| 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. The repeated load indirect tensile tests at three different
temperatures (30°C, 40°C, 50°C) and five different dynamic loadings (500N, 750N,
1000N, 1250N, 1500N) were carried out under stress controlled mode using the MATTA
Machine. The fatigue performance test results plotted on a logarithmic scale of fatigue
strain and load repetitions showed a good agreement with the historic trend of the
fatigue data. The logarithmic relationship between fatigue loading and strain was
evaluated and found to be linear at certain reliability regardless of the testing condition
and mix parameter. This indicates that the fatigue model for SMA is a function of asphalt
volume, resilient modulus and the fatigue strain values. |
