Introduction

Pavement shoulders, though they are not intended to carry traffic directly, serves a number of purposes to the pavement, such as (Chakroborty and Das 2003):

•  Prevents intrusion of water to the pavement layers.

•  The shoulder is sometimes used as foot-path, or bikeway.

•  The shoulder carries traffic in special situations, and gives psychological comfort to the drivers, and sometimes accommodate vehicle parking.

•  When construction activity is going on the main carriageway, shoulder may be used as temporary driving lanes.

A design traffic of 2-2.5% of the main carriageway traffic is generally used for design of concrete pavement shoulders (Ababio-Owusu et al. 2003). In this lecture, different types of shoulders of the concrete pavement are briefly introduced.
