Construction Projects


The Township of Cavan Monaghan completes their Capital Road Projects from May-September.  The three main Capital Programs for Roads are Slurry Seal, Surface Treatment and Hot-Mix Asphalt. 

Capital Work for 2024

 Surface Treatment

Surface Treatment is the application of an asphalt emulsion on either an existing asphalt road or a fresh, compacted granular surface immediately followed by the application of a cover aggregate. It provides an economical all- weather surface for light to higher volume traffic depending on the emulsion and quality of aggregate used. It also provides a waterproof barrier that prevents the intrusion of moisture into the underlying materials and provide a skid resistant surface.

 Slurry Seal

The Township's current process is to complete Slurry Seal on a road the year following Surface Treatment. Slurry seal is a mixture of well-graded fine aggregate, mineral filler, asphalt emulsion and water applied to a pavement as a surface treatment. It protects the existing surface from moisture intrusion, fills surface voids, cracks and minor depressions in the pavement, retards further oxidization of the existing pavement, provides a skid resistant surface and extends the service life of the existing pavement.

 Hot-Mix Asphalt

Hot mix asphalt (HMA) consists of a combination of aggregate uniformly mixed and coated with asphalt cement. To dry the aggregates and to obtain sufficient fluidity of asphalt cement for proper mixing and workability, both the aggregate and asphalt must be heated prior to mixing hence the term hot-mix. Aggregates and asphalt are combined in a mixing facility in which all of the constituent materials are heated, proportioned and mixed to produce the desired paving mixture. After plant mixing is complete, the hot mix is transported to the paving site and spread with a paving machine in a loosely compacted layer to a uniform, even surface. While the paving mixture is still hot, the material is further compacted by heavy motor-driven rollers to produce a smooth, well-consolidated pavement layer.

The Township of Cavan Monaghan attempts to minimize roadway disruptions. The Township apologizes for any inconvenience that these projects may cause and appreciates your cooperation throughout the construction process..
