TRAINING LEVEL: Intermediate

CLASS SIZE: Minimum: 1 Maximum: 1

COURSE DESCRIPTION:

This training was prepared by the Transportation Curriculum Coordination Council (TCCC) in partnership with NHI to provide guidance on critical concrete pavement preservation issues. The training was developed by the National Concrete Pavement Technology Center at Iowa State University in cooperation with FHWA.

This module presents design and construction information on load transfer restoration (LTR), sometimes referred to as retrofitted load transfer. In the introduction we will describe the difference between load transfer restoration (generic term) and dowel bar retrofitting (DBR) which is a specific means of achieving LTR. There are other methods available, but DBR is the most proven.

This module is part of the curriculum from the Concrete Pavement Preservation Series (FHWA-NHI-131126) which presents current guidelines and recommendations for the design, construction, and selection of cost-effective concrete pavement preservation strategies. The other Web-based training modules are:

- NHI-131126 Concrete Pavement Preservation Series with downloadable version of the FHWA Concrete Pavement Preservation Guide

- NHI-131126A: Pavement Preservation Concepts

- NHI-131126B: Concrete Pavement Evaluation

- NHI-131126C: Slab Stabilization

- NHI-131126D: Partial-depth Repairs

- NHI-131126E: Full-depth Repairs

- NHI-131126F: Retrofitted Edge Drains

- NHI-131126G: Dowel Bar Retrofit

- NHI-131126H: Diamond Grinding and Grooving

- NHI-131126I: Joint Resealing and Crack Sealing

- NHI-131126J: Concrete Overlays

- NHI-131126K: Strategy Selection

OUTCOMES:

Upon completion of the course, participants will be able to:

  • List benefits and applications of load transfer restoration
  • Describe recommended materials and mixtures
  • Describe recommended construction procedures
  • Identify typical construction problems and remedies

TARGET AUDIENCE:

The intended audience is quite diverse, and includes design engineers, quality control personnel, contractors, suppliers, technicians, and trades people. While the course is aimed at those who have some familiarity with concrete pavements and pavement preservation, it should also be of value to those that are new to the field. This course is recommended for the Transportation Curriculum Coordination Council levels I - IV.
