PHYSICAL CHARACTERIZATION OF POLYURETHANECLAY COMPOSITE DOPED WITH TREATED AND UNTREATED PU WASTE AS FILLER FOR SUBGRADE LAYER APPLICATIONS

One of the most efficient ways to enhance the geotechnical characteristics of soils is to use polyurethane waste as a filler. In this study, the PU waste was soaked in a 0.05 M sodium hydroxide (NaOH) solution as an alkaline cleaner before being sieved to a size of 300 m. Then, the PU waste as fill...

In this study, the PU waste was soaked in a 0.05 M sodium hydroxide (NaOH) solution as an alkaline cleaner before being sieved to a size of 300 m. Then, the PU waste as filler was dried in microwaves and a drying oven.
