Consider the following Statement:
P) Tie bars are installed in warping joints in cement concrete pavement.
Q) Radius of the relative stiffness of cement concrete pavement depends on wheel loads.
R) Base course is used in rigid pavements for prevention for pumping
T) Dowels bars are provided at expansion joints and sometimes also at contraction joints in cement concrete pavement.
For the above statement, the correct option is
1
P → False, Q → False, R → False, S → True
2
P → True, Q → False, R → True, S → False
3
P → False, Q → False, R → True, S → True
4
P → True, Q → False, R → False, S → True
