Characterisation of Laboratory and Field Foamed Bitumen Stabilised Beams from Accelerated Pavement Testing Trial
The purpose of this study was to compare the properties of field constructed and laboratory manufactured foamed bitumen stabilised (FBS) beams under different conditions. A full-scale outdoor test pavement section was constructed with in-situ foamed bitumen stabilisation equipment at the accelerated loading facility (ALF) in Dandenong. The field beam specimens were cut from FBS slabs extracted from the trial pavement test section and the laboratory beams were manufactured in a mould using a British pendulum compactor. The flexural modulus of the field extracted beam specimens and laboratory manufactured beams were investigated using a four-point bending apparatus under different test conditions. Also, X-ray CT scanning was conducted on some field and laboratory samples to study the bitumen distribution throughout the aggregate skeleton. Flexural modulus master curves were developed for laboratory manufactured and field extracted beam specimens. Field extracted beam samples showed lower sensitivity to temperature and frequency compared to the laboratory manufactured FBS specimens.
