Evaluation of Cleaning Methods of Pervious Concrete Pavement
Pervious concrete pavements are designed to allow rain water to percolate through the pavement voids and reduce runoff water and splashing. One of the problems of pervious pavements is clogging. This study evaluated pervious pavements cleaning methods and presents findings from a study conducted on a fourteen-year old pervious concrete parking lot. For this study, cores were taken from the existing pervious concrete parking lot, and the falling head test was performed on the samples: as cored, swept, and pressure washed. Sweeping removed little debris from the surface, but did significantly increase the infiltration. Pressure washing removed a relatively significant amount of debris from the samples, and also significantly increased the infiltration rates. The samples were then broken to determine remaining debris, since pressure washing did not completely remove all debris from the samples. The properties of the debris were compared to the lawn/garden soil around using sieve analysis, cohesion tests, and organics analysis. From The sieve analysis test, the debris was of a similar gradation to the garden soils; however, a presence of particles from the existing asphalt pavement was observed. A cohesion test revealed that cohesion in the removed debris was less than that of the garden soil around. An organics analysis indicated that organic matter in the debris was less than the organic matter in the garden soils. The study found out that pressure washing is more effective cleaning method on pervious pavements and the clogging materials are soils rather that organics matter.
