| 摘要： | This report summarizes the condition assessment of the pavement structure on I-65 between mileposts 97.5 to 102.5. Three types of equipment were used to evaluate the present condition of the pavement; falling weight deflector meter, ground penetrating radar, and coring machine. Results indicate that durability of the existing concrete surface appears to be the most detrimental problem encountered in this survey. Load-transfer across transverse joints appears to be in acceptable ranges. Limited areas were identified to have less than four inches D.G.A. beneath the concrete pavement. These areas have also been experiencing the most differential settlement. In addition several areas are experiencing water trapped beneath the concrete surface due to inadequate pavement drainage. |
