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.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659185397\"\u003e\u003ch3\u003ePG 64-22 versus PG 64-28\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659185397","offer_id":39489939931229,"sku":"9783659185397","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5c04b434-4a9a-4be6-8b25-5ce8044de22f.jpg?v=1773381501","url":"https:\/\/shop.autorenwelt.de\/en\/products\/performance-comparison-of-asphalts-von-kwasi-adu-gyamfi","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
