Temperature has a large effect on the asphalt viscosity. Plot a typical (qualitative) relationship between asphalt viscosity (logarithmic) and temperature for two cases: (a) a low-temperature susceptible asphalt and (b) a high-temperature susceptible asphalt.
Binder grade of asphalt selected for a highway construction based on the temperature recordsfound to be PG70-16. Answer to the following questions:• If traffic speed is high (more than 70 km/h) and 0.2 million ESAL, what is your suggestionfor the binder grade?• If traffic speed is slow (less than 20km/h) and traffic volume is very high (40 million EASL), what is your suggestion for the binder grade?
Temperature has a large effect on the asphalt viscosity. On one graph, plot the relationship between asphalt viscosity (logarithmic) and temperature for two cases: (a) a low-temperature susceptible asphalt and (b) a high-temperature susceptible asphalt. Label all axes and relations.
