What are small to medium sized mole-hill type projections from the pavement surface called?

The correct term for small to medium-sized mole-hill type projections from the pavement surface is "blisters or upheavals." This terminology specifically refers to deformities that manifest as raised areas on the surface, often caused by moisture trapped beneath the pavement or other factors that lead to compaction issues or air pockets within the asphalt layers. Understanding this term is essential because it helps inspectors identify potential failures in the asphalt pavement that could lead to more severe issues if not addressed.

While other options describe different pavement defects or phenomena, they do not accurately represent the specific condition indicated in the question. For example, "bleeding or slurping" typically refers to the occurrence of asphalt binder surfacing due to excessive heat or moisture, while "pushing or shoving" describes the lateral displacement of pavement under load, particularly in the presence of shear forces. Each of these terms has its own specific conceptual framework, making it important to use the correct terminology in pavement inspections for clarity and effective communication.
