| Atterberg Limits | PI values higher than the specifications were identified in samples obtained in wet and moderate climatic regions. | The PI values of samples obtained in wet and moderate climatic regions generally showed values that met the requirements. |
|
| The plasticity test results of samples obtained in the dry region generally showed values that met the requirements. | The plasticity test results of samples obtained in the dry region generally showed values that met the requirements. |
| XRD (Site A) | Two new minerals were identified in an investigated sample. One of those minerals was a secondary mineral (clinochlore), an alteration product of clinopyroxene; however, it does not have high swell potential. Traces of smectites, an alteration product of pyroxene were identified in both control and investigated samples | Two new minerals were identified in an investigated sample. One of those minerals was a secondary mineral (clinochlore), an alteration product of clinopyroxene; however, it does not have high swell potential. Traces of smectites were identified in the control sample. No Traces of smectites were identified in the investigated sample. |
| XRD (Site B) | Two new minerals were identified in the road sample. One of them was a secondary mineral (chlorite), an alteration product of clinopyroxene. Smectites, an alteration product of pyroxene were identified in both control and investigated samples. | There were new minerals identified. Significant quantities of smectite were evident in the investigated sample. Smectites are an alteration product of pyroxene (and possibly plagioclase) in the form of clay. No signs of smectite identified in the control sample. |
| XRD (Site C) | No signs of alteration identified. | No signs of alteration identified. |
| XRD (Site D) | No signs of alteration. The Secondary minerals detected in the investigation sample were already in the control sample and they do have high swelling potential | No signs of alteration. The Secondary minerals detected in the investigation sample were already in the control sample and they do have high swelling potential. |
