When you look at the walk-behind compactors in your fleet, chances are you don't think of them as precise scientific instruments. Yet, soil compaction is a science and it requires a certain degree of ...

Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous ...

Asphalt is considered granular due to its base of mixed aggregate sizes (crushed stone, gravel, sand and fines) mixed with bitumen binder (asphalt cement). Consequently, asphalt must be compacted with ...

A new and rapid way to pack identical cubes in a dense configuration has been discovered by physicists in Spain and Mexico. Their work offers new insights into granular compaction and could lead to ...

Summary: The main goal of this project is to investigate how the use of compacted granular columns (CGC) may help improve the seismic performance of embankments on potentially liquefiable soils. First ...

Characterizing forces on deformable objects intruding into sand and soil requires understanding the solid- and fluid-like responses of such substrates and their effect on the state of the object. The ...

When thinking of a small construction company, one typically conjures up the image of an upstart, one- or two-person operation struggling to achieve a steady queue of jobs and working hard to build a ...

Fine powders and granular materials are extensively used in industrial applications. To manage and to enhance processing techniques, these materials have to be exactly characterized. The ...

To regulate and to optimize processing methods, granular materials and fine powders must be precisely characterized for industrial applications. These methods relate to granulometry, morphology, ...
