Quality of construction materials is important in order to ensure the design life and sustainability of roads.
Flexible pavements depend on the binder quality which is normally produced from manufactured
bitumen. Various initiatives were conducted to enhance the binding quality of bitumen. Thus, the term
modified binder is always used when additives are added to bitumen. In this innovation project, peat
particles are used as additives in bitumen thus, producing an innovative peat-modified bitumen or iPMB.
It was found that iPMB requires 5% of micro-peat particles produced by the researchers and was able
to enhance more than 50% the sustainability against permanent deformation of iPMB bituminous mix
when compared to normal 80/100 PEN bitumen. This shows that with micro-peat particles which are
produced in Malaysia was able to improve the quality of flexible road pavements constructed especially
for heavy traffic roadways.

Abstract. This study introduces the direct technique for recycling aluminum chips instead of
conventional method which will be carried out without melting phase. The hot extrusion technique is
characterized by the low number of steps and gives benefit on low energy consumption and operating
cost. It could elaborate technical process details and a systematic characterization of hot extruded
profile's properties of the recycled of AA-6061 aluminum alloy chip of different geometries and will show
the technique potential regarding yield behavior and microstructure. By following the research task, it is
reveal the performance of recycled aluminum chip on their mechanical properties and microstructure by
comparing them with the original aluminum-base composite. It is ensure to review the possibility of this
recycled aluminum chip as a secondary resources as an alternative to overcome the shortage of primary
resources in which it utilizes the metal optimally and able to lower the usage of raw metal.
