Description

Template Technical Field The present disclosure relates to a template. In particular, the present disclosure relates to a template having a plurality of cells defined by walls of the template. Background The pavement can be constructed as a flexible pavement or a rigid pavement. Each type of construction has particular advantages and disadvantages. A pavement as described herein includes any suitable structure, material, and/or substance positioned over an area intended to sustain vehicular or pedestrian traffic. For example, roadways include, but are not limited to, sidewalks, bike ways, roads, track beds, parking lots, and aircraft runways. The flexible pavement includes an underlayment laid on a subgrade or existing natural material, a base course laid atop the underlayment, and an asphalt surface layer laid on the base course. The surface layer includes one or more layers of asphalt or hot mix asphalt concrete (HMA). The structural characteristics of the flexible pavement are determined by the combination of the different layers and the surface layer itself has negligible structural integrity due to the load distribution into the underlying layer. Although the materials required for construction of flexible pavement are relatively inexpensive by volume, the nature of construction means that the depth and volume of material required is significant, especially in roads required to support high loads, where roads require more than one meter of additional material to be provided atop the subgrade. Therefore, the construction cost of flexible pavements (particularly pavements subjected to high loads) is significant. Likewise, transporting a desired volume of material to a remote location can be problematic in terms of logistical requirements. Damage to flexible pavement is also common because the surface layer does not have significant structural integrity and can cause voids from impacts, such as those caused by traffic loads forcing rocks into the surface. As the vehicle passes over the surface layer of the flexible road surface, the friction created by the tires causes it to expand. Over time, this may lead to surface cracking, allowing water to gradually attack the surface layer from below and/or inside, leading to the formation of larger cracks and potholes. In the event of cavities or voids in the substrate or footbed, which may be caused by potholes or other imperfections, repair of the flexible pavement is difficult and expensive, as the entire pavement must be excavated and re-laid. The flexible pavement is also subjected to extreme temperatures which can cause the surface to become tacky. This may lead to further degradation of the flexible pavement. Rigid pavement, on the other hand, comprises a surface layer, typically in the form of a concrete slab, cast over a base layer, optionally including a foundation laid on the subgrade. The stiffness provided by the concrete slab allows for a more even load distribution, potentially allowing for fewer or shallower underlayers. Concrete is adversely affected by temperature variations and expansion-related cracking can be mitigated by having several separate plates, with adjacent plates tied together, for example, with rebar pins or ties. Concrete is also relatively expensive by volume and, although construction of a rigid pavement requires less depth than a flexible pavement, construction costs are greater by area. In addition, the logistical problem of providing concrete to remote locations is significant, and therefore, rigid pavement is not a viable option at all for many remote applications. Due to the high loads, concrete cracking is common, especially toward the edges of the slab where the support substrate may move more easily. The repair of concrete slabs is also more difficult than flexible pavement because it is necessary to cut the cracked concrete slab and pour new concrete into place, rather than simply filling the small holes with asphalt or HMA product. In addition, in the event of cavities or subsidence in the substrate or footbed, repair of the rigid pavement is difficult and expensive because the entire pavement must be excavated and re-laid. The installation of a rigid pavement may generate significant CO 2 and other greenhouse gas emissions, and the total emissions during construction may be 5 to 6 times higher than that of a flexible pavement, mainly due to the effect of the concrete volume. Thus, known pavement construction methods are expensive, require large material volumes and involve considerable CO 2 emissions and other greenhouse gas emissions. Further, existing roadways, whether flexible or rigid, are difficult to repair when damaged.
