The negative effects of war are, of course, death and destruction.  Millions of people have died in such a big wars like WWII.  Cities can be devastated, hurting a country’s economy.  These things cause terrible human misery.
There are, however, also possible positive effects of war.  War can correct terrible injustices.  For example, the US Civil War caused an end to slavery in that country.
Wars can also lead to technological advances that help society.  One instance of this is the development of air travel after WWII, which was strongly influenced by the wartime development of large, long-range bombers.   
War accelerates both technological and medical advances because all sides are attempting to invent better ways of killing and better methods of preserving the lives of combatants, and some of these advances benefit the civilian populations, assuming they survive the war.
It is reasonable to conclude that all wars are bad, but, in rare cases, war is forced upon the participants by the actions of one or all parties.  It is also reasonable to believe that the negative effects of war, in all cases, far exceed the potential benefits.  The fact is, there are no good wars.  There are only wars that are less bad than others.
