Rectification of Rigid Pavement Why we provide approach slab Crust thickness details of each project Wearing courses in detail

Question

Accepted Answer

Approach slabs are provided for rectification of rigid pavement to ensure smooth transition and prevent damage to the pavement.

Approach slabs are used to provide a smooth transition between the rigid pavement and the adjacent flexible pavement.
They also help to distribute the load from the flexible pavement to the rigid pavement.
Crust thickness details vary for each project depending on factors such as traffic volume, climate, and soil conditions.
Wearing courses are the top layer of the pavement and are designed to resist wear and tear from traffic.
They are typically made of asphalt concrete or concrete and can vary in thickness depending on the expected traffic volume.
