摘要: |
Current maintenance techniques for the repair of D-cracked concrete pavements are costly and not very effective. In an effort to solve this problem two relatively new materials were used on a section of I-90 in southwestern Minnesota. Silanes were used in an attempt to retard the D-cracking process by protecting the pavement from moisture and chemical damage. The other material, High Molecular Weight (HMW) methacrylate monomers, generally acts as a "glue" to cement the fractured concrete particles back together. Both materials were placed on three separate test sections. Four silanes and three HMW methacrylates were used. Each test section varied in the extent of D-cracking present. Results to date indicate that the effectiveness of silanes in extending the service life of D-cracked concrete pavements is questionable. They appeared to reduce cracking in one test section but performed similar, or worse, than the control in the other two. HMW methacrylates appear to be effective in holding a D-cracked pavement together for approximately 18 months. However, the pavement must have cracks wide enough for the material to penetrate and form a substantial bond. |
