• Abstract:
  Louisiana experimented with various techniques and treatments to control reflective cracking since the ; 1970s. The objective of this study is to evaluate and compare different reflective cracking control ; treatments by evaluating the performance, constructability, and cost-effectiveness of pavements built ; with these treatments across the state. To achieve this objective, a survey of current state practices ; identified the treatment methods that are used or that had been used to delay and mitigate reflective ; cracking in composite pavements. Based on this survey and a thorough review of LADOTD databases, ; pavement sections built with reflective crack control treatment methods were identified. Projects with ; sufficient years in service and with available untreated segments were selected for detailed ; performance and economic evaluation. In total, the performance of 50 different sites that were ; constructed with various treatments was evaluated for a period ranging from 4 to 18 years. Among ; various treatments that were analyzed, saw and seal, and chip seal as a crack relief interlayer showed ; the most promising results in terms of performance and economic worthiness. The cost effectiveness ; of fiber-glass grid was not validated as compared to regular HMA overlays. Stress absorbing ; membrane interlayer and high strain asphalt crack relief interlayer (STRATA®) showed mixed results ; in terms of performance. In addition, there were an insufficient number of projects for paving fabrics ; to allow for drawing conclusions on the cost-effectiveness of this treatment method.
