Question

What is the approximate super-elevation rate for a curve with a 2,000ft radius on highway with a design speed of 65mph? The maximum design super-elevation is 6% for this highway. a) b) c) Please determine the approximate super-elevation rate If max design super-elevation is 6%, does it meet the requirement? (yes/no) PLEASE SHOW ALL STEPS AND EXPLAIN. THANKS
