Laboratory Evaluation and Field Observation of Cold Patch Repair Mix Prepared with Coal Mix Waste Aggregate and New Binder Formulation (Bond-1, 2)

The deteriorating highway culvert infrastructure has become a major challenge for the 21st century. While more significance normally is given to highway embankments, pavements and bridge, the support of courses has ordinarily been disregarded. Cracks, Potholes, and patches are some types of road surface distresses whose assessment is essential in India. Normal and new approaches which target the medium- or long-term repair of potholes have been studied. In a catalogue of tests, evaluation methods and experiences according to existing Standards have been compiled to give road agencies an overview of the possibilities for the repair of potholes. Furthermore, the testing of techniques and the use of material types from already existing trial sites have been used to determine properties of materials and their related laboratory tests which can, or should, be used to select the correct testing of materials for this purpose. Potholes, cracks and patches are some types of road surface distresses whose assessment is essential in India (MORTH, 2004). To the motoring public, potholes are one of the most visible and annoying forms of pavement distress. Waste aggregates, which is present in coal mines. These waste aggregates can be of great use in coming future. So, our main aim is to utilize this waste into something productive and for this purpose, various tests have been carried out on Coal mixed waste aggregates, which have been taken from NTPC Thermal Power Plant.
