INTRODUCTION
This paper is a proposal on the utilization of waste materials such as in pavements and roads. A
huge quantity of industrial products and non-renewable materials such as lime, cement, bitumen,

and aggregates are consumed during the maintenance and construction of pavements and roads.
As the volume of waste materials and by-products produced in the society and the disposal cost
continue to increase due to development activities, urbanization, and population growth, there
are increased incentives and pressure to recycle and recover these materials for the use in
secondary application such as pavement and road construction (Nouali, et al., 2019). The high
cost of materials, depleting of construction resources, environmental deterioration, and wastage
of materials have promoted the use of waste materials in construction.
PROBLEM STATEMENT
Civilization caused by urbanization and population growth have resulted in massive production
of waste products that are non-ecofriendly, hazardous, and some of which are non-biodegradable
have resulted in environmental pollution and waste disposal crisis. These waste materials include
plastic wastes, rubber wastes, PET bottles, and plastic carry bags which are generally found in
every waste disposal site (Ashok & Sopan, 2019). This article proposes the possibilities of
using waste materials in the construction and maintenance of roads and pavements to replace the
traditional materials that have proved to be costly and depleting.
RESEARCH QUESTIONS
The following are some of the formulated research questions that would be effective for this
research proposal:
 Which are some of the waste materials that can be used in road and pavement
construction?
 What are the physical properties of plastic waste or PET that make them effective
construction materials?
 What is the procedure of using waste materials in construction?
 What are the stability and strength characteristics of waste construction materials?
