Geosynthetics for Roadway Construction

Geosynthetics for Roadway Construction

Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

The ability to categorize suspended sediment metrics (e.g., total concentration, mean particle size, particle size class) to specific land-use types is increasingly appealing in terms of better targeting mitigation strategies. However, innovative real-time in situ instruments that advance monitoring capabilities often provide results that are not readily comparable to traditional

Recent American Water Works Association (AWWA) studies conclude that America is currently in an era of pipe replacement, points out Lawyer Jolley, general manager of Performance Pipe, a division of Chevron Phillips Chemical Company.

Keeping Them Alive

Keeping Them Alive

No contractor wants to make headlines because of a trench collapse. When a collapse results in the death of a laborer? That’s tragic, and the resulting fines and lawsuits could be enough to put even large contractors out of business.

But it doesn’t take a fatality for contractors to suffer a serious hit on

OSHA and the Competent Person

OSHA and the Competent Person

OSHA officials have long recognized the potential danger that employees face when doing trenching or excavation work. That’s why OSHA requires that a competent person be onsite when construction crews are doing this kind of work.

According to the OSHA Construction Standard, a work site’s competent person must be capable of identifying existing
