A news story in the San Antonio Express News by reporter Jennifer Hiller asks the question Could old tires help fix roads in the Eagle Ford Shale? http://m.mysanantonio.com/business/eagle-ford-energy/article/Could-old-tires-help-fix-roads-in-the-Eagle-Ford-5173275.php
This story is about an ongoing effort by Jeff Labenz-Hough of HDR Engineering San Antonio to use Mechanical Concrete® to solve some of the road problems generated by the oil and gas exploration activity in South Texas. South Texas is looking at Mechanical Concrete®. The answer to the question is yes, old tires can help.

1. Mechanical Concrete®, is a US and Canadian patented sustainable construction technology. Mechanical Concrete® is a geo-cylinder stone aggregate confinement technology. It is a simpler, stronger and more consistent way to build road bases. It’s fully developed and demonstrated in industrial road applications and now in use in 5 US states.
2. Mechanical Concrete® is created by placing crushed stone inside a thin-walled cylinder. Cylindrical confinement dramatically increases the load supporting capacity of granular materials by a factor of 3 or more.
3. Road maintenance is a major challenge for road owners globally and in every state, province and climate and particularly the oil and gas and natural resource industry
4. Mechanical Concrete® offers a virtually indestructible road base that has reduced unpaved road maintenance by 75%. A gravel and concrete surfaced coal haul road near Morgantown WV has been supporting 300 coal trucks per day since June 2011 with a 75% reduction in surface maintenance compared to its original construction. Its primary apps are foundations, retaining walls, and erosion control.
5. Mechanical Concrete® is the same every time and does not require compaction. It’s easy and simple to install and doesn’t requires special equipment, training, or field testing.
6. As its thin-walled cylinder Mechanical Concrete® uses a waste tire with both sidewalls removed. This make it an inherently, bright green building material, and substantially lower in cost than other geosynthetic confinement technologies.
