Description

The NRN product is distributed in the form of thirteen provincial or territorial datasets and consists of two linear entities (Road Segment and Ferry Connection Segment) and three punctual entities (Junction, Blocked Passage, Toll Point) with which is associated a series of descriptive attributes such as, among others: First House Number, Last House Number, Street Name Body, Place Name, Functional Road Class, Pavement Status, Number Of Lanes, Structure Type, Route Number, Route Name, Exit Number. The development of the NRN was realized by means of individual meetings and national workshops with interested data providers from the federal, provincial, territorial and municipal governments. In 2005, the NRN edition 2.0 was alternately adopted by members from the Inter-Agency Committee on Geomatics (IACG) and the Canadian Council on Geomatics (CCOG). The NRN content largely conforms to the ISO 14825 from ISO/TC 204.

Description

This study was undertaken to help improve the safety of snowplow vehicles by enhancing the rear lighting visibility to approaching drivers. This research project conducted field trials testing some of the recent developments in lighting technology. New specifications recommended from this study will help both the department and the maintenance contractors in providing improved lighting for visibility of the snowplow vehicles to motorists.

Description

In 1998, a low-power FM radio broadcast transmitter was installed and tested near Valleyview on Hwy 43, to warn travellers of inclement road and weather conditions and construction or maintenance activities. This Highway Advisory Radio (HAR) broadcast transmitter had a range of eight kilometres. The resulting report recommended that a portable HAR be evaluated on moving construction/ maintenance projects. This project follows up on that recommendation and documents the use of a portable HAR system on six mobile highway construction projects in Alberta.

Description

The cost of installation, maintenance, rehabilitation and operating costs for illuminated overhead sign structures is a concern for several Alberta Infrastructure operations managers. A very high-brightness reflective sheeting material was introduced in 1994 as a possible alternative to illumination. Since then several new products have emerged with a similar claim of superior retro-reflectivity properties when compared to traditional sheeting materials that were used in the past. A demonstration project was developed in order to assess the comparable performance of these materials and determine the minimum sign sheeting requirements for non-illuminated overhead signs. Based on this demonstration it is recommended that the department continue to specify using 3M's Diamond Grade (VIP) series 3990 as a proven product for use on overhead signs and for other specialized signing requirements.

Recycled plastic guardrail posts for use in a flexible, longitudinal roadside (weak post) barrier

Description

Wooden guardrail posts are subject to splitting and rot as they age. Wooden guardrail posts that have been in service between eight and 15 years are evaluated and scheduled for replacement based on their condition and estimated remaining service life. Approximately 20,000 posts are replaced each year. Recycled plastic posts have a conservative service life of 30 years. The objective of this project was to determine if recycled guardrail posts should be accepted for use in the department's standard W-Beam (Weak Post) Unblocked Wood Post, Flexible, Longitudinal Roadside Barrier System.

Description

RejuvaSeal is a product used primarily at airports for jet fuel spill protection and on heavily-oxidized airport pavements to prevent failure due to raveling and minor surface cracking. A demonstration of RejuvaSeal was offered to Alberta Infrastructure in order to assess the technical benefits of RejuvaSeal as a surface preservation treatment. The overall consensus after one winter cycle was that the product performs better than a traditional fog seal. The long-term benefits and performance will vary and is dependent on the severity and extent of the damage already experienced by the asphalt concrete pavement. RejuvaSeal will be included as a proprietary surface treatment option for treating heavily-oxidized asphalt concrete pavement. Additional monitoring is required to determine the service life of this treatment option.

Description

Alberta Infrastructure adapted IRI as its performance measure for reporting pavement condition in 1998 after bench marking the primary highways network in 1996. The IRI is a simple and stable measure of road roughness. The reasons of simplicity and stability led Alberta to switch over to this measure from PQI, which is composed of three pavement condition parameters.
