Durafil is designed to enhance the performance of asphalt pavements. Durafil offers asphalt pavement technologists options to select from a wide range of custom blends to optimise their pavement design parameters. Custom blends are produced by blending hydrated lime and black coal fly ash in nominated proportions at the Independent Cement and Lime (ICL) state-of-the-art blending facility in Yarraville, Victoria. Durafil is a premium quality HMA filler that conforms to both Industry Standards VicRoads 407.04 and AS 2150. ICL selects and tests both the materials used in Durafil and the final product, in accordance with Australian standards and guidelines.
