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.
