1 Quieter Pavement in Washington Mia Waters Washington State Department of Transportation TRB ADC40, Transportation Related Noise & Vibration Williamsburg, VA July 12, 2006

2 What are we testing for? Pavement – twice per year (before & after winter driving season)  Smoothness  Cracking/Raveling  Longevity/Durability  Cost/Benefit Noise – monthly as appropriate for 1 st year (reassess frequency w/in the year)  Tire/Pavement with Onboard Sound Intensity  Resident experience with Wayside/Pass-by  Driver experience with in-vehicle meter

3 What to watch in Washington…  Studded tires  Ground temperatures for installation of open graded rubberized asphalt  Freeze/thaw for trapped water in open graded asphalt  Tire pressures on air pockets for open graded asphalt  Plugging/vacuuming  Heavy traffic wear  Changes to water run-off

4 Asphalt Related Quieter Pavement Test Sections in Washington State (2006) RoadwayProject Location Test Section Comparisons Existing Pavement Type Expected Knowledge Gained I 90Argonne Rd to Sullivan Rd (Spokane) Constructed in 2004  Carpet drag  Transverse tining New concreteNoise and pavement durability in lower volume traffic with high studded tire use. I 5Federal Way to 317th Street HOV Direct Access Constructed in 2005  Carpet drag  Transverse tining New concreteNoise and pavement durability in high traffic environment. I 5Pierce County Line to Tukwila Constructed in 2006  Carpet drag  Longitudinal tining  Transverse tining New concreteNoise and pavement durability in high traffic environment. I 552 nd Avenue West to SR-526 (southbound only) “Lynnwood Test Section” Construction in 2006  OGFC-AR (~¾ mile)  OGFC-SBS (~¾ mile)  HMA (remaining project length) Hot mix asphalt pavement Noise and pavement durability of two types of asphalt quieter pavement compared to standard asphalt in high traffic environment (including truck traffic).

5 RoadwayProject Location Test Section Comparisons Existing Pavement Type Expected Knowledge Gained SR 520Test section location to be determined (east and west bound) Construction in 2007  OGFC-AR (~¾ mile)  OGFC-SBS (~¾ mile)  HMA (~¾ mile) Hot mix asphalt pavement Noise and pavement durability of two types of asphalt quieter pavement compared to standard asphalt for wayside homes because it covers both directions of traffic. I th Avenue SE to SE 8 th Street (north and south bound) Construction in  OGFC-AR (~1 mile)  OGFC-SBS (~1 mile)  HMA (~1 mile)  Diamond ground concrete Hot mix asphalt and concrete pavement Pavement durability of two types of asphalt quieter pavement overlaid on concrete pavement and noise durability of a diamond ground concrete surface Asphalt Related Quieter Pavement Test Sections in Washington State (2006)
