Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

Plz, solve this proboem. Transportation Engineering-2 Estimate what standard PG asphalt binder grade should be selected if the seven-day maximum pavement temperature has a mean of 680 C and a standard deviation of 2.50 C. The minimum pavement temperature has a mean of -220 C and a standard deviation of 30 C. Use a Reliability level of 99 %. Note: seven-day maximum and minimum pavement temperatures are normally distributed (use cumulative standard normal distribution tables)

Which is better in terms of maintenance and usability flexible pavement? concrete pavement? concrete pavement with top layer of flexible pavement? explain your answer
The traffic on the design lane of a proposed four-lane rural interstate highway consists of 40% trucks. If classification studies have shown that the truck factor can be taken as 0.45, design a suitable flexible pavement using the 1993 AASHTO procedure if the AADT on the design lane during the first year of operation is 1000, pi=4.2 and pt=2.5. Growth rate= 4% Design life= 20 years Reliabilitylevel= 90% Standard deviation= 0.45 The pavement will be exposed to moisture levels approaching saturation 20% of the time, and will take about one week for drainage of water. Effective CBR of the subgrade material is 7. CBR of the base and subbase are 70 and 22, respectively, and Mr for the asphalt mixture, 450kips/in2.
