Stereo photography as a tool in understanding sprayed seal distress mechanisms

In an increasing number of cases, old existing sprayed seals are very stable under traffic. However, when a reseal is needed because of either loss of skid resistance, growth of fatigue cracking, or environmental cracking aided by the brittleness of an aged binder, the fresh reseal is too tender to withstand the current traffic loadings. How can we help reseals survive their first week under heavy traffic? What causes seals to strip? What causes seals to bleed? How can we help seals survive their first cold/wet snap? What are the factors in the development of a strong aggregate mosaic surface in sprayed seals? If we can understand the mechanisms that cause this to happen, we may be able to better control these factors and manipulate them. But first we need a tool that is able to measure the factors involved, so that they can be studied. We may then be able to change each variable one by one, in order to learn which variables are most worth manipulating or controlling. This paper explores the possibility of stereo photography as a tool to understanding sprayed seal distress mechanisms. (a) For the covering record of the conference, please refer to ITRD no.
