Implementing AASHTO TP 110 for Alkali-Silica Reaction Potential Evaluation of Idaho Aggregates
| 项目名称： | Implementing AASHTO TP 110 for Alkali-Silica Reaction Potential Evaluation of Idaho Aggregates |
| 摘要： | AASHTO T303 and/or ASTM C1260 were previously developed to evaluate the susceptibility of aggregates to Alkali-Silica Reactivity (ASR). These tests have shown conflicting results depending on the length and type of the test even on the same aggregate source. A new test procedure, AASHTO TP 110, was recently developed to overcome the shortcomings of the current tests. This method has been found to provide good correlations with ASTM C1293 results, as well as field performance. The main objective of this study is to evaluate the advantages associated with implementing AASHTO TP-110 within ITD specifications to quantify the ASR potential of aggregate sources in Idaho. The baseline ASR susceptibility for Idaho aggregates will be established. ASR potentials quantified through the AASHTO TP-110 procedure will be evaluated in light of ASTM C1293 and ASTM C 1260 (AASHTO T 303) test results. |
