Otta Seal Construction for Asphalt Pavement Resurfacing

Publication: International Conference on Transportation and Development 2018: Airfield and Highway Pavements

ABSTRACT

Otta seal resurfacing methods have been widely demonstrated for unpaved roads and road rehabilitation in a few states in the U.S. as well as in Scandinavia and Africa. Application of Otta seal over a deteriorated hot mix asphalt (HMA) surface has been considered as the feasible concept that has not been applied for real construction. In this study, a double-layer Otta seal construction over HMA surface was monitored. The applied materials for the construction were introduced. The following performance of the constructed Otta seal layers was evaluated by measuring the international roughness index (IRI) and dust. The road IRI did not significantly change, and the dustometer test results indicated satisfied dust control on Otta seal layer. The findings from this study provide guidance on designing and implementing Otta seal on asphalt concrete pavement as a resurfacing overlay.
