Abstract
Longitudinal edge cracking has caused asphalt pavement failure in Colorado for many years. The purpose of this research was to determine the probable cause or causes of edge cracking in asphalt pavements in residential subdivisions. Eight locations at three sites in Colorado were sampled. A fourth site was identified, and soil samples were collected before construction in an attempt to obtain precracking soils data. The three primary findings of the study were 1). The edge cracking observed at all eight locations in this study began at the top of the pavement. This means that upward movement from below and/or bending is causing excessive tensile strain at the surface of the pavement. 2) Lower density and higher moisture than optimum of the subgrade beneath the edge cracks appears to be related to the cracking. 3) The soils at all locations were plastic clays with potential for high volume change. It seems likely that swelling of these soils contributed to the edge cracking; however, no strong correlation was found.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
