Development of Fatigue Models for Concrete Pavements with Rap As Coarse Aggregate
Journal Title: International Journal of Scientific Research and Management - Year 2014, Vol 2, Issue 8
Abstract
Concrete is the basic material in all construction works and coarse aggregates constitute more than 50% of the mix. But the procurement and generation of natural aggregates is getting difficult day by day because of lack of natural source and enviro nmenta l effects. In search of alternative for natural aggregates, lead to the usage of Reclaimed Asphalt Pavement aggregates, which a re produced abundantly due to replacement of Flexible Pavements with Rigid Pavements in India. This study is taken up to determin e the variation of different properties of strength and mainly durability of concrete pavements with natural aggregates and RAP aggregates. The cubes will be casted and tested for Strength and Flexural Strength is also determined by casting beams. The resu lts can be analyzed to identify the importance of RAP aggregates for its effective and efficient usage for present scenario of India. The RAP Aggregates are proc ured from NICE, Bangalore. And it is checked for the effective utilization in Concrete Pavement s. RAP aggregates are replaced with Natural Aggregates by 100%, 75%, 50% and 25% and evaluated. Also the fatigue models are developed by testing the beams under repeated loadings by considering stress ratio of 65%, 75% and 85%.
