Generation of asphalt performance grading map for Egypt based on the SUPERPAVE™ program

This work aims to generate an asphalt performance grading map for Egypt based on the SUPERPAVE and LTTP programs. To achieve this aim, 60 weather stations data and air temperatures (maximum and minimum) recorded by Egyptian Meteorological Authority (EMA) collected covered of minimum 30 years of continuous temperature recording. The collected data and the calculated standard deviation were used to obtain surface and pavement temperatures for 21 representative stations for various climatic regions of Egypt. It revealed that four types of asphalt binder performance grades (at 98% reliability) are recommended for use in Egypt. The grades are PG 70-10, 76-10, 76-16 & 76-28.
