THIN MAINTENANCE SURFACES. PHASE ONE REPORT.

The first phase of a two-phase research project was conducted to develop guidelines for Iowa transportation officials on the use of thin maintenance surfaces (TMS) for asphaltic concrete and bituminous roads. Thin maintenance surfaces are seal coats (chip seals), slurry seals, and micro-surfacing. Interim guidelines were developed to provide guidance on which roads are good candidates for TMS, when TMS should be placed, and what type of thin maintenance surface should be selected. The guidelines were developed specifically for Iowa aggregates, weather, traffic conditions, road user expectations, and transportation official expectations. In addition to interim guidelines, this report presents recommendations for phase-two research. It is recommended that test section monitoring continue and that further investigations be conducted regarding thin maintenance surface aggregate, additional test sections, placed, and a design method adopted for seal coats.
