PHASE II REPORT - Caltrans

surfacing applications (i.e., traffic volume, application thickness, and curing mechanisms), the
similarities of the tests currently used indicate that the two systems must be studied together.
The States that contributed to the pooled fund study are: California, Delaware, Georgia, Illinois,
Kansas, Maine, Michigan, Minnesota, Missouri, New Hampshire, New York, North Dakota,
Texas, and Vermont.
2.2 OBJECTIVES OF THE POOLED FUND STUDY
The overall goal of the pooled fund study is to improve the performance of slurry seal and microsurfacing
systems through the development of a rational mix design procedure, guidelines, and
specifications.
Phase I of the project had two major components; the first consisted of a literature review and a
survey of industry and agencies using slurry and micro-surfacing systems; the second part of
Phase I dealt with the development of a detailed work plan for Phases II and III. The Phase I
effort is complete and all findings were summarized in the Phase I Report.
In Phase II, the project team evaluated existing and potential new test methods, proposed a
rational mix design procedure, conducted ruggedness tests on recommended equipment and
procedures, and prepared the subject report that summarizes all the activities undertaken in
Phase II.
In Phase III, the project team will develop guidelines and specifications, a training program, and
provide expertise and oversight in the construction of pilot projects intended to validate the
recommended design procedures and guidelines.
2.3 PURPOSE OF THE PHASE II REPORT
The purpose of this report is to summarize the findings and recommendations of the Phase II
effort. The report provides the following:
1.0 The development of a preliminary mix design procedure.
2.0 The evaluation of new and improved tests for understanding the short term and long
term properties of slurry systems.
