Demonstration and Purchase of PG Binder Testing Equipment |
摘要: |
To help expedite the implementation of the Superpave methods in the mid-1990's, the Federal Highway Administration (FHWA) conducted a Pooled Fund project that allowed state transportation agencies to purchase shares in this Pooled Fund. Each share provided the state transportation agency with one full set of Superpave test equipment - both for the asphalt binder and the hot mix asphalt (HMA). The pooling of funds gave the states greater purchasing power that resulted lower costs as compared to states purchasing the equipment individually. The majority of the equipment that was purchased under the Pooled Fund was for testing of asphalt binder in accordance with the Performance Grading (PG) system. The binder testing equipment is highly sophisticated and contains sensitive electronics for making the necessary measurements. As most of this equipment has been in service for approximately 15 years, it is nearing the end of its service life and manufacturers are no longer carrying repair parts. With the advent of new test methods such as the Multiple Stress Creep Recovery Test, older direct-shear (DSR) equipment is either not able to run these tests or the results are suspect because of the limitations of the older equipment. States must replace this equipment in order to adopt these new and improved test methods. The objective of this project is to conduct a Pooled Fund project similar to the one conducted earlier by the Federal Highway Administration (FHWA), here in the northeastern part of the country. In Phase 1, researchers will arrange for participating state departments of transportation (DOTs) a demonstration of lab equipment options for performance grade (PG) binder testing. Then in a second phase, CAP Lab will facilitate a pooled-fund purchase of asphalt-binder laboratory test equipment for interested states DOTs. |
