PACA Announces Featured Topics at Upcoming Regional Technical Community Meetings |
|
New tests for SRL rating of aggregate, a demonstration an affordable way to monitor test cylinders and using Portland- Limestone cement will be among the topics featured at the PACA Regional Technical Community Meetings.
Work towards implementation of new test methods for the rating the skid resistance level (SRL) of aggregates is underway. The SRL subcommittee of the PACA - PennDOT Aggregate Quality Improvement Committee is the group established to begin to look at revisions to a system that has been in place since the 1970’s. Members of this subcommittee will report on, and discuss, the work to date as PennDOT moves towards the use of the Three Wheel Polisher and Dynamic Friction Meter to establish the SRL rating of aggregates.
There are now affordable devices that will automatically report the initial curing conditions of test cylinders in the field. We will have a live demonstration of one of these easy to use systems and the free app to automatically record and report what happened to the test cylinders.
Portland Limestone cement (PLC or Type 1L) is now approved for use and available throughout Pennsylvania. Members of our Cementitious Materials Technical Community will present information on the use of and advantages of this product.
Regional PennDOT DME’s, QA personnel, and LTS personnel will once again be invited to join us at each of these meetings.
