Chennai City

           Chennai City is the biggest and important urban agglomeration in TamilNadu.  This City portrays both historical and modern contemporary Indian culture.
           It stretches nearly 43 kms along the coast of Bay of Bengal from Uthandi  the erstwhile village panchayat in  the south, to Kathivakkam the erstwhile municipality in the north. It has Bay of Bengal as eastern boundary and remaining three sides are surrounded by Kancheepuram and Thiruvallur Districts.
           Chennaipattinam, a tiny village on the east coast of India, has transformed into a magnificent city, which is now the fourth largest metropolis in the country. It can be best described as a city with a unique and harmonious blend of tradition and modernity. The city was established in the 17th century by the British, who developed it into a major urban agglomeration.
           By the 20th century, it had become an important administrative centre, as the capital of the Madras Presidency. The East India Company issued a charter constituting the “Town of Fort St.George” and all the territories there unto belonging, not exceeding the distance of ten miles from the Fort, into a Greater Chennai Corporation on 30th December 1607.  
           The Corporation of Chennai was established on the 29th September 1688. The Parliamentary Act of 1792 gave the Corporation, the powers to levy municipal taxes in the city. The Chennai City Municipal Corporation, Act, 1919 provides the basic statutory authority for the administration of the City.

Expansion of the limits of the Corporation

          The city has been growing both in size and population. The number of territorial Divisions have grown from 30 with 68 Sq.km in 1901 to 200 divisions with 426 Sq.Km in 2011.The population of the city has gone up from 5.40 lakhs in 1901 to approximately 65 lakhs in 2011. The boundaries of Chennai city with an extent of 174 sq.km. were fixed in 1978.  The Chennai Metropolitan Area (CMA) has experienced rapid growth in the past years and the Corporation encounters multidimensional challenges. It is therefore imperative on the part of the local bodies to provide suitable infrastructure to keep pace with the growing demand. The level of services provided by the local bodies in the CMA varies to a large extent. The capacity to  effectively deliver these services can be catered better only by an organized urban local body like a Municipal Corporation, instead of  a cluster of Municipalities, Town Panchayats and Village Panchayats. 
          Therefore, the Government decided to expand the boundaries of the Corporation from 174sq.km to an extent of 426 sq.km by amalgamating 9 Municipalities, 8 Town Panchayats and 25 Village Panchayats adjacent to the Chennai and issued orders in G.O. (MS) No.256, MA & WS (Election2) Department dated 26.12.2009 and G.O. (MS) No.280, MA & WS (Election) Department dated 09.11.2010.

In Chennai City  after expansion  Roads to a length of 387.35 Kms are Bus Route Roads. Bus Route Roads Department of the Greater Chennai Corporation maintains and improves all the Bus Route Roads periodically. The Bus Route Roads are being re-laid once in 3 years using paver finishers. The relaying of Bus Route Roads consists of laying Compacted Bituminous Concrete(CBC) 40mm thick wherever the existing base is badly damaged the road is strengthened by laying base course with DENSE Bituminous Macadam ( DBM ) 50mm thick. The unit cost of laying the Bus Route Roads as mentioned above is Rs. ------/- per Sqm as per current schedule of rates. (2012-2013 )The hot mix required for the relaying work are prepared by the contractors in their centralized Asphalt plant located in the outskirts of the City and brought to the site by tipper lorries, and laid at the site using mechanical paver finisher and rolled with vibrator rollers and static rollers.    From the year 2011 – 12 all the   bituminous roads are being relaid by adding waste plastic in the aggregates(only in wearing course) temperature of the mix at all stages are strictly adhered as per the MORTH Specifications This makes it possible to achieve uniform and smooth riding surface. The process of laying roads in this manner is also very fast and causes less hindrance to traffic. In order to avoid traffic disturbances, Bus Route Roads are normally laid during the night  hours and is opened to traffic in the next morning. The entire process of relaying Bus Route Roads is being carried out in accordance with the specifications of Ministry Of Road Transport and Highways ( MORTH ).

Mastic Asphalt

Mastic Asphalt Concrete is being laid as a wearing course for a thickness of 25mm at all important junctions and signal points of the Bus Route Roads. Mastic Asphalt concrete is capable of withstanding the force generated when brakes are applied by heavy vehicles and the force generated due to initial wheel momentum. In order to avoid damages to the road surface due to the application of brakes, this special technique is being used.

Patches And Potholes

Apart from periodical relaying of City Roads, the patches and potholes arising out of the road cuts made by the Service Departments and due to inundation of rain water during rainy season are being attended immediately by using bituminous  Hot Mix  being prepared Departmentally in corporation owned Central Asphalt Plant located at Chetpet.
