The required minimum characteristic design concrete flexural strength for concrete pavements with a design traffic of 10 HVAG or more is 4.5 MPa at 28 days, except for steel fibre-reinforced concrete, where the requirement is 5.5 MPa. 

The use of steel fibre-reinforced concrete does not affect the amount of reinforcement required. It is simply used to increase flexural strength when cracking in odd-shaped slabs needs to be controlled and where increased abrasion resistance is required for durability.

Banthia and Nandakumar (2003) have employed secondary polypropylene micro-fibres to enhance the deformation of steel fibre-reinforced concrete. More recently, Dawood and Ramli (2012) proposed the combination of steel fibres with synthetic and palm fibres as a means of reducing the corrosion problems of fibres and improving the flowing and mechanical properties of concrete. Lee et al. (2012) have shown that the blending of nylon and polypropylene fibres improves the spalling protection of FRC subjected to fire. Azhari and Banthia (2012) have blended carbon fibres and nanotubes in the development of smart stmcture materials, such as strain sensors.

Brandt et al. (1992) tested concrete slabs cast a few years ago with two kinds of concrete with basalt and limestone aggregate, with a maximum aggregate grain size of 20 mm and compressive strength approximately f2g = 25 MPa. On these slabs were cast layers of steel-fibre reinforced concrete (SFRC) after the old surfaces have been carefully cleaned and washed and their roughness has been artificially increased. The new material was... 

Considerable progress in that approach, namely in formulating rules for structural design of elements, was achieved by the work of the RILEM Technical Committee 162-TDF Test and design methods for steel fibre reinforced concrete led by L. Vandewalle (2000) and Vandewalle et al. (2003). The input from the fibres is based on the evaluation of the area under the respective portions of the load-deflection curves, related to the selected limit states. Section 10.2.4.

For example, for a high quality matrix with E = 40 GPa and = lOO.lCf and fibres made of mild steel with = 200 MPa, the critical volume fraction is equal to 0.02, assuming that the fibres are fully loaded. In ordinary steel fibre reinforced concrete elements, usually short and randomly dispersed fibres are used. However, because of the low efficiency of such fibres, even if made with high strength steel (which is the case for most present applications), in normal technical conditions the achievement of Vf is nearly impossible. If other methods of concreting are applied, like SIFCON, or when fibres with increased bond and linearized are used, then the efficiency of reinforcement is significantly improved.

The frequency of cycles has a smaller influence than the range of stress, but the fatigue strength of steel-fibre-reinforced concretes also depends upon the loading rate, which confirms the general observations made in that respect. 

S siadek (1980) performed a series of tests in which the fatigue strength of plain concrete was compared to that of steel-fibre-reinforced concrete. The fatigue strength was stabilized after for 2.10 cycles and these results may be summarized in the form of relations between fatigue strength /j and static strength...
