Stiffness evaluation of Forta Fibre Reinforced Asphalt Concrete (FRAC) mixture under different pulse repetition load

Abstract Pavement structure can be designed either as a flexible or rigid pavement based on its structural behaviour, with pavements being frequently favored due to advantages. One of the major problems that normally occurred in road construction was distresses quality materials. Numerous studies were carried out explore sustainable ways improve performance especially modification asphaltic concrete phases. This paper investigates effect Forta-Fi fiber stiffness hot mix asphalt mixture (HMA). In this respect, conventional binder grade 60/70 and Nominal Maximum Aggregate Size (NMAS) 12.5mm used preparation specimens specified Superpave design method. Performance modified samples incorporating 0.3, 0.5 0.7% total evaluated for resilient modulus accordance ASTM D4123 using Universal Testing Machine (UTM). The tested at 25°C 40°C pulse repetition period 1000ms, 2000ms 3000ms simulate low, medium high volume traffic. As result, values improved 38% 0.3% additive period, while 23% 0.5% Forta-Fi. Based these studies, addition fibers reinforcement into has significant reinforced mixture.
