FORTA-FI Makes the Grade in Reflective Crack Resistance

Four laboratory tests were used to determine the cracking resistance of a control SMA and a SMA modified with FORTA-FI.  The tests estimated a Flexibility Index (FI), critical strain energy release rate (Jc), Cracking Test index 9 (CTindex), and Cracking Propagation Rate (CPR). 

Overall, results from the four tests conducted indicate that the fiber-modified SMA mix has a higher resistance to cracking compared to the control SMA mix.
