2. INTRODUCTION
• Urban roads which are located within the boundaries of a particular area
are known as urban roads To much the global demand of roadway
connectivity need of urban road construction ,maintenance and
management has turned into a major research area over the years With the
growth in global population and infrastructure, requirement of proper mode
of transportation has become an integral part of urban roads.
• On an average the countries all over the world spend around only 20–50
percent of what they should be spending on maintenance of their road
network.
• This shows a lack of interest and improper management system for road
maintenance which need to be upgraded in order to achieve a better
transportation system.
• Causes severe failure like cracking, bleeding or flushing, potholes etc.
• Which impacts the road transport system and increase the chances of
accidents.
4. WINTER ROAD AND MANAGEMENT
• Winter weather has a significant impact on
road safety. Reduced friction levels, ice
formationon the road and poor visibility due to
blowing snow contributes to increased
collision risk.
• The commonly used methods are salting,
sanding, direct liquid application, and plowing
8. CONCRETE PANELS AND CONCRETE OVERLAY
• Ultra-high-performance fiber-reinforced concrete add to the
strength of concrete buildups because of its high density
microstructure and damage-negotiating features.
• Conventional concrete has better workability and easily
procurable. Compared with other concretes, it is cost
effective and a longer life span.
• Pavement Repair Using Rapid Setting Concrete This type of
mixture is personalized for obtaining high strength in the
early stages. Within a few hours, the desired strength is
obtained.
• Problems like air voids, less consistent mixture, alkaline
silica reactions and increased micro cracking. The problem
of scaling is a major one.
11. ASPHALT OVERLAY
• Asphalt pellets is highly energy-efficient and could reduce
traffic disruption and improve health and safety conditions
for operators.
• The use of asphalt pellets is to repair potholes by using
induction energy.
• This technology ensures less power consumption as it is
only heated once before filling the holes. Rehabilitation and
distressed bituminous and concrete pavements are done
with Asphalt concrete overlay.
• There are five pre-overlay repairing methods which are
generally applied.
• These are milling, mill and relay, cold in place recycling,
patching of surface and no treatment.
13. GROUTING
• Grout is a dense fluid majorly comprising of cement
paste and cement mortar which is used to fill cracks or
gaps.
• The process of applying this mixture with application
of pressure is known as grouting.
• The same concept can also be used to replace the
cement mortar with different chemical substituents,
which can be applied on flexible pavements to repair
the cracks.
• The semi-flexible urban pavement grouting materials,
mainly consisted of cement, coal ash, mineral powder,
and water along with cement paste and cement mortar.
14. SHINGLING
• Shingles are a covering consisting of individual
overlapping elements These elements are typically flat,
rectangular shapes and laid in courses from one end of
the pavement to the other end of it, with each successive
course overlapping the previous one at joints.
• This type of repairing technique is preferred in the
locations where the pavement is very sensitive to
temperature and need to be protected from the high
variation in temperature or extreme weather conditions.
15. GRADING
• Grading is a very basic process of constructing any new road,
where the landscape construction has to ensure a level base, or
has a specified slope for a construction work such as a
foundation, the base course for a road or a railway, where
surface drainage designs are to be taken into account to provide
a specified slope.
• While upgrading the earthen roads into an urban road, grading
is the only preferred option available out there.
16. LITERATURE REVIEW
• Debarshi Sahoo,(2020), Urban Road Maintenance
Management & Repairing Techniques
• To match the global demand of roadway connectivity need of
urban road construction, maintenance and management has
turned into a major research area over the years.

High Resolution Satellite Images by Machine Learning

17. SUMMARY
• Different types of urban road maintenance management system and
repair techniques has been compared and studied.
• It was found that the maintenance management systems are
developed based on a number of case studies, but can also be
implemented in similar type of environment.
• The different available repair techniques like overlay, patching,
bridging, grading, piping etc. also covers a wide range of problems
and can be implemented directly after investing the proper cause of
the damage.
• i . GIS-based road maintenance management tools can assist in
decision making regarding maintenance prioritization of urban
roads.
• ii. UHP-FRC can impart high yield strength & longer life span of
pavements which can be used for immediate road maintenance.
