Fatigue Modelling for Stone Mastic Asphalt (SMA)

Fatigue cracking is one of the major distresses found in many asphalt pavements. The premature cracking of the pavements results in the increased annual cost of resurfacing, maintenance and rehabilitation. Generally, any asphalt mix is tested in the laboratory and predictions are made using the p...

description Fatigue cracking is one of the major distresses found in many asphalt pavements. The premature cracking of the pavements results in the increased annual cost of resurfacing, maintenance and rehabilitation. Generally, any asphalt mix is tested in the laboratory and predictions are made using the performance curves and local conditions. However, in Malaysia there are not any pavement prediction models developed yet that can be used to predict the asphalt mix's fatigue life performance under the local environmental conditions. This paper looks into the fatigue characteristics of SMA by using local materials and environmental conditions. For the purpose of evaluation SMA14 ( SMA with 14mm aggegate as nominal) with 5 different gradations within the JKR's ACW14 gradation envelope were used.
