Abstract
In today’s world pavements play an important role in the development of the Country Permeable paving is a range of sustainable materials and techniques for permeable pavements with a base and sub base that allow the movement of storm water through the surface. In addition to reducing runoff, this effectively traps suspended solids and filters pollutants from the water. Examples include roads, paths, lawns and lots that are subject to light vehicular traffic, such as car/parking lots, cycle-paths, service or emergency access lanes, road and airport shoulders, and residential sidewalks and driveways. Although some porous paving materials appear nearly indistinguishable from nonporous materials, their environmental effects are qualitatively different. Whether pervious concrete, porous asphalt, paving stones or concrete or plastic-based pavers, all these pervious materials allow storm water to percolate and infiltrate the surface areas, traditionally impervious to the soil below. The goal is to control storm water at the source, reduce runoff and improve water quality by filtering pollutants in the substrata layers. The analysis was undertaken by conducting a number of tests on no-fines concrete samples. The tests included both fresh and hardened concrete tests to obtain a complete picture of its properties during the construction and working phase. The tests conducted to determine the fresh concrete properties were the slump, VEBE and compacting factor tests. These were complimented by hardened concrete tests including the following: compressive strength, indirect tensile strength and skid resistance. It was found that no-fines concrete pavements possess some positive features like increased skid resistance and high permeability but lacks the high strength required for highly trafficked areas. No-fines concrete has proven to have properties suitable for use in low volume traffic areas. The properties found may change depending on the aggregate particle chosen, however this aspect requires further investigation. Nonetheless, if no-fines concrete pavements can be implemented, it will have numerous positive effects on the environment.
