Review of Best Practices in Design, Construction and Performance of Roller-Compacted Concrete Pavement

Description:

Many Roller-Compacted Concrete (RCC) pavements have been installed across North America during the last 40 years, despite limited efforts to develop best practices in design and construction. The origin of RCC pavement can be traced, in some form, as far back as the 1930’s in Sweden. However, the Canadian logging industry spurred RCC pavement’s sustained interest, in the early 1970’s, as a means of moving their water-based log sorting process to land for environmental reasons.

RCC pavement had grown modestly in the 1980’s and 1990’s, due to military and private industrial interest. In recent decades, RCC pavement has been embraced by an increasing number of public transportation agencies in the United States and Canada along with continued private industrial sector growth because of its history of low-cost, rapid construction and early opening to traffic, satisfactory early and ultimate strengths, and durable performance. However, the collection and culmination of data lags this growth.

Significant targeted research, case studies, and performance information has been documented over the decades. Most recently, Louisiana Transportation Research Center (1) has used their Accelerated Pavement Testing facility to evaluate the pavement fatigue life, cracking pattern and failure mode of thin RCC-surfaced pavements, which led to the development of a set of RCC fatigue models for thin RCC fatigue damage analysis.

Additionally, reference tools have been developed, such as the Guide for Roller-Compacted Concrete Pavements from the National Concrete Pavement Technology Center (CP Tech) (2), the Guide to Roller Compacted Concrete Pavements by the American Concrete Institute (3) and FHWA Tech Brief on Roller-Compacted Concrete Pavement (4).

The most viable of this information, if culminated into a volume, would offer a most thorough view of RCC pavement practices and pitfalls for designers and constructors. Equally important, it would also allow for a clearer focus on the most critical future research needs.

Objective:

The objective of this work is to aggregate current state-of-the-practice and known performance of existing RCC pavements.

Benefits:

The most viable of this information, if culminated into a volume, would offer a most thorough view of RCC pavement practices and pitfalls for designers and constructors. Equally important, it would also allow for a clearer focus on the most critical future research needs.

Tasks:

·

Identify and define construction procedures, curing methods, and environmental conditions that influence uniform, and repeatable performing RCC pavements.

·

Identify efficient, cost-effective and reliable mixture design procedures, laboratory and field testing procedures (or gaps in procedures) that would most greatly influence constructability, surface characteristics and durability of RCC pavements.

·

Evaluate the RCC pavement structural design procedures and their performance history including but not limited to load transfer across the joint or crack and durability. Identify the gap in knowledge, if any, for incorporating RCC into current pavement design methods.

·

Define the critical parameters impacting the time at which an RCC pavement could be returned to traffic.

·

Gather information on the performance of existing RCC pavements and most critical factors influencing the performance.
