PATCH-FILL Automated Pothole Repair Machine 

Yet another, one of its kind machine in the world, Patch-Fill is ultra compact, powerful and largely automated Pothole repair machine to fill the potholes on any pavement in fast, standard and durable manner. Designed by CSIR-Central Road Research Institute (CSIR-CRRI), these machines are ideal for working in remote and congested places like city streets and hilly terrains where working with big truck mounted imported machines is difficult, costly and blocks traffic for a long time. Through technology licensed to Petrochem Specialities for production of these machines, CSIR-CRRI has chosen a dependable partner to cater and take care of Pothole problems on roads belonging to PWDs, Municipal corporations, NH, NHAI and Expressways. Since this machine is 100% made in India with fully indigenous technology from premier road research institute in India, it is a way forward to "Atmanirbhar Bharat" and "Make In India" initiative of the Government of India and a major foot forwards towards making Indian roads safe and keep well the good riding quality. This machine consumes very less fuel and provide on-site mixing of ingredient for better compatibility and super fast working with unmatched quality control.  

Patch-Fill mobile automated machine has been designed, keeping in mind for various challenges faced by the road engineers and contractors in keeping the roads Pothole free to ensure safety of travellers and reduce fuel consumption / maintenance in vehicles due to smooth ride. This machine is specially built to work on roads in areas having width limitations, small city streets, hilly roads etc, however due to its compactness it can be efficiently used on major roads and expressways to tackle the Pothole problem at its start and to prevent it from progressing to bigger potholes like pavement distress and base failure.  Even though it has smaller capacity, this machine is infused with lot of power in terms of operation and are built to handle tough challenges even in difficult terrains. With choice of very compact chassis for better maneuverability, this machine has exceptional work quality with a variety of materials and climatic work conditions. With maximum Indian components, this machine is built tough with easy to control instrumentation to ensure operator friendly work environment.


With simple electronic process control based on PLC, the operation of this machine is simple through Touch Screen HMI. First in its class, the electronic calibration console is integrated with the operation program for easy and accurate estimation of each individual component output. Powerful hydraulic motor from among world's best companies drive the mixing operation. Pneumatic synchronization of dosing operation ensure best operator compliance. The high efficiency single shaft multi paddle pug mill ensure best mixing of components before their discharge into the pothole.

Apart from PLC based automated sequencing, special provisions have been done for electronic over-ride and control of dosing of twin components to ensure real time control of mix consistency. This machine is built strong with simple yet powerful mixer, chemical resistant paint coated pipelines, stainless steel tanks, antistrip anti-scratch coating on aggregate bin etc., apart from pneumatically operated valves and system integration.
