Title: EFFECT OF SEGREGATION ON PERFORMANCE OF HOT-MIX ASPHALT
Accession Number: 00646114
Record Type: Component
Availability: Find a library where document is available Abstract: Segregation of hot-mix asphalt has resulted in poor performance in many pavements. There is no procedure currently available for quantifying how much segregation is required to cause a reduction in pavement performance. Five pavements from Alabama were selected for a study to determine how much segregation can be tolerated before premature raveling is likely. Visual estimations of the severity of raveling and segregation were made and cores from the pavement were obtained. The density of the pavement was measured with a thin-lift nuclear gauge, and the macrotexture of the pavement surface in the segregated areas and the gradation of the cores were determined. The results showed that a variation in the percent passing the No. 4 sieve of greater than 8 to 10% can lead to raveling. A model was developed to predict raveling from the macrotexture and expected traffic.
