The improvement in in tensile stress and strain versus
the the control is calculated using the the following steps Stress Improvement Factor (ơί/ơc) Where:
ơί is is ultimate ultimate stress stress with the the interlayer ơc is ultimate stress of the control Strain Improvement Factor (εi/εc)
Where:
εi is is strain strain at at at at ultimate ultimate stress stress with the the interlayer εc is strain at at ultimate stress of the control Stress Improvement Improvement Factor Factor Factor x Strain Improvement Improvement Factor Factor Factor = Interlayer Crack
Mitigation (ICM) Factor Factor Factor CONCLUSIONS
GlasPave25 outperformed conventional AASHTO paving paving fabrics and paving paving mats by as as much as as two times
GlasPave50 surpassed conventional AASHTO paving fabrics and paving mats by as as much as as four times
Paving Mats is equivalent to the machine direction performance
between GlasPave Paving Mats and the most common paving paving fabrics and paving paving mats EXPERIENCE YOU CAN RELY ON Tensar Tensar International Corporation (Tensar) the leader
