Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   This projects aims to provide recommended specifications for┬áthe mechanical properties of lightweight high-performance concrete.┬áRecommendations will be provided to code-writing committees in order to allow for a systematic update of codes to reflect the performance of modern lightweight concrete.
Goals:   The key project objective is to develop recommended specifications for the mechanical properties of lightweight high-performance concrete as relevant to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specification.
Product Type:   Research report
Techbrief
Technical report
Test Methodology:   Approach includes physical testing of multiple lightweight concrete mix designs, compilation of decades worth of lightweight concrete mechanical properties from other research efforts, probabilistic analysis of results, and creation of recommended specification provisions.
Other Information:   Physical mechanical testing conducted alongside full-scale structural tests.
Expected Benefits:   The expected benefit is the facilitation of a major revision of the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specification, thus updating structural concrete provisions to reflect the performance of modern lightweight concretes appropriately.
Deliverables:   National Technical Information Service (NTIS) report providing full results of research project.
