Assessment of Improved Pulverizer Technology
The objective of this project is the assessment of pulverizer technology using the CMI/Terex RS-325 Roto-Mixer for the construction of contingency semi-prepared airfields for C-130 and C-17 military aircraft. This machine is utilized as a Reclaimer/Stabilizer (commonly known as the Pulverizer machine) to provide soil stabilization through pulverization, and injection of water and polymer emulsions to the soil for the construction of roads and airfield pavement structures. This project is part of the Joint Rapid Airfield Construction (JRAC) program. JRAC has several technologies that are currently under investigation, and new research is being developed every day. The military engineers have to be able to meet the Soldier needs of rapidly selecting, stabilizing, and constructing contingency airfields in severe environments. These airfields will be constructed with equipment that must be transportable via the C-130 aircraft. The RS-325 pulverizer was used during the 2004 JRAC demonstration in Ft. Bragg, NC to construct contingency airfields for the C-130 aircraft in a time frame of 96 hours with state of the art equipment. This research project involves the assessment of the pulverizer technology using the RS-325 for the construction of contingency airfields for the C-17 aircraft. This research also involved the construction of a test section to evaluate the performance and mixing requirements of the RS-325 pulverizer. The test section provided an evaluation of the mixing properties at different depths with fibers, liquid polymers, and Portland cement (Type III). This will allow to monitor, quantify, and optimize the mixing and stabilizing process using the RS-325 at different speeds and application rates in silty sand (SM) soils. The pulverizer will be mixing the top 10–12 in (25.4–30.5 cm) of blended SM material, to simulate the stabilization conditions for a C-17 aircraft. Several challenges in this project were identifying when the pulverizer had properly mixed the total amount of stabilizers with the SM material, developing new measurement techniques to determine the mixing efficiency and stabilizer content from three different depth locations. This paper will include the construction details of the test section, and data collection findings as well as some recommendations for the use of the pulverizer machine. The RS-325 pulverizer was the only pulverizer mixer that fit into a C-130 aircraft without waivers, therefore the only pulverizer that was evaluated in support of the JRAC research.
