Iowa's Pavement Preservation Guide

Selecting the right treatment for the right pavement at the right time has been a fundamental principle to pavement preservation success (Galehouse et al. 2003). The objective of this project is to develop “Iowa’s Pavement Preservation Guide”, a document tailored to serving the needs of Iowa practitioners who have active pavement preservation programs or plan to implement a pavement preservation program. This proposal outlines a research approach based on national-best practices for pavement preservation program implementation. The research addresses six areas including: (1) project selection, (2) anticipated benefit/costs of pavement preservation treatments at the network- and project-level, (3) implementing pavement preservation into system-wide strategic planning, (4) preservation treatment considerations, (5) construction/specifications, and (6) materials training. Many states have developed pavement preservation manuals. These manuals show it is important for pavement preservation guidance to include project-level and system-level selection strategies because project-level decisions have a network-wide impact. Practitioners using this guidance will be able to communicate pavement preservation benefits at the project- and network-levels, identify candidate roadways for preservation treatments, and utilize the guide to enhance project delivery of pavement preservation treatments.

  • Supplemental Notes:
    • The primary objective of this project is to create a stand-alone document titled, “Iowa’s Pavement Preservation Guide”. The guide will summarize proven pavement preservation techniques for HMA and PCC pavements in Iowa. This project will build on past Iowa pavement preservation research, past Iowa research in asset management, and summarize best practices from sources across the country.
