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)
