Concrete Mixtures that Incorporate Inclusions to Reduce the Sound Generated in Portland Cement Concrete Pavements
Tire-pavement interaction noise is one of the significant environmental problem in highly populated urban areas situated near busy highways. Traditionally, this problem was reduced through the use of sound barriers; but this method has limitations. The understanding that methodologies to reduce the sound at the source itself is necessary, has led to the development of modified cement concrete materials. This report outlines the systematic research effort conducted in order to develop and characterize two different cement based materials incorporating inclusions. Morphologically altered cellulose fibers were used in the first part of this study as inclusion materials in a plain cement mortar matrix. Flexible polypropylene fibers were used as inclusions in a porous concrete (gap-graded aggregate concrete) matrix in the second part.
