A platform for research: civil engineering, architecture and urbanism
This research study evaluated the performance of various pavement preservation treatments over time and under different environmental conditions to quantify the economics of each treatment type. There are three primary techniques utilized in Colorado for preservation of asphalt pavements and three for concrete pavements. For asphalt pavements these are crack sealing, chip seals, and thin hot mix asphalt overlays. For concrete pavements the treatments are joint resealing, cross-stitching, and microgrinding. Full-scale test sections were constructed in 2005 and some additional test sections previously constructed were also included for performance measurement. These test sections include crack sealing, chip seals, thin overlays, joint resealing, cross-stitching and microgrinding. Test results indicate that continuation of crack sealing, chip sealing, and thin hot mix overlays is justified for asphalt pavements. Performance results of the preservation treatments for concrete pavements were not as successful. Propagation of the crack into the adjacent slab occurred in the cross-stitching test sections. Microgrinding concrete pavements does not appear to be effective at reducing cracking and may be detrimental to performance. The disappointing results of the joint resealing test sections indicate that a review of the specifications should be considered.
