Study and Analysis of Highway Failure and Their Maintenance

Abstract

Maintaining highways is crucial to ensure road surfaces are safe and smooth for drivers, ultimately loading to efficient and cost-effective transportation. Regular maintenance helps prevent accidents and reduces the overall cost of road repairs in the long run. The investigation found that the authority of RCC performs their maintenance work in one year when allocated funds are available. Many types of road failures oc, such as cracks, pot-holes, ravelling, water bleeding, corrugation and showing, depression, and rutting. The possible causes of flexible pavement failures are improper bituminous mixes with poor quality materials, heavy traffic loads,heavy rainfall, and bad drainage on pavement. The failures are gradually raised due to a lack of proper planning, inspection, and treatment. These failures create different types of disadvantages like traffic jams, discomfort to the passengers as well as drivers, increasing vehicle operating, maintenance costs, etc

Introduction

I. INTRODUCTION

The development of a country depends upon a transportation system and the transportation system should be well-developed in roads, railways, waterways, and airways. A well- developed transportation system, encompassing roads, railways, waterways, and airways, plays a crucial role in the development of a country. It facilitates the efficient movement of goods and people, reduces communication costs, and ensures the timely arrival of essential commodities. This infrastructure is a cornerstone of economic and social progress. Indeed, road transportation plays a crucial role in connecting people and communities, providing access to goods and services, and facilitating various aspects of daily life in a complex society. It's often the most accessible and versatile mode of transportation, especially in remote areas. That's correct, roads can still experience failures despite careful construction.

Factors like weather, heavy traffic, and maintenance play a role in road durability. Maintenance is crucial to extend the road's lifespan, reduce vehicle operating costs, and ensure it remains in a serviceablecondition. Road pavements are generally divided intotwo main types based on their structural and design purpose: flexible pavement and rigid pavement. Flexible Pavement: This type of pavement is constructed using multiple layers of materials, with the top layer being asphalt concrete. Flexible pavements are designed to distribute the load from traffic over a broader area, allowing for some flexibility and deformation. This makes them well- suited for roads that experience heavytraffic and need to withstand varying weather conditions. Rigid Pavement: Rigid pavements are typically made of concrete and are designed to be stiff and unyielding. They distribute the load more effectively than flexible pavements, making them suitable for areas with heavy traffic loads, such as highways and airports. Rigid pavements tend to be more durable but are less forgiving when it comes to temperature- related expansion and contraction. The choice between flexible and rigid pavement depends on various factors, including traffic volume, environmental conditions, and budget constraints. Each type has its advantages and disadvantages, and engineers select the appropriate pavement design based on the specific requirements of the road or highway project..

II.  LITERATURE

The term pavement ordinarily means the surfacing layer only. But in highway design, it means the total thickness of pavement that includes surface, base, and sub-base What you're describing sounds like a road or pavement. Roads are constructed with material layers to provide a stable and even surface for vehicles while distributing the load to the natural soil subgrade. Flexible pavements, such as asphalt roads, are more prone to various types of failures like cracking, rutting, and potholes due to changing weather conditions and heavy traffic loads. Regular maintenance is essential to extend their lifespan and ensure safe and smooth travel. may include patching, resurfacing, and seal coating, depending on the specific issues that arise. The flexible pavement layers reflect the deformation of the lower layers on the surface of the layer.

Development typically goes Highway through several stages, from planning and design to construction and maintenance. These stages may vary in detail and order depending on the specific project and location, but here is a general overview of the stages involved in highway development:

A. Planning and Feasibility Study

Highway development is a complex and lengthy process that involves collaboration among various stakeholders, including government agencies, engineers, environmental experts, and construction companies. It's important to note that each project may have unique requirements and considerations, and local regulations and practices can vary significantly.

III. HIGHWAY MAINTENANCE

Highway (road) maintenance is defined as preserving and keeping the serviceable conditions highway as normal as possible and practicable. The main objectives of road maintenance men are the allocation of available maintenance resources according to actual needs and priorities.

A. Surface Maintenance

1. Preventive Maintenance: Preventive maintenance involves proactive measures to address minor issues before they escalate into major problems. This may include sealing cracks, applying surface treatments, and patching small potholes.
2. Repairs: When road surfaces develop significant damage, repairs are necessary. This can involve patching or resurfacing sections of the road to restore its integrity and smoothness.

B. Traffic Service

1. Traffic Management: This involves monitoring and controlling traffic flow through various means, including traffic signals, signs, and variable message signs (VMS). Traffic management aims to reduce congestion, prevent accidents, and improve overall road safety and efficiency.
2. Traffic Signals: Traffic signal systems are used to control the right-of-way at intersections and along roadways. They help regulate traffic flow, reduce conflicts, and improve safety.
3. Traffic Enforcement: Law enforcement agencies play a critical role in enforcing traffic laws and regulations. This includes issuing citations for speeding, reckless driving, and other violations to promote safe driving behavior.

C. Roadside and Drainage

1. Ditch Maintenance Cleaning and reshaping roadside ditches to allow for proper drainage of rainwater and prevent flooding.
2. Shoulder Maintenance: Roadside shoulders provide a buffer zone between the road and adjacent areas. Regular maintenance of shoulders involves clearing debris, controlling vegetation, and ensuring proper grading to prevent erosion and provide a safe area for drivers to pull over in emergencies
3. Wildlife Management: In some areas, wildlife can pose a hazard to drivers. Implementing measures like wildlife fences and warningsigns can help mitigate these risks.

D. Shoulder & Approach

1. Emergency Stopping: One of the primary functions of the road shoulder is to provide a safe area for drivers to pull over in case of emergencies, such as
2. Pedestrian and Cyclist Use: In some areas, road shoulders may be designated for use by pedestrians and cyclists, providing a separated space for nonmotorized transportation.
3. Parking and Overtaking: In some cases, road shoulders may be used for temporary parking, overtaking slower vehicles, or as a transition area for vehicles entering or exiting the road.

E. Bridge

1. Bridges require regular inspection and maintenance toensure their safety and functionality
2. Maintenance activities may include painting, deck resurfacing, structural repairs, and corrosion prevention.

Environmental Considerations: The construction and maintenance of bridges can have environmental impacts, such as altering water flow patterns or affecting wildlife habitats. These factors are considered in the planning and design stages.
