Perspectives on Portland-Limestone Cement
- Wednesday, 13 May 2020 12:14
ACPA’ has published a “Perspectives” document stating the Association’s support for and encouragement for the acceptance and use of portland-limestone cement (PLC) or Type IL cement.
ACPA supports and encourages state DOTs and other agencies to allow its use as an option to help further improve concrete’s sustainable attributes.
PLC is an innovative cement that contains between 5% and 15% finely ground limestone, which can help reduce the carbon footprint of cement production by about 10% relative to ordinary portland cement (OPC).

ACPA Perspectives documents detail the Association’s formal positions and policies on timely issues of importance to the concrete pavement industry and the transportation-construction community. This is the 2nd new addition to the library this year.
Perspectives on Recycled Concrete Aggregates

ACPA has released a new two-page document covering recycled concrete aggregates (RCA) and their use within new pavement structures. The document is part of the Association’s ‘Perspectives’ series, which inform the concrete pavement community about policies, practices and positions on key topics.
Eric Ferrebee developed the document to provide insights into what is now a standard and essential practice by the concrete pavement industry because of RCA’s numerous sustainability (economic, environmental and societal) benefits.
The two-page document explains RCA has been used successfully, is supported by the FHWA, and is specified in paving concrete pavement applications in over 40 states across the country.
The document also conveys both the primary application (for base/subbase layers), as well as secondary applications. Click here to download a copy of the document, which is included in ACPA’s ‘Perspectives’ library.
