                                                          IRC classifies the network of roads in india into following categories

1) National highways ( NH )

2) State Highway ( SH )

3) Major District Roads ( MDR )

4) Others District Roads ( ODR )

5) Village Roads ( VR ) 

1) National highways 

                                        National highways were defined as the important roads running through the length and breadth of India connecting ports capital cities, foreign Highway, industrial centre and strategic point . National highways should have 2 lanes of traffic and should be 7.50 m wide . It should be necessary a bituminous or concrete road giving an uninterrupted road communication throughout India and should connect the entire road network . All the national highway are assigned the respective numbers. 


2) State Highway ( SH ) 

                                           State Highway were defined as the main trunk or areterial roadsof a State connecting national highway of adjacent states, district headquarters and important towns within the State. State Highway should preferably be 7.50 m wide and where it is only 3.80 m wide it should have 2.0 m wide graval shoulder on each side to support the carriage way. Milestones in case of State Highway are painted in green top and white base. They are also of bituminous material or cement concrete type roads.


3) Major District Roads ( MDR ) 

                                                         The important district roads which connects district headquarters production and markets center with either a State Highway or a railway station are termed as major district roads.

 

4) Others District Roads (ODR )

                                                     The roads within a district which connect rural areas of production with market , educational center and major district roads are termed as other districts roads. They are mostly meant for serving population living in rural areas. These roads have single lane width of atleast 3.8 m of stablosed soil or compacted gravel . 


5) Village Roads ( VR )

                                        The roads connecting village of group of village with each other and to the nearest district roads or railway centres are termed as village roads. As these are village arteries they should not be neglected but must be planned well to form a regulated system of transportation. They are basically farm tracks or earthen roads serving rural population .

Grade of concrete                                   Grade of concrete is defined as the minimum strength the concrete must possess after 28 days of construction with proper quality control. Concrete grade Grade                  Proportion  M 5.                      1: 5 : 10          M7.5.                    1 : 4 : 8        M10                      1 : 3 : 6    M15.                    1 : 2 : 4    M20.                    1 : 1.5 : 3    M25.                    1 : 1 : 2    M30                      1 : 0.75 : 1.5

10 class math airthmatic progessions excerise 5.1

-
Excerise no 5.1 1) In which of the following situations, does the list of number involved makes as airthmatic progessions and why ?   A) the taxi fare after each km when the fare is RS 15 for the first km and RS 8 for each additional km  Answer    It can be observed that  Taxi fare for 1st km = 15   Taxi fare for first 2nd km = 15+8 = 23 taki fare for first 3rd km  = 23+8 = 31 Taki fare for first 4 km    =31+8 = 39 Clearly 15, 23, 31, 39 form an A.P. because every term is 8 more than preceding term. B) the amount of air present in the cylinder when a vaccum pump remove 1/4 À of the air remaining in the cylinder at a time Answer  Let the initial volume of air in a cylinder by V litres . In each stock the vaccum pump remove À 1/4 À of air remaining in the cylinder at a time . In other words after every Stoke only 1- 1/4 = 3/4 Part of air will remain Therefore volume will be V, 3V/4 , (3V/4 )², (3V/4 )³.... Clearly it can be observed tha

Spread Foundation or open Foundation The Foundation which is constructed over a large area to form a wide base over which the whole structure rests is called spread or open Foundation. These Foundations are made with increasing the base by making off sets. It is a type of shallow Foundation. this type of Foundation is constructed in open excavation by increasing the area at the base of structure by means of offsets or batter. This is most common type of Foundation and is practicable for a depth of about 5 m and is generally convenient above the water table. This Foundation is provided for bridges of moderate height built on sufficiently firm dry ground. If the ground is not stiff the bearing surface is further extended by wide layers of line concrete at the bottom. Method of construction                                             Excavate the Foundation trench to the exact width and to the designed depth. the bottom is well rammed and then Foundation lime concrete in layers
