Potential advantages of recycling asphaltic concrete with natural rubber
Aggregates suitable for road mixes are scarce and expensive in kuwait. The recycling of asphaltic mixes is therefore an attractive proposition. The road research centre, roads administration, ministry of public works, kuwait, has carried out laboratory studies to determine the suitability of existing asphaltic concrete for recycling, the resultant properties of materials and effects of adding natural rubber to the recycling mix with a view to establishing suitable mix design criteria, applicable over a wide range of environmental and traffic conditions. Most of the work is performed in the temperature range 7-60 degrees celsius, the typical road surface temperatures experienced in kuwait as well as in other countries of the arabian gulf and the tropics. The amount of rubber used is only one part per thousand parts of asphaltic concrete. The results on rutting, creep, fatigue, mix stiffness modulus and stability are quantified and the improvements with natural rubber are illustrated. The properties of the mixes using 50 per cent recycled asphaltic concrete with rubber, are found to be significantly better than recycled asphaltic concrete mixes without rubber (a).
