| Abstract | ||||
| Recycling or reusing industrial solids has become an essential global issue. The incorporation of Rockwool waste in the production of waterproofing membranes to achieve reasonable physical, mechanical, and thermal properties is investigated. The different composite mixtures of modified bitumen with polypropylene polymers and different weight ratios of rockwool waste are studied. The physicochemical and chemical tests such as softening point and penetration test for mixtures and beak load, tear strength and elongation for membranes, and water tightness are measured. The evaluation tests revealed that the best addition ratio of rockwool waste to modified bitumen that gave acceptable results is within the 68e61% of rockwool for the rock wool (RW)-B5 modified bitumen membrane sample. Also, using Rockwool waste instead of real limestone not only lowers the cost of the product but also improves its heat resistance. The thermal resistance results were enhanced by 32.15% for the RW-B5 mix compared with the reference sample (ROCK TORH). | ||||
