Nov. Nooner – Construction of Roadway Fill Over Large Water Body with Geotextiles

Description

Join us for our second Nooner of the 2019-2020 season! Brent Marjerson from WSP will be presenting on the construction of roadway fill over a large water body using geotextiles at Highway 7 near Vanscoy, Saskatchewan.

Our Nooners include the buffet lunch at the Park Town and free parking (just register at the front desk). Lunch starts at 12, with presentation to follow at ~12:30 pm.

Presentation Summary:

A high strength woven geotextile was used in the construction of a roadway embankment over a large water body as part of control section 7-02 on Highway 7. The geotextile design was required to support the embankment loading and traffic loading while at the same time bridging the soft organic saturated material at the bottom of the water body. The embankment was constructed in the winter months on top of the frozen surface of the water body to prevent disturbance of the water body and to allow for ease of construction through decreased environmental concerns. The construction of the embankment during the winter on the ice significantly reduced construction costs and eliminated the potential requirement for a complete re-route of the embankment around the large water body. The embankment was constructed with sufficient fill to ensure that once the ice had melted in the spring and the embankment settled, the final height would be a minimum of 1.0 metres above the high water level of the water body. This would facilitate the completion of the construction of the grade in the spring with select borrow material working on a stable subgrade passing through the entire length of the water body. The design of the geotextile reinforced embankment consisted of the estimation of the settlement of the underlying soil and the determination of the required width of geotextile to ensure that the entire embankment was underlain by the geotextile including approximately 1.0 metres of extra width as a contingency. To ensure that the geotextile support was consistent for the entire width of the embankment the rolls of woven geotextile had to be sewn together at the factory prior to shipping and the size of the roll needed to be such that the material could be moved on site with standard equipment.

CSCE Saskatoon Oct. Nooner – Tack Coat Materials in Cold Climate

Description
Join us for our first Nooner of the 2019-2020 season! Dr. Haithem Soliman from the University of Saskatchewan will be presenting on the performance of tack coat materials in cold climates.

Our Nooners include the buffet lunch at the Park Town and free parking (just register at the front desk). Lunch starts at 12, with presentation to follow at ~12:30 pm.

We greatly appreciate all ticket orders made three days in advance of the Nooner (including for those using corporate sponsor vouchers), so we can let the venue know how many people we expect. Please take advantage of our early bird pricing, which we offer up until 3 days before the event!

Presentation Summary:

Tack coat materials are used to provide sufficient bond between an old asphalt concrete layer and a new asphalt overlay, or between asphalt concrete lifts. Tack coat materials are typically bituminous emulsions. A successful application of a tack coat material depends on the followed construction practices and material properties. For construction practices, a uniform application of the tack coat material and having enough curing time before allowing construction traffic ensure that a sufficient amount of the bituminous residue will stay at the road surface and reduce pickup and tracking by construction equipment. For material properties, a sufficient bond strength of the tack coat material ensures the structural integrity of asphalt concrete layers and prevent premature failure. In cold regions, durability of tack coat materials and resistance to freeze-thaw cycling must be considered too. Specifications for tack coat materials should balance between construction limitations and specifying materials with an acceptable performance.

The presented research aims to assess the performance of several tack coat materials in Saskatchewan climate. A summary of testing results, evaluation methods, and impact of construction conditions will be presented and discussed.

Speaker Biography:

Dr. Haithem Soliman is an Assistant Professor in the Department of Civil, Geological and Environmental Engineering, University of Saskatchewan. He completed his Ph.D. degree at the University of Manitoba in 2015. During his work in Manitoba, Dr. Soliman participated in several projects in various areas including performance-based testing of pavement materials, durability of pavement repair products in cold climates, use of recycled materials in pavement construction, and influence of frost penetration and spring thaw on pavement structures. Currently, Dr. Soliman has ongoing research projects at the University of Saskatchewan, which include characterization of aggregate materials for base and subbase layers, evaluation of tack coat materials, performance of polymer-modified asphalt mixtures, and using imaging techniques to evaluate freeze-thaw durability of asphalt mixtures.

CSCE Saskatoon Mar. Nooner – Yorkton Grain Mill

Description

Join us for our last Nooner of the 2018-2019 season! Mazen El-Mousa, P.Eng., from Lafarge Canada Inc. will be presenting the Yorkton Grain Mill project, which utilized precast concrete for the structural system.

Our Nooners include the buffet lunch at the Park Town and free parking (just register at the front desk). Lunch starts at 12, with presentation to follow at ~12:30 pm.

We greatly appreciate all ticket orders made three days in advance of the Nooner (including for those using corporate sponsor vouchers), so we can let the venue know how many people we expect. Please take advantage of our early bird pricing, which we offer up until 3 days before the event!

Presentation Summary:

This presentation will detail the selection and production of precast concrete for the structural system of the Yorkton Grain Mill facility. The Engineer of Record, WSP Canada Inc., and the Construction Manager, VCM, prepared preliminary designs for the building utilizing three different structural systems: precast concrete, cast-in-place concrete, and structural steel. The main criteria for deciding on a structure were combustibility, speed of construction, and economy. The precast concrete option prevailed. The Engineer of Record and Construction Manager were precast friendly, and precast concrete by Lafarge was selected due to speed of construction, longevity of the structural system, and confidence in Lafarge performance. In particular, this project required winter construction, a tight completion schedule, and particular budgetary restraints, all of which contributed to the selection of precast as the structural system.

Speaker Biography:

On June 28th, 1976 in the City of Kuwait, on summer day reaching 52 degrees Celsius, history broke and Mazen El-Mousa was born to a Kuwaiti mother and Jordanian Father.
