The Triton coastal and waterway systems use innovative composite marine structures made of advanced geogrid and geotextile materials for erosion control and waterway construction projects. The systems include marine mattresses, filter mattresses, gabions, marine cells, and grid composites that can be used for applications like shoreline protection, foundations, channel linings, and bridge construction. Triton systems offer advantages over traditional materials like riprap in that they are durable, flexible, resistant to chemical and environmental degradation, and can use locally available fill materials, making them a cost-effective solution to coastal erosion and waterway issues.

At the California Asphalt Pavement Association (CalAPA) Fall Asphalt Pavement Conference held Oct. 27, 2022 in Sacramento, a presentation titled "Use of Recycled Materials in Seal Coat Systems" was delivered by Doug Ford, President – Pavement Coatings.
Extending the life of your pavements, and your pavement dollars, means protecting your investment. Today we also include the sustainability of the strategies that are used to preserve our pavements. This session will cover the use of RAP in slurry seals and chip seals. Understand the benefits, constructability and performance of these tools.
A presentation on the Dry Stack Tailings design associated with the Rosemont Copper Project developed by the AMEC Consulting Company. This presentation was given to the Forest Service and their contractors during technical transfer meetings in November 2008.
This document discusses sustainability in road construction. It notes that road construction requires large amounts of materials like aggregates and fuel for transportation and production, which causes high energy consumption and emissions. It also causes issues with waste generation from old pavements. The document then discusses different techniques for pavement maintenance and rehabilitation like reconstruction, overlaying, and recycling. It focuses on full depth recycling (FDR) techniques, providing details on the suitability of roads, types of binders used, the construction process, and mix design process for FDR using cement or bitumen stabilization. FDR can help reduce material consumption and waste generation compared to other techniques.
The document discusses various methods for controlling water production in oil wells. It begins by explaining the reasons water control is important and outlines different water types. It then describes potential mechanical, physical, and chemical solutions for shutting off water sources. These include tools like packers and bridge plugs, materials like cement and sand plugs, and chemicals like polymer gels and resins. The document emphasizes the importance of proper well diagnostics to identify the specific water problem before selecting the most appropriate water control solution.
The document discusses sewage treatment processes. It describes compact sewage treatment plants that occupy minimum space and have low operation and maintenance costs. These plants require less manpower and do not cause odor nuisance. They also allow for future expansion and minimal sludge handling. The document then discusses various sewage treatment technologies and their advantages, including fluidized bed reactors which have very low area requirements compared to other processes and allow for efficient treatment.
Savanah Mining Equipment provides information on sluices and their design and application. Sluices are containers that use water flow and riffles to separate heavy minerals from ore through gravitational settling. They take the form of inclined troughs with riffles. Key design considerations include feed material properties, treatment parameters, width proportional to throughput, water supply, and slope depending on feed size. A sample design for a small scale 25 cubic meter per hour operation is presented with dimensions and water requirements. Sluices remain useful for artisanal miners due to their low cost and ability to be stored efficiently between seasons.
The document discusses Hevi Sand, a processed chromite product created by AMCOL. It begins with an overview of AMCOL and its global mining operations. It then discusses the traditional chrome ore supply chain and issues with traditional processing methods. The document outlines the development of the H.S. Process for processing chromite, including identifying customer needs, researching chromite formation and impurities, developing plant requirements, and addressing issues like yield and quality. It provides details on the H.S. process plant, technology used, and end product results and issues identified.
5. Problems Associated with
Erosion
• On-Site
Loss of precious topsoil
Instability of structures due to undermining
Regrading and reseeding site
• Off-Site
Sediment Migration from site
Choking and filling of lakes, streams and waterways
Degrades Aquatic habitat
Buries critical spawning gravel and fish eggs
26. Where and Why Use Temporary
Degradable RECPs
• Anywhere land disturbing activities will take place
where erosive forces exceed the limits of
conventional vegetation establishment methods
- Use where mulches
&
blown straw fail

29. Why Use Vegetation?
• Low cost
• Ease of use
• Extremely effective
• Aesthetic
• Easy to maintain
• Habitat benefits
• Public demand
30. How ECBs Work
• ECBs provide erosion protection
prior to vegetation establishment
– Reduce runoff velocity and
volume (improve infiltration of
water)
– Reduce soil detachment and
transportation
– Absorb raindrop energy
– Trap soil particles
31. Additional Benefits Of ECBs
• Organic matrix materials provide
mulching action to enhance
vegetation establishment
– Moisture absorption and retention
– Reduces soil temperature
fluctuation
– Physically supports young plants
47. HISTORICAL USE
• Original product for this application
was hay bales or rock dams
• More recently, synthetic berms
have been introduced to
accomplish this task
48. GeoRidge Features
• Length: 1 metre
• Height: 230 mm
• Inside width: 270 mm
• Weight: 1 kilogram
49. GeoRidge Function
• Reduces water velocity
• Causes soil & sediment to drop out
• Allows for establishment of vegetation

54. Spacing
• Height of GeoRidge/slope in per cent
• 2% slope
– 0.23 m / .02 = 11.5 metre spacing
• 6% slope
– 0.23 m /.06 = 3.8 metre spacing

107. How TRMs Work
Phase 1 - Pre-emergence
• Unvegetated TRM provides primary protection for
seed and bare soil.
• Randomly oriented fibers provide barrier for soil
and seedbed from erosive forces
111. Phase III
Mature Vegetation
•Fully Vegetated; Vegetation provides primary erosion protection
while TRM provides supplemental erosion control and vegetation
reinforcement (Occurs 6-36 months after installation).
•The permanent structures in the Vmax products reinforces the
vegetation and provides supplemental erosion control to protect
the soil from shear forces penetrating the vegetative cover
