摘要：	The rapid growth in road construction brought about considerable expansion of road infrastructure, which subsequently fell into disrepair through lack of maintenance. The damage is often so severe that ordinary maintenance will no longer suffice and if roads are to be fully restored, rehabilitation or even reconstruction work is necessary, at a life cycle cost three to seven times higher than that of preventive maintenance strategies. Rigid pavements have a relatively long service life if these are properly designed, constructed and maintained. Rigid pavements can serve up to its design service life and even beyond if timely repairs are undertaken. All types of pavements deteriorate with time. Rate of deterioration is comparatively much slower than flexible pavements. Pavement Maintenance is more than just a collective set of specific pavement maintenance techniques. It is a way of thinking and the guiding force behind an agency's financial planning and proper asset management. Pavement management must be tailored to each road agency's system needs to cater to the need of various pavement distresses in the most cost effective manner. This involves using a variety of treatments and pavement repairs to extend the pavement life. The most of the Pavement Designs involve two or more performance periods. A pavement is constructed at an initial serviceability level, and is rehabilitated to an acceptable level at some point of time during its design life. This process of rehabilitation may be repeated several times depending on the condition of the existing pavement deteriorating from time to time A Maintenance Management System (MMS) is a technique or operational methodology for managing or directing and controlling the judicious use of maintenance resources. Effective MMS is doing the correct thing at the correct time and in the correct place. For modern Rural Roads, Roads & Highways, to be operated efficiently and effectively for the benefit of all users, it is required to meet customer's defined requirements. Road drainage performance plays a vital role in ensuring the pavement performance. Road Management System needs to be established on a computer system platform on client server model at the headquarters of Ministry of Road Transport & Highways (MORTH). Softwares for GIS, HDM, Image Processing Software, Terrain Modeling, Software and AutoCAD may be required for the proposed planning model. A resourceful consortium of Consultants having expertise in all these areas could be required to develop the system on a turnkey basis and hand it over to the client, after customizing and operationalizing it.
