Correlation of fine aggregate imaging shape indices with asphalt mixture performance Masad, Eyad et al
Publication details: Transportation Research Record, 2001Description: nr 1757, s. 148-56Subject(s): Bibl.nr: VTI P8167:1757Location: Abstract: This study addresses the relationship between fine aggregate shape properties and the performance of hot-mix asphalt. Aggregate shape was expressed as three independent properties: form, angularity, and texture. Image analysis procedures and indices were developed to capture these properties. The indices were measured for 22 aggregate samples. The samples were related to the hot-mix asphalt rutting resistance measured under wet and dry conditions in the Purdue wheel-tracking device. Among the different aggregate shape properties, texture had the strongest correlation with rutting resistance. Resistance to rutting increased exponentially with an increase in aggregate texture.| Current library | Call number | Status | Date due | Barcode | |
