Evaluation of HPC Pavement in Nelsonville, Ohio, using Non-destructive Methods

Abstract

This paper is focused on evaluating the performance of several concrete mixes of high-performance concrete (HPC) pavement using different techniques such as laboratory testing, warping and curling monitoring and falling weight deflectometer testing. A research plan was developed to accomplish two principal objectives: First, to determine the maturity function of the newly placed concrete, and second, to monitor dynamic and environmental response of concrete slabs in each of three test sections. Each test section was approximately 1,000 feet long. Five hundred feet of each test section were cured using a spray-on membrane, while the other five hundred feet were cured using wet burlap. Three Concrete mixes using different types and sizes of coarse aggregate and granulated blast furnace slag were incorporated into this project. Two slabs in each test section were instrumented with thermocouple sticks at the center and outside corners.
