| Summary: | Deformation of the road was the main factor of the repeated loaded at
high temperature to the asphalt pavements and one of the main distress
mechanisms. Asphalt mixture incorporated with steel fiber to enhance
the tensile strength would have investigated by used grade 60/70 of
asphalt binder and 5% of optimum asphalt binder. The percentages of
steel fiber that were used for the studied was 0, 1.2, 1.5, 2.1, 2.4% by
total weight of aggregate. Purpose of this studied is to investigate the
effect of steel fiber toward the asphalt mixture on improved the asphalt
pavement. To decrease the road deformation and to compute the
pavement cracked at incorporating steel fiber using Marshall Stability
Test. The result from this study has shown that the mixture
incorporating steel fibers for stability is decrease between control
sample with 2.7% steel fiber which is 21.357 kN and 13.193 kN. The
performance test due to stiffness analysis passed the requirement JKR,
which is more than 2.6 kN/mm, even if the value of the steel fiber
modified sample is lower than the control sample and it still relevance
to implement |
