The study aims to investigate using rock asphalt from the city of Hit—Hit rock asphalt—in the fine aggregate of asphalt mixtures. Hit rock asphalt was ground, passed through sieve 2.36 mm and retained on sieve 0.3 mm resulting in a "fine rock asphalt”, F-RA. 10%. 20% and 30% of F-RA by aggregate weight was used as the fine aggregate in asphalt materials. Permanent deformation of F-RA-modified asphalt mixtures was investigated and cracking of these asphalts was also measured using indirect tensile strength of the mixtures. Moisture damage of the F-RA-modified asphalts was also investigated. The results showed that F-RA has a potential role in improving the resistance of asphalt mixtures against rutting, and, there was also an improvement in the resistance against cracking and moisture. In summary, it can be recommended that The optimal percentages of F-RA in the fine aggregate was 20%. |
