Smoothness Services

Build Smoother Pavement

Pavement smoothness directly affects ride comfort.

The public demands good ride quality, agencies want good pavement smoothness specifications, and contractors want to do the best job possible to lower their bids and/or maximize incentive. Transtec knows the tools and best practices to meet these demands.

Smooth Pavement Design and Construction Services

Some examples of how Transtec experts can help you achieve smooth pavements:

Materials Specifications

The right materials can make smoother pavements, but which ones? Together, we will find the right answer for you.

Design and construction methods for smoother pavements require a careful understanding of the materials specified. Transtec experts understand both pavement materials and pavement smoothness. We can provide superior design and construction recommendations that reduce ownership costs, increase rider comfort, and maximize pavement performance.

Pavement Grinding Optimization for Cost-effective Corrections

We can dramatically reduce diamond grinding costs by simulating the effects of grinding, and identifying how much and where it is necessary.

There is a break-even point with grinding, beyond which it is no longer cost-effective. We can show you where that point is. We can also show you how much improvement in smoothness is obtained from different grinding methods, and from grinding in different locations. The savings in grinding costs is usually far greater than the cost of this service.

Slipform Stringline Staking Optimization before Construction

Closer stringline stakes more accurately represent the paving grade, but also introduce cost and more human error. You can optimize your stringline plan and get a smoother pavement.

With our proven analysis techniques, we can work with you to review your construction plans, and provide stringline stake spacings that can maximize pavement smoothness. This service has created significant interest in the industry as a means to improve pavement smoothness prior to construction.

Smoothness Standards

There are many standards related to road profiling and smoothness.

Transtec can help you interpret standards and verify that requirements in the standards are met. Common specifications include:

AASHTO M 328-10 Standard Specification for Inertial Profiler
AASHTO R 54-10 Standard Practice for Accepting Pavement Ride Quality When Measured Using Inertial profiling Systems
AASHTO R 56-10 Standard Practice for Certification of Inertial Profiling Systems
AASHTO R 57-10 Standard Practice for Operating Inertial Profiling Systems
ASTM E1926-08 Standard Practice for Computing International Roughness Index of Roads from Longitudinal Profile Measurements
