Pavement Temperature
Interested postgraduates at the department of Civil Engineering, University of Al-Fateh are invited to register in an MSc research study under the title of: Measuing the Pavement Temperature in Libya. The research is sponsored by NESCO and is ready to be lunched as soon as possible. Please e-mail or call in at my office.

Salam,
What on earth would it be useful to measure pavement temperatures in Tripoli??????
To clarify Safia’s wonder, Do you know that pavement temperature in Libya (particularly in the middle and south regions)could be double the air temperature. i.e. If Air temperature is 45 C then pavement temperatures might be 85 C. This has a significant effect on the performance of highway pavements in those regions. The rapid hardening and aging of asphalt binder is the main cause of pavement cracking. It takes place due to the evaporation and oxidation of the volatile components of asphalt due to high temperatures. The other important factor is the generated thermal stresses due to drop of temperature during the diurnal temp. cycle. What are we trying to do is to measure the actual temperature in a real pavement subjected to the environmental factors (Temp., solar radiation, wind, ..etc.) and to develop a model that could be used in predicting the pavement temperature regimes. This will enable engineers to select the appropriate asphalt for the project based on performance.
