Abstract:

Microsurfacing is a relatively new technology. As such, there is great interest in assessing its efficacy as a preventive maintenance treatment. This paper investigates the long-term benefits of microsurfacing applications at various highway sections in Indiana. The measures of effectiveness (MOE) used are treatment life, increase in average condition, and area bounded by the treatment performance curve. Each MOE was expressed separately in terms of three performance indicators – surface roughness (IRI), Pavement Condition Rating (PCR), and Rutting (RUT). The results show that for each MOE and performance indicator, the treatment effectiveness is influenced by climate, traffic loading, and highway class. The results also show that the effectiveness of microsurfacing is most perceptible when rutting is used as the performance indicator. When treatment service life is used as the MOE, microsurfacing effectiveness ranges from 2–10 years (on the basis of the IRI performance indicator); at least 15 years (on the basis of rutting); and 4–15 years (on the basis of PCR). When the increase in pavement condition is used as the MOE, the treatment is seen to offer 7–27% and 90–96% reductions in surface roughness and rutting, respectively, and a 2–7% increase in PCR. Finally, when the area enclosed by the microsurfacing performance curve is used as the MOE, it is seen that this treatment offers benefits of 30–258 IRI-years, 15–67 RUT-years, and 18–56 PCR-years (IRI in inches per mile, RUT in inches, and PCR in units on a 0-100 scale). The case study results generally demonstrate that microsurfacing is a promising treatment in addressing rutting and in extending pavement life in general.
