Full-scale laboratory tests of geosynthetic reinforced unpaved roads on a soft subgrade

In this paper, a 15 kVA soft open point converter is presented. The converter design and manufacturing have been presented in previous papers. The aim of this paper was to show the results of the devices in a full-scale laboratory environment, Gridlab, made of four distribution LV feeders, each rated 40 A. The tests demonstrated the good dynamics of the SOP control and its usefulness in performing a suitable PQ control. They also showed an improvement in the voltage profile and in the load capacity of the overall network. In the final part of the paper, the feedback earned during the development and the test of this first prototype are presented. This feedback will benefit the team for the design of a new improved 50 kVA version.

Highway Research

In 1992, FHWA initiated a Superpave validation study by utilizing the Accelerated Loading Facility (ALF) at the Turner-Fairbank Highway Research Center in McLean, Virginia. The study focused on the validation of the concepts, tests, and predictive models underlying the Superpave binder specifications and mixture analysis system. Twelve full-scale pavement lanes with 48 test sites were constructed at the FHWA Pavement Testing Facility in 1993. Pavement testing with the ALF started in late spring of 1994. The results of accelerated full-scale pavement tests in conjunction with extensive laboratory tests will be used to validate the Superpave binder parameters for rutting and fatigue cracking. Presented in this paper are the results of rutting tests and some of the data analysis completed through June 1997.

ABSTRACT The Minerals Management Service (MMS), U.S. Department of the Interior, operates a wave tank facility in Leonardo, New Jersey known as OHMSETT (Oil and Hazardous Material Simulated Environmental Test Tank), which is used primarily for testing oil spill booms and skimmers. This paper summarizes two studies undertaken to examine the feasibility of testing dispersants at the facility as well. The first study included: (1) interfacial tension laboratory tests, (2) turbidity tests, (3) laboratory tests to evaluate filtering materials for removing dispersant and chemically dispersed oil, and (4) full-scale evaluation testing at OHMSETT. The results indicated that dispersant testing at OHMSETT could be done with good success if the testing program were carefully designed and implemented. It was determined that a number of dispersant tests could be conducted over several days, after which the tank water would have to thoroughly cleaned to remove dispersed oil (with a cellulose-based filter) and dispersant (with an activated carbon system). Following the feasibility study, the project moved to the second study, namely the design and validation of an experimental protocol for dispersant effectiveness testing at the facility. Full-scale tank work was conducted in April 2000. Preliminary results, provided in this paper, indicate that OHMSETT is an attractive facility for determining dispersant effectiveness.
