| 摘要： | The report documents a review of Texas Department of Transportation (TxTDOT) design and construction practices with regard to accelerated concrete pavement construction of heavily travelled intersections. Special measures taken by TxDOT at the design and construction level to address the needs presented by overcoming the impact of reconstruction of such pavement facilities were the focus of this review. The review consisted of a field investigation that considered current construction specifications, concrete (fast track) mixture qualification, and construction practices. The field investigation facilitated development of guidelines based on an assessment of the impact present practices may have on performance of the constructed pavements. It was determined the use of fast track paving techniques require coordinated construction planning to take advantage of the benefits offered by this construction process. Concrete mix proportioning can be supplemented by special admixtures to accelerate the time of set, but must also meet the workability requirements associated with the transportation, placement, finishing, and curing of concrete. It is also of benefit to the construction supervisor to qualify the concrete mixture with respect to strength gain for a given set of weather conditions. Laboratory work was conducted to support the development of the mix qualification process. |
