The field surveys of the test sections indicated that the two-year period is not long enough to assess differences in field performance of the various anti-strip additives. The following extended performance monitoring program is recommended:
Conditions surveys of the test sections should be continued on an annual basis (annually using Research staff and biennially by the researcher).
Field cores should be obtained after 5 and 8 years of service or as seems necessary by the condition surveys.
Field cores should be evaluated through a laboratory program similar to the one used on the two years old cores.
This research project is intended to provide further monitoring and field verification of performance differences between the various test sections.
