What is 30-Year Evaluation of Two-Layer Concrete Pavement about?

This document summarizes a 30-year performance evaluation of an experimental two-layer concrete pavement system in Florida. The experimental pavement included a thin layer of Portland cement concrete over a thicker layer of lean concrete (econocrete) placed on either a granular or cement-treated subbase. After 30 years, the sections built on a granular subbase performed better with minimal distresses, while the control section on a cement-treated subbase experienced greater cracking and spalling.
