In an effort to improve mechanical properties of asphalt concrete, an exploratory research using mixture additives
was attempted. Two different types of additives on two material scales were used: asphalt concrete (AC) level and
binder level. At the start of this study, the effect of natural cornhusk fibers on the resistance of two types of AC
mixtures on cracking were tested for hot-mix asphalt (HMA) and cold-mix asphalt (CMA). The results showed slight improvements in cracking resistance in cornhusk reinforced HMA, and in the case of the CMA, marshal flow. Overall, based on the test results, cornhusk-reinforced HMA and CMA …
