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

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

Paint is the most common material used for transverse pavement markings (crosswalks, stop bars, traffic arrows, etc.), as it is relatively inexpensive, easy to apply and dries quickly after application. However, it requires periodic remarking due to the deterioration caused by traffic, snow removal equipment and environmental forces. A project was conducted to determine the effectiveness of two types of alternative pavement marking materials (System 400 & PolyCarb Mark-55.4) to find more durable pavement marking materials.

Study to evaluate the performance of fluorescent retroreflective sheeting (yellow green) for chevrons

Description

Several vehicle rollovers occurred during the first 48 months of service of the Highway 2/3 interchange near Fort Macleod. Fluorescent yellow green (FYG) retroreflective sheeting product was... More ≫

Description

Several vehicle rollovers occurred during the first 48 months of service of the Highway 2/3 interchange near Fort Macleod. Fluorescent yellow green (FYG) retroreflective sheeting product was subsequently installed at the interchange, and this study evaluates the effectiveness of this in reducing vehicle speeds when approaching this curve. The use of these chevron signs at this location help improve motorist maneuvering through this curve. Similar FYG signage should be considered for locations where early detection is required to heighten the travelling public's awareness of an unfamiliar or non-typical condition.

Description

Road signage using Durable Fluorescent Diamond Grade Sheeting (DFDG) was installed in 1997 in the Peace Region, North Central Region and Southern Region to evaluate the effectiveness of DFDG signs in improving work zone safety on Alberta highways. Results of the study showed that DFDG signs are highly visible, easy to read and help improve work zone safety, and the report recommends that DFDG signs be used on all construction projects to improve work zone safety.
