Rubber Products by Calendering



Calendering consiss of a number of rolls held in a frame work. It is an expensive piecce of equipment containing usually three rolls and products sheet with smooth surface and accurately controlled uniform thickness. The rolls are therefore carefully ground and top and bottom ones are adjustable. Vertically related to the center fixed roll. So that the thickness if the sheet can be varied. Calendering machine used in rubber industries are 3 ot 4 roll calender.

In the case of three roll calender usually t ....etc

SKID RESISTANCE ON PAVEMENTS


INTRODUCTION
Road engineers & users are concerned with the safe passage of vehicles that operate over them.
Safety on road is assessed by its skid resistance.
Slippery pavements are known to be the cause of many road accidents and fatalities.
Skid resistance involves the complex interaction of pavement , vehicle and environment factors.


SKID RESISTANCE
Skidding is the jerking of the wheels of the vehicles when it locked due to the sudden breaking , if the frictional ....etc

RUBBER TYRED METRO


INTRODUCTION
A Rubber-tyred metro is a form of rapid transit system that uses a mix of road and rail technology.
In this the vehicles have wheels with rubber tyres like a bus, but using a set of two parallel concrete or corrugated steel rollways, each with the width of a tyre.
The vehicles have wheels with rubber tyres which run inside a guide way for traction, as well as traditional railway steel wheels with flanges on steel tracks for guidance.

IMPROVEMENT OF MECHANICAL PROPERTIES OF RIGID PAVEMENTS

INTRODUCTION
Transportation-basic infrastructure-development

Rigid and flexible

Basic neccesity-stable against loads

Rigid offers more strength “load

But change in temp. “warping up and warping down

To relieve stress-joint

Joint from the weaker plane and most of defects occur there

Increase the mechanical properties such as load carrying capacity and cracking resistance

Methods for improvement
