 Haul Road Expenditures can pay BIG Dividends... starting TODAY!
Introducing EK35®, the revolutionary NEW patent-pending formulation that can produce hundreds of thousands of dollars in savings by reducing operational costs and increasing asset utilization. EK35® is applied neat to haul road surfaces providing a dual patent-pending mechanism for dust control and soil stabilization. The penetration ability provides a new dust suppressing mechanism, which acts as a durable, reworkable binder. EK35® works well with all aggregate materials and soil types. It effectively stabilizes deep dust and loose surface materials. EK35® applications last longer than other ordinary chemical suppressants, therefore requiring fewer maintenance applications. The surfaces are reworkable. This continuously active suppressant is resistant to rain for long periods of time. EK35® will stop the cycle of roadway deterioration caused by watering, grading, lost aggregate and heavy traffic on mine haul roads. EK35® will preserve fines, increase density and maintain the stability of the surface. Along with the road’s natural crown, EK35® will work to allow better drainage, reducing or greatly eliminating washboarding, potholing and rutting. Midwest Industrial Supply, Inc.’s technical service personnel, using our Samitron® (Stiffness and Modulus Instrument), derive Young’s modulus, shear modulus, CBR and rolling resistance values from in-situ soil stiffness values. These values are obtained using Samitron’s® ability to measure the stress imparted to the surface and the resulting surface velocity as a function of time. |
| We provide general guidelines for estimating and designing the optimum road conditions for higher efficiencies, lower maintenance and fuel consumption.
To stay profitable, mining operations today are investing in greater contamination control. EK35® is the answer by controlling contamination and maintaining high density and compaction on the roadway, which will translate into reduced rolling resistance and improved asset utilization. The EK35® road “pays” for itself with better efficiency, lower vehicle maintenance, and DECREASED O & O COSTS!

On weaker haul road surfaces, the rolling coefficient of friction has an adverse effect on haul truck rolling resistance. Recommended tire pressures may cause shear failures of the surface and deflections in the form of rutting on unstabilized haul road surfaces. These actions extract energy from the wheel motion and cause an increased rolling coefficient of friction. The result is increased O & O costs! Using Samitron® technology and algorithms constructed from testing conducted by the U.S. Corps of Engineers, rolling resistance values can be measured, optimized, and monitored for given haul truck tire pressures.

Life Dust Control/Stabilization
| Much of today’s haul road maintenance involves an intense schedule of around the clock watering and an ongoing program of grading and materials replacement. Many road materials are difficult to wet with water, and water contributes to destabilization and wear of the surface as much as it does to dust control. Dust creates friction that results in wear, which ultimately causes mechanical stress and mechanical failure.
The mechanical drive systems of today’s haul trucks challenge haul roads because of better braking and steering control. As haul trucks travel at higher speeds they challenge haul road design to accept these higher speeds. As haul trucks get wider, haul roads must get wider, which increases haul road maintenance costs. Haul truck utilization must offset increased haul road costs. Road maintenance plays a major role in haulage operations and has a direct influence on truck maintenance costs, road maintenance costs, and owning and operating costs (fuel consumption, tire wear). Our program fits nicely with the high priority of mining companies for improving equipment performance through better operations and maintenance practices and technologies applied to roads. When it can cost between $6,000 and $90,000 to rebuild an engine and anywhere from $5,000 to $50,000 to rebuild a transmission, it makes sense to eliminate the dust as a contributing factor to the friction, wear and failure. An effective haul road maintenance stabilization and dust control program can produce savings from haul truck repair and maintenance. A typical 218 ton haul truck costs approximately $2.5 million dollars, and over the life of that truck, repair and maintenance costs are projected to be another $2.3 million. A road maintenance stabilization and dust control program that controls dust can save as much as $300,000 over the life of each haul truck. Even greater financial benefits are available in reduction of owning and operating costs and improved asset utilization. EK35® maintains the integrity of the road surface through stabilization and fines preservation. A by-product is elimination of dust. The financial benefits are 1) the reduction in haul truck maintenance repairs, 2) lower road maintenance, 3) eliminated watering expenses, 4) a reduction in owning and operating costs, and 5) increased productivity and improved asset utilization.
