Nowadays, roller concrete reinforcement has been considered by researchers to reduce maintenance costs and increase the lifespan of the pavement. In this paper, we will examine the performance of the glass fiber against cracking lengths of 12 and 24 mm. In this study, to compare the mechanical properties, the percentage of fibers used in the samples is constant, but the length of the samples varies.
By uniformly distributing the fibers, glass reinforced concrete with a length of 12mm has a higher compressive strength than the non-reinforced concrete but weaker performance in tensile strength. Also, glass reinforced concrete with a length of 24 mm exhibit better performance in the tensile and compressive test against the other two samples.
In the bending test, it was observed that the non-reinforced concrete cause an instantaneous rupture, and in the sample containing 12 mm fiber a small amount bridging phenomenon evident.
A small amount is evident.
It can be said that the results of the bending test of the non-fiber specimen with the specimen containing longer length fibers (24 mm) are close.
