What is it about?
Optimizing the post-disaster recycled pavement material utilization into new pavements needs to be done to reduce the use of new materials. However, it is necessary to consider the utilization of post-disaster road pavement materials, due to the properties of these materials having changed. Therefore, this research aims to determine the basic properties of recycled pavement materials after the disaster in Palu City.

Why is it important?
The results showed that the basic properties of recycled aggregates still met the specifications in general, except for aggregate gradation. Meanwhile, the recycled bitumen did not meet the 60/70 penetration bitumen specifications. So, using recycled material in a new pavement mixture requires some adjustments, such as limiting the percentage in the new pavement or using additives/rejuvenators to restore the viscoelastic properties of recycled bitumen.
Perspectives
I hope that the results obtained through this article can be one of the references for using recycled road pavement materials after the disaster.
