Precast Concrete Boxes Used for Rail AccessCanada and the United States), and load-ings specified by SPH Engineering. The American Railway Engineering and Main-tenance-of-Way Association (AREMA) was formed on October 1, 1997. The Association is a merger of three engineering support as-sociations; the American Railway Bridge and Building Association, the American Railway Engineering Association and the Roadmas-ters and Maintenance of Way Association, along with functions of the Communications and Signal Division of the Association of American Railroads. The mission of AREMA is the development and advancement of both technical and practical knowledge and recommended practices pertaining to the design, construction and maintenance of railway infrastructure. Because the culvert is a shallow bury, the dry cast units were de-
signed to Cooper E-100 Railway Load with four layers of reinforcing steel in each unit instead of the usual two layers.
The culvert was 61 metres long, consisting of 50 units of 3000 mm x 2100 mm boxes. A 210–ton crane with a Cat 953 track loader was used to offload and guide each unit into place. All boxes arrived on site with pre-in-stalled gaskets on the spigot end. The joints were wrapped with a geotextile cloth, when placed into position, to enhance the perfor-mance of the joints and restrict migration of fines into the culvert.
The general contractor for the construction of the new freight and distribution centre was MCI Design-Build Corporation of Lon-don, Ontario. The centre is scheduled for completion in August 2008.

Precast Concrete Box Culvert Designed for Coldwater Fishery & Access To Hydroelectric Dam
By Bob TurnourMunro Concrete [email protected] A twin precast concrete culvert was in-stalled on Highway 634 in Northeastern Ontario to accommodate the biological needs of the coldwater fishery of Brown-rigg Creek and the load of a deep-bury in-stallation. An existing twin 3000mm diam-eter corrugated steel culvert had reached the end of its service life, and the upper part of one of its conduits had deformed. The culvert was no longer structurally functional and had to be replaced.
Highway 634 is a long and isolated bush highway that connects the Abitibi Canyon hydroelectric dam on the Abitibi River at the community of Fraserdale with the rest of the province. It also serves the small community of Smooth Rock Falls at its southern termi-nus where it connects to Highway 11. The 80-kilometer highway is a vital north-south link for northern communities and access road to a major hydroelectric plant owned by Ontario Power Generation.
Replacement of the culvert with a precast concrete structure was specified because of the proven service life (durability) of pre-cast concrete boxes, low maintenance of the culvert over the design life of the proj-ect, and the ease of installation of the units. Early purchase of the concrete box units from Munro Concrete Products in Utopia, near Barrie, provided the Ministry of Trans-portation with additional time to complete any remaining engineering work associ-ated with the tender for the road works. Precast concrete culverts have a lower life
cycle cost compared to other culvert ma-terials, due to longer service life and lower maintenance costs.
The culvert was installed one cell at a time to maintain single lane traffic on the roadway. Being a twin culvert configuration, the wa-ter flow was maintained through one of the existing steel conduits while the new pre-cast cell was installed. The water was then diverted through the first precast cell while the second corrugated steel pipeline was removed and replaced by the second pre-cast cell. A small weir installed at the inlet of one of the 3000mm x 2400mm cells allows a high water level during seasonal periods of low flow to provide for the passage of trout and other wildlife. The 36 units required for the twin-cell structure were shipped to the site, two units per load. The contractor was able to offload the units and place them di-rectly into the trench for installation.
In-water work associated with installation of the culvert could not take place between September 1 and June 15 of the following year, because of construction restrictions

