2011 JUN 22 - (VerticalNews.com) -- According to a study from West Lafayette,rnUnited States, "The noise generated when a tire impacts a contraction joint, often called wheelslaprnor joint-slap noise, can increase tire-pavement noise in Portland cement concrete roadwaysrnby up to 3 dB as well as increase annoyance appreciably. Wheel-slap noise has a much higherrnpeak pressure level than tire-pavement noise measured without joints."
