| PROJECT TITLE : | Investigation of Effect of Curling on As-constructed Smoothness and Ride Quality of KDOT PCC Pavements (K-TRAN Project: KSU-01-07) |
| SPONSOR : | Kansas Department of Transportation (KDOT) |
| OBJECTIVE : |
Pavement Roughness/Smoothness can be attributed
to the profile irregularities and their distribution over the measurement
interval. It is an important indicator of pavement riding comfort and safety.
From an auto driver’s point of view, rough roads mean discomfort, decreased
speed, potential damaged vehicle, and increased vehicle operating cost.
A part of roughness comes from curling, which is caused by temperature
and/or moisture gradient between pavement top and bottom. The objective
of this project is to evaluate and quantify curling on the as-constructed
as well as short-term smoothness measurements by KDOT South Dakota Profiler
so that the occurrence of curling could be minimized through modifications
to the design and/or construction practices. The study will help achieve
it’s goal of providing smoother and smoother roads to the public. Since
most the pavement management systems are driven by roughness, the study
would result in millions of dollars in savings in PCCP rehabilitation if
the initial roughness progression could be slowed down.
