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)

By the Asphalt Institute method, determine the allowable ESAL for a 3.5-inch overlay on an asphalt pavement with a representative rebound deflection of 0.075 inches. E2 = (1.5x70x6.4)/0.062 = 10840 psi Deflection = 0.04621 ESAL = 347000
b) Define cutback asphalt. Among different types of cutback asphalt which one would you prefer to stabilize sandy soil and why?
Group 2 Q4: State whether the following statements are true or false: 1. Higher values of asphalt penetration test indicate softer consistency, and this asphalt is preferred for use in hot climate areas. 2. In AASHTO soil classification system, the group index (GI) is incorporated with the groups and subgroups of the soil to evaluate the type of a soil. 3. The asphalt material behaves more similar to a viscous fluid at intermediate temperatures and longer loading times. 4. Superpave performance grading (PG) considers the conditions under which asphalt is used while penetration and viscosity tests are not 5. Asphalt emulsions are classified into rapid, medium, and slow setting based on how quickly they revert to asphalt cement.
Please answer pricsely
1. During the AASHO road test, ONLY flexible pavements were constructed and tested.a. Trueb. False2. The AASHO present serviceability rating (PSR) was considered an objective quantity used to establish the performance of highway pavement in terms of applied traffic.a. Trueb. False3. The AASHTO present serviceability index (PSI) correlates the PSR to actual pavement performance in terms of applied traffic, and select distresses.a. Trueb. False4. There is only one AASHTO PSI equation that applies to both flexible and rigid pavements.a. Trueb. False5. The AASHTO PSI scale ranges from:a. 0-5b. 0-10c. 0-100d. None of the above
