Developing Non-skid Road Surfaces
In the second direction, accompanying this outdoor ex posure, will be the standard laboratory tests on these same materials after they have been subjected to freezing and thaw ing, wetting and drying. Such laboratory work will, when compared to the outdoor experiment, tell us whether or not it is necessary to go through the actual construction of a test road in order to find out what may othe...
متن کاملPlant Species Recovery on a Compacted Skid Road
This study was executed to determine the plant species of herbaceous cover in a skid road subjected to soil compaction due to timber skidding in a beech (Fagus orientalis Lipsky.) stand. Our previous studies have shown that ground based timber skidding destroys the soils extremely, and degradations on ecosystem because of the timber skidding limit recovery and growth of plant cover on skid road...
متن کاملLearning the Forward Predictive Model for an Off-Road Skid-Steer Vehicle
A forward predictive model is used to simulate a vehicle's motion given a sequence of commands that could potentially be executed. Generally, forward predictive models are used by planning systems for Unmanned Ground Vehicles (UGV's) so that commands can be selected such that obstacles are avoided. This report presents a data-driven approach for learning a forward predictive model based on prev...
متن کاملPortrait of an optimist
I come from a family of lawyers. When I was growing up, the only scientist in the family was my uncle, who was a physicist. But I was interested in science, and as a boy collected rocks and kept my “chemistry cabinet” in a spare room at my father’s law firm in Rome where I smelled up the place from time to time with failed experiments. When I finished high school at the Liceo Classico Torquato ...
متن کاملEnhancing Skid Resistance of Two-Component Road Marking Paint using Mineral and Recycled Materials
Low skid resistance of road marking paint is one of the major issues in the safety of vehicle drivers, cyclists, and pedestrians when traveling on the city streets. Among the variety of marking paint, two-component paint is widely used at intersections and roundabouts. Therefore, the paint used should have adequate skid resistance. The object of this study was to evaluat...
