Tie bars are used across longitudinal joints (warping joints). They are not used a load transferring devices. Tie bars are thus designed to with stand tensile stresses, and the maximum tensile force in tie bars being equal to the force required to overcome frictional force between the bottom of the adjoining pavement slab and the soil sub-grade. Dowei bars are provided at expansion and contraction joints and they act as load transferring devices.

Explanation:
Tie bars are used in the design of modern concrete pavements to provide load transfer across joints. They are typically made of deformed steel bars and are placed across the joint between adjacent concrete slabs. The use of tie bars helps to distribute the load from one slab to the next, which helps to prevent cracking and other forms of damage.
In modern concrete pavement design, tie bars are typically used in contraction joints. Contraction joints are used to control cracking in concrete slabs due to shrinkage as the concrete cures and dries. Without contraction joints, the concrete would crack randomly, which would compromise the strength and durability of the pavement. By placing tie bars across the contraction joints, the load is transferred between adjacent slabs, which helps to prevent cracking and damage.
Tie bars are not typically used in expansion joints or warping joints. Expansion joints are used to provide room for the concrete to expand and contract due to temperature changes. Warping joints are used to accommodate the natural movement of the concrete due to the contraction and expansion of the pavement. In both cases, tie bars are not necessary, as the joints are designed to allow for movement without compromising the integrity of the pavement.
Therefore, the correct answer is option B: tie bars are used as load transfer devices in contraction joints.
