In this research, An economical, generic, readymade stockpile cold patching mix has been proposed, which is manufactured in a batch type hot mix plant using local aggregates also this mix does not require any preparation of the pothole such as squaring and applying tack coat; the mix is simply taken out of the 50-kg bag, leveled with a rake, hit with a hand rammer by ordinary laborer (no roller), some light sand or grass/leaves is sprinkled on surface to prevent pick up by vehicle tyres, and opened to traffic right away. If there is water in the pothole, simply sweep off the extra water. The patch will outlast the adjacent road area. The mix has a storage life of at least 6 months, so it can be prepared in advance and used as needed to repair potholes as soon as they develop throughout the year. Index Terms – Pothole, Readymade Stockpile Cold Patching Mix, Hot Mix Asphalt. 1. INTRODUCTION 1.1. Background Development of potholes on Indian roads and streets is a very common phenomenon. Potholes are one of the public’s main local concerns, as they are highly visible defects. Many perceive that the quality of local roads may be deteriorating, with potholes being one of the main causes. Every year there is a public outcry and newspapers are full of pictures showing potholed road pavements. Hot mix asphalt plants are usually shut down during monsoons and no hot bituminous mix is available for filling potholes. Therefore, many potholes are either not repaired or repaired with antiquated techniques.India is said to be the fastest developing countries today only after China. Although India is doing exceptionally well in fields like education, industrialization and fashion there are still certain areas where the country is lagging behind. India's road network is gigantic and said to be only after the United States of America. But one of the striking underlying facts is the condition of the roads. India is home to several bad roads be it the metropolitans, the cities or the villages. Bad road conditions are nothing new to India and the problem is being addressed since the last 30 years. Since roads indirectly contribute to the economic growth of the country, it is extremely essential that the roads are well laid out and strong. This mix is also very handy for contractors who are responsible for maintaining national highways, state highways or rural roads during the concession or warranty or defect liability period. If there are a few potholes there is no need to arrange hot mix; take some bags of this readymade cold mix and a labourer (with a hand rammer) in a car or pickup and get the potholes repaired. It is also handy for filling test/survey pits made on the road for testing and also for filling utility cuts in city streets. 2.

Abhishek Kanoungob :The study analyzes pothole problem on the roads of Chandigarh and its causes for assessing the riding quality. 2.3 Use of Bitumen Emulsion for Flexible Road Construction (2017) - Shivani Singh Dhriyan,Yogesh Garg : In colder region it is difficult to maintain the paving temperature of hot mix. To overcome these problems and conserve the energy bitumen emulsion is considered as good option. Likewise emulsion can be used in the areas having higher rate of rainfall where the hot mix plant is closed most of the time because of rain. Emulsified bitumen can be used during rainy season and colder regions
