3. ABSTRACT
There are various factors which cause deterioration of roads. The objective of our
paper is to study the effects of rain during monsoon season in India. In India,
there is a big problem of destruction of roads during monsoon season due to
heavy raining. The roads investigated experienced severe failure like cracking,
potholes, etc. there are impacts also on road transport system, accident is the
major problem due to wet surface and widening of potholes. Here, objective of
this paper is to study how the roads can be prevented from destruction and road
users from accident due to raining. The study involved different reasons having
impact on road transport and their mitigation measures during raining mainly in
North West monsoon season in India. Rain causes significant drops in traffic
speed and volume. Heavy rain can induce road waterlogging especially in the
developing countries due to their poor drainage systems, which will exacerbate its
effect on transportation systems. Various factors including expansive subgrade
soil and use of inferior material are common causes of destruction and wet roads,
widened cracks and potholes etc. Hence, rains lead to delays on high extent and
impacting transport by road. Accidents due to rain, fog, sleet, wet pavement etc.
come under the category of weather related accidents. Essential objective is to
reduce the accidents caused due to rain. Broadly, the study includes identification
of impacts caused by rain to transport system and their remedies.

4. AIM & OBJECTIVES
 AIM
To study the effects of rains on roads (both Cement
Concrete & Bitumen) thus to the transport system and
to provide best possible solutions to reduce such
effects and thereby accidents on roads saving lives of
the people.
 OBJECTIVES
1. To study the effects of rains on the Cement
concrete and Bitumen roads.
2. To study the impact of such effects on the
transport system.
3. To study the impact of those effects on the lives &
Livelihood of the people.
4. To provide best possible solution to reduce such
effects for providing effective transport systems.

5. INTRODUCTION
 Road transport plays a significant role in the progress of social and
economic development of country because 90 percent of Indian passengers
travel by road and 65 percent of goods also transported by using road
transportation.
 Now a days we are using roads for transportation as well as for
communication.
 But these are effecting the roads and damaging them leading to traffic and
road accidents etc.
 The damage of roads is also due to continuous rain fall and change in
climatic conditions as well as leaking of chemicals on roads.
 Due Poor roads it is difficult to transport from one place to another place
which leads to loss of time.
 Poorly maintained roadways cause accidents in a variety of ways, mostly
due to the fact that they create an enormous hazard to drivers. In many
instances, a driver may attempt to avoid a certain situation, like a pothole or
pooling water which could cause a serious accident.

6.  The ministry of road transport and highways disclosed that as many as
4,775 accidents occurred in 2019 due to potholes and 3,564 such accidents
were reported in 2020.

Studied effects of monsoon season or rainy season, the road
pavement deteriorates due to various factors like poor
drainage, low quality of pavement materialslet the rain
water to penetrate through the pavement due to which
various distresses like cracks, potholes, depressions, rutting,
ravelling etc.

Studied effect of poor drainage condition on road is very
adverse. It causes the failure of road in different ways.
Proper drainage system provided to the road increases the
life of roads. But the improper drainage system causes the
failure of the road at its early edge. Therefore effective road
drainage should be taking into consideration during
construction of roads.

Studied effects of Poor drainage conditions on road
pavement are of adverse effects and causes failures in
different ways. Proper and well maintained drainage
systems provided to road pavements will increase their life
span but improper and not well maintained drainage
systems causes’ failure of road pavements at its early age
thereby drastically reducing their service lifespan.

Studied effects of The loss of bitumen-aggregate bonding
strength due to moisture damage in asphalt mixtures is
investigated. General description of the theories and
mechanisms related to moisture damage are discussed.
Contributing factors to moisture damage and methods to
improve the bond between bitumen and aggregates are
presented.

Studied effects of Moisture damage in an asphalt mixture
can be defined as the loss of strength, stiffness and durability
due to the presence of moisture leading to adhesive failure at
the binder–aggregate interface and/or cohesive failure within
the binder or binder–filler mastic.

Studied effects of water damage test procedures on
compacted mixtures measure the loss of strength and
stiffness, both cohesive and adhesive, of an asphalt mixture
due to moisture.

9. SUMMARY OF LITERATURE SURVEY
 The study shows that there is impact of rainfall on subgrade strength of
road, pavement, shoulders, drainage etc. which causes failure of road and
road transport also influenced.
 The improper drainage system causes the failure of the road at its early
edge. Therefore effective road drainage should be taking into consideration
during construction of roads.
 The loss of bitumen-aggregate bonding strength due to moisture damage in
asphalt mixtures is investigated. General description of the theories and
mechanisms related to moisture damage are discussed.
 As water penetrates the asphalt, water enters the base material under the
asphalt. This weakens the asphalt and reduce the load capacity of the
underlayer.
 As traffic drives over the weakened area, the asphalt begins to crack and a
potholes is formed.
 Asphalt is much more malleable than concrete, which gives it many
advantages but makes it more susceptible to damage under extreme heat.
Excessive heat can cause softening, sloughing, pitting, and might deform
your asphalt under heavy loads.
