Project Description Heading link
Traditional concrete has a low ductility. In a slab such as pavement, there is a higher probability of cracking when the bottom of the slab experiences a tension load. One example where this can be seen is when vehicles drive down a roadway. The goal of this project is to increase the ductility in pavement, making it more flexible, which will allow designers to reduce the bearing capacity of the soil. In addition to this goal, the project resulted in a preferred mix design that would achieve the same or higher strength than the standard pavement mix by using a specified amount of fiber reinforcement.
Laboratory experiments were done to determine the strength and ductility of three different mixes with varying amounts of fiber in them. The test results that were gathered will show how much the concrete in pavement will flex in order to apply it on a reduced bearing capacity. The result of the experiments was a highly ductile concrete which can be determined ductile and strong enough to allow pavement to be applied with a lower bearing capacity than traditional concrete.
The research done showed that concrete that is heavily induced with fiber reinforcement would allow the concrete to flex enough to for it to be be able to apply it to an area with a reduced bearing capacity. By doing this, it will decrease the soil removal costs on roadway projects because soil that would have normally been classified as unsuitable can now be left in place.
