TENSILE PROPERTIES OF FERROCRETE OVERLAY FOR PARKING PAVEMENT

Global warming is a long-term rise in the average temperature of the Earth's climate system. Due to global temperature change its impact on Earth's climate there is extreme weather condition cause early deterioration of parking lot pavement which affects its intended design life. One of the parameters of deterioration may be in the form of uncontrolled cracking due to temperature gradient occurs in overlay slab because of temperature stresses. To overcome this type of distress in pavement there is common method of rehabilitation by providing overlay. In this Paper attempt was made to use overlay by changing material properties of concrete with reinforcing material which can reduce the early deterioration because of tensile stresses. This research investigates the use of self-compacting concrete ferrocrete overlay as effective crack arrester in overlays to increase their performance by providing additional tensile strength. This paper presents the experimental testing set up to assess and quantify the effect on self-compacting concrete ferrocrete overlay by conducting direct tension test on conventional and ferrocrete specimen. The experimental testing results show that specimen of ferrocrete overlay enhances the properties in terms of strength and ductility and this has been phenomenally observed till mode of failure. The results show that the ferrocrete specimens have higher tensile strength than conventional specimens which can be recommended to use to increase the life of parking pavement
