  Introduction to PavementDesigner.org - Brian Killingsworth, P. E.,  NRMCA

Learn about the concrete industry's newest pavement thickness design tool. The PavementDesigner.org website is a free tool for designing parking lots, streets and industrial facilities using conventional concrete, roller compacted concrete, concrete overlays, and full-depth reclamation. Brian Killingsworth, P.E., NRMCA's Executive Vice President for Local Paving will lead the seminar providing background on the website and demonstrating its capabilities.

This 90-minute presentation will detail the pavement design platform and reveal other important features of the website. The session also will include a design demonstration for streets & roads, parking lots/areas and intermodal pavements. The session is intended for concrete industry representatives, design engineers, and public officials.

CLSM Flowable Fill - Brian Killingsworth, P. E., National Ready Mixed Concrete Association

Flowable fill was initially developed over 20 years ago as a solution to reoccurring problems originating from poorly compacted soil or granular fill. The versatile "liquid soil" which is placed as a flowable liquid, yet hardens and rapidly develops excellent load-bearing properties with no compaction necessary.

Petrography of Concrete - Bobby Bullard, Ash Grove Cement Company

Petrography is a branch of geology that is applied to concrete and concrete raw materials. This technique examines and evaluates the optical properties and microstructural characteristics of the materials. Petrographic analysis for concrete begins by accepting an aggregate for use in concrete (ASTM C295). Once the concrete is hardened, a petrographic examination that follows American Society for Testing and Materials (ASTM) C856 and ASTM C457 can be applied to verify that the product was mixed as designed and that the appropriate or specified materials were used.

Concrete petrography also helps to identify the nature of deterioration or defects, to determine the degree of damage, and to evaluate whether the damage will continue. Perhaps most critically, petrographic analyses aid repair versus replace decisions, making them an integral part of evaluation strategies.
