Performance Comparison of Asphalts

PG 64-22 versus PG 64-28

• Broschiertes Buch

Produktbeschreibung

Eight test sections were constructed in Connecticut with PG 64-22 and PG 64-28 in 2006. In order to compare the performance of PG 64-22 and PG 64-28 asphalt, field performance data and laboratory parameters from these test sections have been statistically analyzed and compared. It was found that the field cracking, roughness and rutting performances of PG 64-22 and PG 64-28 sections on Route 59 were not statistically different. Similarly, tensile strength ratio and APA rutting measured in the laboratory on PG 64-22 and PG 64-28 materials from Route 59 were not statistically different. However, field cracking and roughness on Route 341 were different for PG 64-28 and PG 64-22 sections while the laboratory parameters were the same. It was also found that field cracking correlated weakly with laboratory parameters such as true low PG, TSR (%) and critical cracking temperature.
