The laboratory result reveals that both fibres are effective in increasing the Marshall stability of the ordinary HMA. The coir fibre and kenaf fibre increases the Marshall stability of the ordinary HMA by 3.2% and 9.7% respectively. Therefore, coir fibre and kenaf fibre has potential in modifying asphalt. 引用文献 (18) 関連文献 (0) 図 (0) 著者関連情報 電子付録 (0)

The maximum stability of modified mix of coir is found 22.16 KN and the conventional mix is 18.06 KN which is 22.6% more than the conventional mix. The air voids are found to be decreasing with the increase in the fibre content. The air voids in the coir fibre mix is found be 8% less than the conventional mix.

Jan 01, 2020 Marshall test results for coir fiber modified asphalt mixtures. Three trial mixes were conducted using the blended aggregates, 6% asphalt and coir fiber of various percentages by weight of aggregate. A total of nine samples; 3 samples for each coir fiber percentage (0.2%, 0.4%, and 0.6% by weight of aggregate) were prepared.

This study demonstrates the properties of HMA mixed with coir fiber. The laboratory results reveal that coir fiber is effective in increasing the Marshall stability of ordinary HMA mixes. The coir fiber increases the Marshall stability of ordinary HMA by 41%. Consequently, coir fiber has promising potential in modifying asphalt mixtures.
