CAUSES OF DISINTEGRATION OF ROADS AND MAINTENANCE AND REPAIR OF ROADS

It is very important that preventive maintenance should be preferred and carried out at the first indication of such realisation, and immediately it becomes necessary as such delay will cause minor defects to develop into the major ones as a result of the traffic action or weather. Generally the failure of a road structure may be due to Inadequate drainage or poor maintenance of the drainage system. Bad design, ie insufficient thickness of construction to carry the traffic load imposed. Faulty construction of which the commonest example is inadequate compaction of the sub grade and base, poor surface maintenance and open textured road surfaces are more liable to fail than close textured surfaces. As such the source of trouble should always be determined before making repairs. Surface repairs on a defective base or sub grade is a waste hence the condition of the road base should always be investigated. Undue strengthening of the week spots may create difference in traffic wear and impact which cause additional damage to the adjoining surface areas. Every effort must be made to reduce interference with traffic with good organization of repair work where warning signs and barriers should be carefully sited. As for the special repairs are concerned there should be an appropriate maintenance record of the inventory control of the Re - metalling, so that essential provision should practicable in routine duty of the schedule for premixing. Every department of the road construction is responsible to prepare the inventory control of the roads and it's  record related to the such duty, so that the operation of the special repairs should be carried out in routine for the procedure laid down under the properly designed methods of the surface dressing and it may be useful for much heavier traffic and increases the life of the road considerably:-- Er Fateh chand Guleria, Director RTI welfare Association registered number HPCD, 3552 , Bilaspur Himachal pradesh phone number 9459334377
