文摘

Use of fine crumb rubber by dry process in porous asphalt. Drain-down test comparison between fine crumb rubber and fibres in porous asphalt. Higher bitumen/aggregate affinity of crumb rubber mixtures comparing to fibres mixtures. The use of crumb rubber improved the thermal and water sensitivity behaviour of porous asphalt. Higher ravelling resistance by means of Cantabro particle loss results for rubberized porous asphalt.
