Smoothness Specification Update

Florida Department of TRANSPORTATION Smoothness Specification Update 38 th Annual Asphalt Conference September 9, 2014

Intents Separate Rolling Straightedge from Laser Profiler Create Ride Quality (Smoothness) Incentive/Disincentive Specification Based on 6 years of project data Use International Roughness Index (IRI)

International Roughness Index (IRI) Vertical movement per length traveled Measured in inches per mile Lower is Smoother IRI data obtained by Laser Profiler Pilot projects use SMO laser profiler vans Incentive/Disincentive $ based on IRI data Pay for Smoothness / Penalize Roughness

Incentive/Disincentive IRI Ranges IRI Pay Result 30-42 +$20 per IRI point per 0.1 mile LOT 43-55 Full Pay 56-95 -$ 20 per IRI point per 0.1 mile LOT >95 Remove & Replace*

Areas Unsuitable for Laser Profiler Testing Use RSE or Manual (Rigid) Straightedge per 330 Specs R&R or Pay Reductions per current Specs

Last Structural Lift SMO will collect IRI data on Last Structural Lift Contractor Request Let s contractor know where they stand prior to paving friction course Contractor make more informed decisions on questionable pavement
