(d)   Telford construction

(e)    Macadam surveyor construction

Different types of Roads

Chronological order of various Department →

→ Jayakar committee = 1927

→ Indian Road congress (I.R.C) = 1934

→ Motor vehicle act = 1939

TYPES OF ROAD PLANES IN INDIA

(1)   Nagpur road plan (1943 – 63) or first 20 years road plans.

(2)   Bombay road plans (1961 – 1981) or second 20 years road plans.

(3)   Lucknow Road plans (1981- 2001) or third 20 years road plans.

Nagpur Road plan (1943 – 63) or first 20-year Road plan

→ Duration = 1943 – 63

→ Road density = 16 km/100 km²

→ Road pattern = star and grid pattern

→ Development allowance = 15%

→ Road classification →

(i)     National highways (NH)

(ii)   State highways (SH)

(iii)  MDR (major district Road)

(iv)  ODR (Other district Road)

(v)    VR (Village road)

Bombay road plan (1961- 81) or second 20-year road plan

→ Duration = 1961 -81

→ Road density = 32 km/100 km²

→ Development allowance = 5%

→ Length of express ways = 1600 km

Lucknow road plan (1981 – 2001) or third 20-year road plan

→ Duration = 1981- 2001

→ Road density = 82 km/100 km²

→ Road pattern = Square grid

→ Length of express ways = 2000 km.

→ Road classification

(i)     Primary system or 1° system = Expressway, National highway

(ii)   Secondary system or 2° system = State highway, major district road

(iii)  Tertiary system or 3° system = Other district roads, village road.