Gasket Material Selection for Concrete Pipe and Structures
By Duncan Spence – Hamilton KentWhatever your application, there are suit-able rubber compounds to meet all gas-ket requirements. This article lists some guidelines for rubber selection based on specific applications, however we strong-ly recommend that you also consult our chemist if chemical concentrations and service temperatures are not clearly de-fined by your customer. Other factors to take into consideration are availability and cost depending on which type of rubber you specify.
The most common rubber used for stan-dard storm and sanitary sewer pipe applica-tions is Polyisoprene (IR) Synthetic Natural Rubber. This is the most cost effective op-tion for gasket material, as IR has all the same performance characteristics of Natu-ral Rubber; i.e. high tensile strength, good compression set resistance and very good tear and abrasion resistance, but at a more competitive price. IR gaskets can also be used in applications where Glycol (de-ic-ing fluid) is being used. In the majority of cases, these gaskets are readily available. Also available for these applications are Styrene-butadiene Rubber (SBR) and an IR/SBR blend.
For box culverts or any applications where the gaskets may be directly exposed to the sun, the rubber offering the best ozone, weather and UV resistance is EPDM (Eth-ylene Propylene Diene Monomer). Another application where EPDM gaskets should be considered is for pipelines running near pulp and paper, or chemical plants, where there can be elevated levels of alkali and acids. Expect to wait from two to four weeks for an order of EPDM gaskets.
Applications involving oil and grease sepa-rators should use either Chloroprene (CR) a.k.a. Neoprene, or Nitrile (NBR) a.k.a. Buna-N. Neoprene will offer good ozone resistance as well as moderate resistance to oils, hydraulic fluids and petroleum-based chemicals. It is also rated good if flame resistance is a concern. The nitrile compound has good ratings wherever oils, hydraulic fluids and petroleum based chemicals are concerned.
It is very important to keep in mind that whether you order neoprene or nitrile gas-kets, delivery is usually in the four to six week range. The reason for this is ex-plained below:
As unprocessed neoprene or nitrile com-pound has a shelf life of approx. 1-2 weeks depending on the time of year. It must be ordered on a project-by-project ba-sis. Lead-time for the compound is three weeks. Once the material arrives, it needs to acclimatize to the ambient temperature of the manufacturing plant for three days. A homogeneous temperature throughout the compound is imperative, before extru-sion, in order to help achieve rubber strip with good dimensional consistency and even density throughout the product. After the extrusion process, the strip needs to sit for an additional two days to allow for latent curing (cooking of the rubber). At this point the strip has reached its desired durometer (hardness) and is ready to be spliced. The newly spliced gasket must sit for 24 hours in order to achieve full splice strength and then undergo a 100% splice stretch test, in accordance with Industry testing param-eters for all oil resistant gaskets. Should any order be placed in the busy summer months for either nitrile or neoprene gaskets it could quite easily run into a six week delivery as a full slate of production schedules must also be factored into the delivery date.
Neoprene and nitrile gaskets cost much more than the regular versions. More ex-pensive, heavier and more difficult-to-pro-cess compounds, extra mandatory testing and more scrap generated in the re-work and repair of these splice–sensitive com-pounds are among the major contributors to the increased cost.
Further considerations need to be taken into account at the jobsite as well. Because each NBR or CR gasket goes through the 100% stretch test, coupled with the fact that the splice strength to begin with is less than with a standard gasket, in-field splice failures may occur from time to time. It is therefore prudent to order 10%-15% more gaskets per pipe size to be prepared should extra gaskets be required. Hamilton Kent will repair or replace, at our discretion, any gaskets that fail in this manner. However we will not accept any responsibility for project delays or consequential damages.

placed on the creek associated with the bi-ology of the fishery. The tender closed on July 3, 2007, with the contractor mobilizing on site by July 19. Poor soil conditions led to complications and delays in construct-ing the detour. Consequently, an exten-sion was required for in-stream operations, which were completed on September 4. Restoration of the roadway, removal of the detour, final trimming and installation of all silt mitigation measures were completed on November 9, 2007.
Although standard sized, the boxes were specially designed to the Canadian High-way Bridge Design Code to accommodate additional reinforcement and meet the engi-neering design of the structure to carry the
heavy loads of the road and traffic. Once installed, the culvert had to perform for at least the design life of the road with low maintenance, because the highway must be open year-round for emergency and ser-vice vehicles, and local traffic.
