Hot Mix Asphalt Research Investigation for Connecticut, Part D – Evaluate the Feasibility of Using Permeability for In-place Density Dispute Resolution on Bridge Decks

The presence of water in asphalt pavements is detrimental to the life of the pavement. Most construction specifications require the pavement to be compacted to a specific air void content. As an asphalt pavement’s air void content increases, the permeability of that pavement will typically increase. The relationship between density and permeability indicates that the lower the density the higher the permeability. Pavement permeability can cause significant issues on bridge decks. For example, if steel reinforcing is exposed to water and salt permeating through the pavement, oxidation can occur and steel members will begin to deteriorate rapidly. Therefore, the objective of Part D of the Connecticut (CT) hot mix asphalt (HMA) study is to determine if measuring the permeability of a pavement on a bridge deck will work as a non-destructive dispute resolution test for the in-place density of the pavement. The data collected and analyzed for this research indicates there is an exponential growth in permeability as the percent air voids increase. However, for a permeability based dispute resolution process to be implemented the field testing method would need to be much more sophisticated than current methods. The subjective nature of the test has the potential to cause more disputes than it would resolve.
