WILL GIVE THUMBS UP IF CORRECT AND FAST

a$)$ For emax $=0\mathrm{.}08,$ use the appropriate Table in the MTO Guide to determine the

minimum radius curve for a design speed of $90$ km$/$h$.$

b$)$ For a WB$-20$ design vehicle and a tangent pavement width of $7\mathrm{.}0$ m$,$

determine from the appropriate lecture slide table the amount of pavement

widening required for the minimum radius in Part a$).$

c$)$ Determine for the same conditions $($from the same table as Part b$))$ the

minimum radius for which no pavement widening is required $($the upper radius

limit for the minimum widening$).$

d$)$ For $\backslash$Delta $=45$ degrees, and assuming that no spirals are implemented, compute

the difference in pavement surface area between the two designs. Assume that

the widening is transitioned on the tangent over a length that is equivalent to the

required spiral length $($rounded up to the nearest $10$ m$).$

e$)$ Provide a short comment on your results.
