The weathering of pyritic mudrocks can have serious consequences for construction, and in particular for earthworks. Prediction of the likely behaviour of pyritic mudrocks involved in earthworks tends to be overlooked, with only the determination of aggressivity to steel and cementitious materials carried out. British Jurassic mudrocks tend to be soil-like overconsolidated deposits, typically ...

The quality of crushed stone aggregates influences the durability and performance of pavement and concrete as they are the dominant component in the mix. Hence, the selection of a suitable quarry site with the quality source material is essential. Since the quarry site suitability assessment involves various factors, it is more economical to follow a stage-wise suitability assessment …

2) Aggregate layer compaction; and 3) Loading. Specifically, a crushed limestone having low plasticity fines and compacted to 95% of the maximum laboratory density was identified as a best practice and can be used at thicknesses less than the current design recommendations. However, uncrushed gravel and reclaimed asphalt pavement performed poorly.
Limestone, dolomite, and marble - the carbonate rocks - are the principal karst-forming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (fi g.
