$2019$ year end supplementary

QUESTION $2$

Using the DCP chart and the table of DCP test results plot the DCP profile for the pavement

discussed.

A provincial road in the Midrand is currently being investigated to determine the most

appropriate long$-$term strategy. Major re$-$ alignment is due to take place in ten year's time,

which coincides with the termination of the original structural design period for the road. The

current traffic growth rate and traffic counts indicate that the road will experience $175000$ E$80\text{'}$s

per lane during its life.

Will the pavement is withstand the expected loading for the remaining life, assuming that a

reasonable level of serviceability must be maintained? Discuss your conclusion.
