Abstract

This paper presents a summarized result of a foamed asphalt (FAM) design using 100 percent reclaimed asphalt pavement (RAP). Prior to beginning an FAM design, it is important to determine the optimum foaming conditions, specifically the expansion ratio (ER) and half-life (HL). In this study, several foaming variables were considered to find the optimum ER and HL values: asphalt temperature of 160, 170, and 180°C asphalt injection speed of 50 and 100 g/sec; and water content ranging from 1.0 to 4.0% in 0.5 increments. The FAM design was then proceeded with five trail asphalt contents (2.0 to 4.0% in 0.5 increments) to determine a single optimum asphalt content (OAC). Several conventional asphalt mixture performance indicators were utilized for the OAC determination including Marshall and retained Marshall stabilities, dry and wet indirect strengths, and tensile strength ratio.
