Understanding Durability Problems with Dolerite in Roads in …
Dolerite is one of the most widely used road pavement construction materials in South Africa and is classified as a basic crystalline rock. The variable performance of road pavements constructed with such rocks in South Africa has frequently been linked to the durability of the freshly crushed dolerite which can undergo rapid deterioration in service.
Thickness matters: Influence of dolerite sills on the …
Dolerite sills significantly affect the rank, properties and thermal maturity of coals in the CBM play in Botswana. We built 1D thermal maturity models (calibrated with measured VR values of coals) for nine coreholes and investigated the thermal influence of 1 to 73-m-thick sills on sediments above and below the sills. We found that:
