Project Objective

To establish a relationship between the concrete Durability Factor (DF) and various quickly-determined factors of which DF is a function, such as aggregate characteristics, mix proportions, as-delivered w/cm, air content, air void system, and early-age strength.
 

Project Abstract

In response to a MoDOT RFP,MST willestablish a relationship between the concrete Durability Factor (DF) and various quickly-determined factors of which DF is a function, such as aggregate characteristics, mix proportions, as-delivered w/cm, air content, air void system, and early-age strength.

Anticipated Benefits

The results of this project will allow MoDOT engineers to quickly determine when a newly placed concrete pavement may have durability problems so that corrective steps can be taken. The results will provide MST with a knowledge base of concrete and aggregate durability data and testing skills.
