Alkali Silica Reaction (ASR) Objectives 3 And 4
| 项目名称： | Alkali Silica Reaction (ASR) Objectives 3 And 4 |
| 摘要： | Federal Highway Administration (FHWA) has initiated Alkali-Silica Reactivity (ASR) Development and Deployment Program consistent with the requirements of SAFETEA-LU legislation. The objective of this research is to eliminate/reduce the deteriorating effects of ASR in highway concrete structures even when exposed to adverse natural environment and/or additionally altered by the use of cost effective deicers/chemicals. The results from this research will directly support ongoing efforts to improve the durability of highway infrastructure including pavements, brides, and other concrete highway structures. The proposed ASR research activities have four objectives. Objectives 3 and 4 contract was awarded to Transtec Group. Objective 3: Non-destructive field test methods for evaluation of concrete structures for: presence of ASR; concrete deterioration rate and predict future expansion. Objective 4: Develop cost effective methods to control ASR and extend service life of existing highway structures. |
