摘要: |
Condition surveys of continuously reinforced concrete pavements in Texas have revealed that significant performance differences exist among pavements constructed with different coarse aggregates. To reflect the difference in performance, a new design standard has been developed, one based on the material properties of concrete containing the two types of coarse aggregates most often used in Texas-siliceous river gravel (SRG) and limestone (LS). To determine whether the performance of pavements in the field is in accordance with that predicted by the computer program, test sections were constructed and monitored for approximately 1 month after construction at four locations in Houston, Texas. The test sections were constructed to permit observations of the effects of (1) the coarse aggregate type and (2) the quantity of reinforcing steel used. |
