Abstract:- India is one of the fastest developing country in the world and India has 2nd largest road network in the world. Road network plays important role in transportation sector. This large network is deteriorating fast and needs to be maintained. This needs maintenance management system. For the preparation of Road maintenance management system distress analysis and condition assessment is required.
This study deals with the measurement of distress quantity and distress severity to define the condition of road network in sangli district as a study area. By analyzing this distress data the priorities for the maintenance work for selected road network is defined and is developed maintenance system.
Keywords: Distress analysis, Deterioration, Assessment

INTRODUCTION:
Road network play important role in the transportation sector. India has the 2nd largest road network in world in which the part of rural road network is large. Population growth rate of country is high so the percentage of road users increases. So for the safe travelling there is need of well-maintained road network. So in preparation of road maintenance management system distress analysis and condition assessment plays an important role.
Distress type, distress severity and condition of road recommends maintenance and repair plan according to type and age of road section. This paper aim to detection of the distress, calculation of distress quantity, measurement of its severity and define the condition of the road network of sangli district

Methodology:
The work undertaken for the study includes detection of distresses in asphalt pavement by physical inspection. The condition analysis of pavement is done by finding pavement condition index for the particular section of pavement. Overall condition assessment is done and rating is give to the pavement. Distress analysis and severity of the distress is measure according to American society of testing material (ASTM D 6433-07).[10]
-
Pavement distress:
Any indication of poor or unfavourable pavement performance or signs of impending failure; any unsatisfactory performance of a pavement short of failure .There are nineteen pavement distress obtained in pavement these are following 1) Alligator cracking 2) Bleeding 3) Block cracking 4) Bumps and sag 5) Corrugation 6)
Depression 7) Edge cracking 8) Joint reflection crack 9) Lane/shoulder drop off 10) Long. And trans. Crack 11) Patching
and utility cut 12) polished aggregate 13) Potholes 14) Railroad crossing 15) Rutting 16) Shoving 17) Swell 18) Slippage cracking
19) Revelling /Weathering

Distress analysis:
Distress analysis includes detection of distress in pavement and its measurement. Distress is detected by physical inspection method and the measurement of distress is done according to manual of American Society of Testing Material manual (ASTM).[10] Calculation of distress quantity and its severity is also part of distress analysis
-
Condition assessment:
Pavement condition assessment is done by calculating pavement condition index and rating will be give according to pavement condition index rating scale.
Pavement condition index is calculated according to the (ASTM D 6433-07) [10] manual and pavement condition rating scale is numerically divided in between 0-100. By using this scale the condition of road network is calculated

From above research work following points are concluded:
Raveling or weathering is more severe problem in pavement as compared to other distress.
Out of 6 state highways 5 state highways are above satisfactory condition and out of 20 MDR 6 roads are above satisfaction condition and remaining 14 roads are in poor condition. About 60% of roads are in poor condition so they are not fulfilling the safe driving condition.
