INTRODUCTIONWASTE ARISING AND MANAGEMENT OF SOLID WASTE
• With the rapid economic growth and urbanization take place
currently, Malaysia is facing an increase of the generation of
solid wastes accompanying with the disposal of wastes.
• More production equals more waste, more waste creates
environmental concerns of toxic threat.
• Need to allocate more landfills and spend a lot of money on
transport, labour and maintenance purposes.
STATISTIC FINDINGS REGARDING WASTE
MATERIALS
56%
2%
42%
Percentage of Waste Materials
Landfills
Recycled
Incinerated/Chemical
Data acquired from DOE of Malaysia
• In Malaysia, only 2% of municipal wastes is recycled.
• Only about 42% is incinerated or chemically treated.
• The rest 56% is dumped into landfills to decompose or not to decompose
Here are some important statistics :
• increase amount of disposal waste -> Lead to illegal dump
-> causes pollution
DEMAND IN INNOVATION OF ROAD CONSTRUCTION
• Through research and statistics of increased in traffic
volumes, tyres pressure, heavy axle loadings, speed of
traffic and environmental concerns, the innovation for
road construction are very demanding.
CONTINUOUS REDUCTION OF NATURAL RESOURCES
• Reduce the productivity of natural resources as well as
reduce the energy consumption of materials production
and all its associated pollution
According to the review of related literature,
Several number of studies suggested that the utilization of recycled and waste materials as substitute in asphalt mixture materials would be the one of the solutions.
PROBLEM STATEMENTConcerns mainly on the feasibility of utilizing recycled and waste
materials in Malaysian pavement construction.
Main problem : to investigate whether the applications of R&W
materials in Malaysian pavement construction are SIGNIFICANT
in actual construction and past/current research.
Investigate the experts’ perceptions and acceptance towards
utilization of R&W materials as substitutes in asphalt mixture
materials.
The research is based on two methods:
• Comprehensive review of available literature regarding
the utilization of recycled and waste materials in pavement
construction
• Conduct survey and interview to obtain experts
perceptions and acceptance regarding the utilization of
recycled and waste materials in Malaysian pavement
construction
OBJECTIVES
To determine the extent of the utilization of recycled and
waste materials in Malaysian pavement construction and
also to identify the characteristics and possible uses of
various recycled and waste materials as substitutes for
conventional asphalt mixture materials.
SPECIFIC OBJECTIVES
1. To identify the potential recycled and waste materials that
could be utilized as substitutes for conventional asphalt
mixture materials and its characteristics, based on the past
and current research and implementation.
2. To assess the economical and engineering implications with
the utilization of recycled and waste materials in asphalt
mixtures as compared to the conventional asphalt mixture
materials.
3. To identify the suitability, advantages and limitation of
recycled and waste materials to be utilized as asphalt
mixture materials and thus to provide solution if possible.
4. To evaluate perception and acceptance of recycled and
waste materials as substitutes for asphalt mixture
materials from respective parties involved with the
Malaysian pavement construction.

1. Awareness on Recycled and Waste Materials Utilized in Pavement Construction Applications
2. Knowledge and Awareness on Recycled and Waste Materials Utilized in Pavement Construction throughout the World
3. Knowledge on Practical Use of Recycled and Waste Materials in Malaysian Pavement Construction
4. Response on Limitations of Utilizing Recycled and Waste Materials in Malaysian Pavement Construction
5. Response on Benefits of Utilizing Recycled and Waste Materials in Malaysian Pavement Construction
6. Specific Standard on Utilization of Recycled and Waste Materials In Malaysian Pavement Construction
7. Recommendations towards Development of Utilizing Recycled and Waste Materials in Malaysian
Pavement Construction
1. revise the current standard, specifications and regulations regarding the utilization of recycled and waste materials in pavement construction.
2. encourage the existing pavement construction industry to implement this green technology
3. more conference and seminar should be held to introduce the availability and applicability of utilizing recycled and waste materials in pavement construction industry as well as enhancing awareness and knowledge regarding the utilization of recycled and waste materials
DISCUSSIONS
• many positive impacts through different aspects which
includes the benefits in enhancing the sustainability of
pavement construction industry, reducing cost of pavement
construction, providing solutions to environmental pollution
and reduce the needs of using virgin materials (i.e natural
aggregates, sand and etc).
• in Malaysia, the use of reclaimed asphalt pavement, crumb
rubber and recycled concrete are still limited for road
rehabilitation only, and not yet to be widely develop in the
actual pavement construction.
CONCLUSIONS
From the review of literature and analysis of data from interview and questionnaire,
• Results indicated that some respondents were not aware of the availability, quality of the materials’ performance, cost savings, or any other benefits including environmental benefits of utilizing recycled and waste materials
• The barrier of not utilizing recycled and waste materials were revealed.
• the utilization of R&W materials should be scrutinized by related government agencies and road authorities to give new dimension on the existing technology in pavement construction
RECOMMENDATIONS
Enhance awareness among players in pavement construction
• Organize seminar and conference to promote and introduce this new technology extensively to the players in pavement construction industry.
• Waste and recycling management plans should be developed for any construction project in order to sustain environmental, economic, and social development principles.
• Government should encourages recycling by legislation, purchasing power and grants that are offered to companies to help initiate recycling locally
Extensive Research on the Potential Recycled and Waste Materials
• Further investigation on the effects of different recycled and waste materials on its durability performance as substitute in asphalt mixture materials
• Establishment of environmental benefits and life cycle assessment of recycled and waste materials and their applications in construction industry especially in pavement construction.
• Create better documentation
Applications in the pavement construction
• Further development on recycling facilities and equipment , develop potential recycled and waste materials and method of construction for recycled and waste materials.
• Establish the legislation, regulation, guidelines and specification in regard of utilization of recycled and waste materials in Malaysian pavement construction.
• Commercialize the utilization of different recycled and waste materials in the production of asphalt mix materials with collaboration with the industries
