Project Summary

Hoyle Tanner was retained by the City of Danbury to provide professional engineering services to reconstruct and mark a portion of the parallel taxiway to Runway 8-26, and to reconstruct a portion of the parallel taxiway to Runway 17-35.

Block cracking had become evident over the majority of the taxiway pavement. This type of cracking is normally seen in old pavement surfaces. Alligator cracking was also noted, indicating that the aggregate base course had become contaminated with fine soil particles, which forces water to rise into the pavement in a capillary action. Many of these cracks were beginning to develop the potential for “pothole” situations with loose and broken pavement which could result in damage to aircraft. Rather than do full depth reconstruction over the entire length, Hoyle Tanner in consultation with the owner chose to remove only the poorest areas of pavement based on subsurface soils investigations. The remainder was a “reconstituted” base by blending some of the existing base material with the existing bituminous material that had been crushed. The surface was then paved with Hot Mix Asphalt (HMA).
