A New Design Approach for Mine Haul Road Pavements
Summary: The numerical studies suggest that the current CBR design methods can lead to under-design results, especially for mine haul roads that are used by ultra-large trucks and heavy loads. The new proposed design method with stabilized pavement layers can lead to better design in road structure and smaller strain and displacement. The stiffness change from road stabilization also noticeably ...

Warming rivers endanger aquatic life, research unveils
Rivers across the globe are experiencing unprecedented rates of warming and loss of oxygen, endangering aquatic life. Recent findings from a Penn State-led study reveal that among almost 800 rivers examined, a staggering 87% have been warming, while 70% have been losing oxygen. For areas like the American South, the future could be even bleaker. Projections indicate that within seven decades, ...

Time for a new water management approach in Mexico - Case Study
Ricardo Ontiveros is convinced. After being a customer using Truxor’s amphibious tool carrier he is now set to mission a new way of water management. “The regrowth in the lakes is faster than the maintenance with the current methods. With Truxor we have a possibility to change that to the better”. In the Mexican lakes and water reservoirs the invasive water hyacinth is causing ...

Conserving Natural Resources Using Geosynthetics
Natural resources are finite, or at a minimum, can easily be consumed faster than they can be replaced. As such, the conservation of natural resources is a pragmatic endeavor. Geosynthetics-widely available materials used in construction, civil engineering, and environmental protection-can be useful in promoting the conservation of these resources. When used as intended, geosynthetics can enhance ...

Hydrocarbon-Contaminated Soil Remediation
Hydrocarbons are organic compounds composed of hydrogen and carbon atoms and are the building blocks of many fossil fuels. Petroleum products, such as gasoline, diesel, and oil, are major sources of hydrocarbons. Spills or leaks of these products can result in soil contamination, and if left unaddressed, can have significant environmental and health impacts. In this article, we will discuss the ...
