Chen, S and Jiang, Y (2008) Pavement reflective cracking control with coarse-aggregate asphalt mix interlayer. International Journal of Construction Education and Research, 4(3), pp. 200-209. ISSN 1557-8771
Abstract
A test road was constructed using different asphalt concrete overlay treatments. The field observations conducted after 3 years of the pavement being in service indicated that the coarse-aggregate asphalt mix interlayer worked exceptionally well in reflective crack control. A three-dimensional finite element analysis showed that the main stresses in the coarse-aggregate asphalt mix interlayer were lower than those in the normal asphalt concrete interlayer with the same thickness. It is believed that the large-size aggregates and high air voids in the mixture can block the paths of initial cracks to extend to the top of the interlayer.

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
