Asphalt Mix Design And Performance, Shakor Ramat Badaruddin, Thomas D. White

JTRP Technical Reports

Premature flexible pavement distress became a major concern in Indiana. As a result, a study was conducted investigating the major underlying factors. Pavement sections were investigated based on a factorial study with four factors comprised of climate, truck traffic, pavement base type, and wheel path. The distresses evaluated were rutting, thermal cracking and stripping. All were evaluated against control sections with zero distress. The pavement condition of each section was determined. Laboratory tests of field sample included physical properties, dynamic creep and recompaction. Results of the study indicate that the Asphalt Institute mix design criteria identify an asphalt content that …
