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 ...

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 ...

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 ...

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 ...

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, ...

We define amplitude, when referring to vibratory asphalt compactors, as the distance the drum moves into the mat. The weight of the drum, combined with drum movement, delivers impact force into the ...

Designed for use on granular materials and all types of asphalt-mix designs, the CW16 pneumatic roller is available as a standard nine-wheel model with a 69-inch compaction width or as an optional ...
