In using cement as a stabilizing agent in Gravelpave2, location and application need to be considered in order to determine delivery method. Small, remote projects like rails to trails installations or horse trails where larger vehicle access is limited will require a small portable cement mixer and wheel barrow conveyance. Cement is added to stone proportionately, say one shovel full for every ten shovels full of stones. Dye may be added here also, as in the Garden of the Gods project, one 8 oz. full for every 1/3 of a yard mixed. For larger, more accessible jobs, a ready-mix concrete truck can be used, preferably a front discharge truck, which can save labor by spreading the mix over the Gravelpave2 fairly evenly, prior to raking and tamping. IN BOTH CASES NO WATER IS ADDED TO THE MIXES; THE STONE AND CEMENT ARE SPREAD AND TAMPED DRY INTO GRAVELPAVE2. (Note: ready-mix trucks must either be relatively new or have well-maintained, sharp augurs in order to allow the dry product to pour freely. You will need to mention this to the ready mix dispatcher.)

  • Rake In Greater Capacity And Higher Hay Quality

    It’s been said that the steel-toothed dump rake was first introduced in the 1860s. Of course, the process back then was to rake hay into piles, which were then pitched onto a wagon for transport to a haystack or the barn loft. To make windrows for the balers that came later, the operator simply spaced the “dumps” equally so they lined up in the field. The irony is that until they recently purchased a Vermeer VR2040 High-Capacity Wheel Rake, Butch and Matt McGinn, who own a ranch between Anselmo...

  • Hydrochemical and multivariate analysis of groundwater quality in the northwest of Sinai, Egypt

    The northwestern coast of Sinai is home to many economic activities and development programs, thus evaluation of the potentiality and vulnerability of water resources is important. The present work has been conducted on the groundwater resources of this area for describing the major features of groundwater quality and the principal factors that control salinity evolution. The major ionic content of 39 groundwater samples collected from the Quaternary aquifer shows high coefficients of variation reflecting asymmetry...

  • What’s Living in “Bourbon Gumbo” Street Water?

    Bourbon Street in New Orleans frequently has stagnant water sitting along the curbs at all hours of the day rain or shine. This phenomenon is somewhat unusual and is likely due to inadequate drainage as the street is more than 100 years old and doesn’t slope adequately in many places. Due to the nature and atmosphere of Bourbon Street it begs the question of what exactly is in that water. Some locals refer to this water as “Bourbon Gumbo.” Microbe Detectives decided to investigate. We were told...

  • Non-carcinogenic risk assessment of groundwater in South Gobi, Mongolia

    Thirty-nine groundwater samples were collected from wells near the Tavan Tolgoi and Oyu Tolgoi mines in Mongolia and at a relatively pristine site in northern Mongolia during August to September 2013, and analyzed for the concentrations of F−, NO3−, Hg, As, Al, V, Mn, Co, Ni, Cu, Zn, Se, Mo, Cd, Sb, and Pb. A probabilistic risk assessment found that >95% of the population in the areas was at risk from drinking well water. The hazard index (HI) was >1, indicating a non-carcinogenic risk to human health. At...
