Pavement Design Manual

This Manual provides a comprehensive guideline to be followed by engineering consultants for pavement design for new roadway and final stage pavement construction, including reconstruction and widening, and rehabilitation. Engineering consultants are responsible for the surfacing strategy and detailed structural pavement design on roadway design project assignments. For the purposes of this Manual, pavement refers to all layers of the pavement structure above the subgrade. An objective of the Manual is to ensure a degree of consistency in designs provided by engineering consultants by following specific structural design methodologies within a general framework. At the same time the design process provides sufficient flexibility to allow for the judgement and innovation by experienced pavement design engineers to address the specific conditions of each project.
Alberta Transportation and Utilities (AT&U) will continue to be the custodian of all pavement evaluation, management and inventory data. These data will be available for use by engineering consultants. AT&U=s role in the design process will be to review pavement designs provided by consultants for completeness, conformance to the design philosophies and methodologies outlined in the Manual, and to ensure that the design is supported by appropriate engineering investigation and evaluation.

Design of Bridge Deck Drainage

The manual provides guidelines and procedures for designing bridge deck drainage systems, including illustrative examples. It includes design theory, step-by-step design procedures, and illustrative examples. Drainage system design is approached from the viewpoints of hydraulic capacity, traffic safety, structural integrity, practical maintenance, and architectural aesthetics. System hardware components, such as inlets, pipes, and downspouts, are described. Guidance for selecting a design gutter spread and flood frequency are provided. System details and existing computer models are discussed.

DURABILITY GUIDELINES FOR THE DESIGN, CONSTRUCTION, REPAIR AND MAINTENANCE OF PARKING STRUCTURES

This project on Parking Structures Durability Guidelines was proposed by Technology Development and Demonstration and was funded by the Real Property Program and the Panel on Energy Research and Development (PERD). This research was conducted in collaboration with Halsall Associates Limited. The objective of this project was to develop specific guidelines for the design, construction, repair and maintenance of parking structures.
Every year, Public Works & Government Services Canada (PWGSC) spends vast sums of money on the repair and maintenance of parking structures. While it is generally accepted that a certain degree of garage maintenance is inevitable, the design and construction practices in past failed to provide adequate protection against the increasing amounts of chloride based de-icing chemicals which are being used in present in-service environments. The salts carried into garages by cars migrate through the concrete to the steel resulting in corrosion of the embedded steel components.
For the past five years, Technology, A&ES Services, Headquarters, in conjunction with the Institute for Research in Construction (IRC) at National Research Council Canada (NRC), have been monitoring the performance of several parking garage structures and evaluating various repair strategies in an attempt to develop techniques for effective rehabilitation and maintenance of indoor parking garages. Much of the knowledge gained from this multiyear research study was used in the development of these guidelines. This document will serve as a very useful tool for builders, operators and property managers. However, it must be emphasized that decisions in design, construction, repair and maintenance must be the responsibility of qualified professionals. If proper procedures are followed, the life of parking garages will be greatly enhanced.
