What is the ruling radius of a horizontal curve?
Dhanya
The maximum comfortable speed on a horizontal curve depends on the radius of the curve. It is possible to design with maximum superelevation and coefficient of friction. If the design speed is increased in the future. So the radius of the curve is not desirable. Therefore a ruling minimum radius canRead more
The maximum comfortable speed on a horizontal curve depends on the radius of the curve. It is possible to design with maximum superelevation and coefficient of friction. If the design speed is increased in the future. So the radius of the curve is not desirable. Therefore a ruling minimum radius can be derived by assuming maximum superelevation and coefficient of friction.
Ruling Radius = v^2/g(e+f)
Generally, the radius of the curve is higher than the ruling radius

It is the by product of iron extraction process from iron ore.
It is produced as the by product of electric arc furnaces in the production of elemental silica.
Rice Husk Ash is produced by the burning of rice husk.
ordinary clay and kaoline clay when thermally activated is called metakaoline

Dhanya
The freshly quarried stones contain some amount of moisture. This is called quarry sap. The process of removing quarry sap is known as seasoning of stones. Generally 6 to 8 months required for proper seasoning.

Indian Patent Flooring (IPS) is a normal type of concrete flooring.
Construction procedure:
- Make reference level on the wall. It is transferred across all the floor area.
- Flooring thickness to be marked and also dummy level dots should be provided in every 1 to 2m
- After proper setting, concrete of desired mix should be poured in panels to minimize shrinkage cracks.
- After pouring level the surface with trowel.
- Allow it to harden for about 36 hours
- For gloosy and smooth IPS flooring, neat cement pinning, 2 to 3 mm thick is spread over the concrete surface and allowed to soak.
- For curing of IPS flooring surface pond or wet Hessian cloths are spread over the surface for 15 days.
