Action identification was primarily informed by an extensive literature review conducted by researchers from FPInnovations along with those from TenCate. The literature review, through consideration of evidence-based academic articles, sought to reinforce understanding of the root causes of edge cracking, considering both how the roadway was constructed as well as how its ultimately utilized. The review found that edge cracking can be partly credited to under-compacted materials along the shoulder or side of the road. This under-compaction can be attributed to a natural tendency for shoulders and slopes to be difficult to compact (due to their steepness, positioning, etc.). This weakness can be exacerbated by the usage of these roads by heavy vehicles. Under-compacted materials can also allow for higher retention of water further compromising the integrity of the edges. Finally, weakening can also be attributed to over-steepened side slopes as well as frost heave and thawing. From a maintenance standpoint, plowing snow into the shoulder can also have an impact on cracking. Spring thaw combined with the mass of snow on the shoulder creates differential thawing which has a major effect on the integrity of the edge. With the multiple causes of cracking clearly established, the project team was primed to utilize novel techniques such as that of geotextiles to attempt to address the persistent problem.
