The Durable Performance of Perpetual Pavements
When the Iowa Department of Transportation (IDOT) opened a new stretch of U.S. Highway 151 in Linn County back in 1966, they wanted a road that would last a long time, but they never imagined the traffic loads and heavy-weight trucks that drive on U.S. highways today. Despite this, U.S. 151 is still in place and in […]

The Durability Factor
The goal is performance over time.
August 7, 2013
Mechanistic-empirical pavement design considers site conditions such as traffic, climate, subgrade, existing pavement condition for rehabilitation, and construction conditions, in proposing a trial design for a new pavement or rehab; then, using software, the trial design is evaluated through prediction of key distresses and smoothness.

Perpetual Pavement an Inch at a Time
Perpetual pavement can be applied to lower-volume roads or to rehabilitations of thinner pavements.
December 1, 2012
Layer on Layer: Adding asphalt layers as thick as a quarter can be a sound way to manage secondary road. By adding one inch of asphalt, you can reduce the aggregate base requirement by about four inches or more, offsetting the increased cost of the additional asphalt. Furthermore, thinner aggregate bases require less excavation, yielding even more savings.
