Description

A proposal by Environment Canada to mandate a maximum Volatile Organic Compound (VOC) content for traffic markings prompted Alberta Transportation to investigate new paint formulations. The purpose of this evaluation was to determine the effectiveness of six low-temperature, low-VOC traffic paint formulations during cold weather application.

Description

Traffic markings used in Alberta consist primarily of alkyd and waterborne paint. Supplemental delineation such as Snowplowable Raised Pavement Markers (SRPM) may improve driver preview distances at night and in adverse weather conditions in high collision rate areas. A study of SRPM’s was undertaken to determine the effectiveness and durability of two types of markers.

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 1994, the department established a large scale Rout and Seal crack seal evaluation program to assess the field performance of eight different sealant products. The products evaluated include the following: Beram 195, Elsro 1191, Bakor 590-13A, Koch 9030, Hydrotech 6160, Crafco 522, Husky 1611, and Super­ Flex 100. Evaluations of the various sealant products commenced in 1994/95 and were finalized in 2002.

Description

Asphalt concrete pavement mix type selection protocols were developed by Alberta Transportation in the late 1980s. Several significant developments in pavements engineering occurred subsequent to the initial development and implementation of these protocols. This report presents the results of a research study carried out to validate the current mix type selection criteria. The results of this study were used by Alberta Transportation to produce a Design Bulletin in July 2003 titled Revisions to Pavement Design Manual for the Selection of ACP Mix Types and Asphalt Binders.

Description

The main purpose of this study was to document the current policies and practices of the three Prairie provinces (Alberta, Saskatchewan and Manitoba) in setting seasonal truck road weight restrictions. Researchers were to also identify opportunities to support a science-based framework for rationalizing and harmonizing the three provinces' regulations and enforcement rules. Key findings from the study were presented in detail in four separate task reports. This executive summary summarizes the results reported in each of the final reports for the project.

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.

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.
