Abstract
About 34.2% of unbound Lithuanian granular roads, which need to be sealed, are with low traffic volume. The cost of maintenance, loss
of time, social discomfort and other problems of travelling on gravel roads bring financial failure annually. Usually, problems of this kind
are solving by paving asphalt, but in practice it is very expensive and causes problems of safety road. As the result, the most effective
solution for gravel roads by aspects of cost and performance is Otta seal. This paper aims to illustrate the behaviour of Otta seal at traffic
and climatic conditions of Lithuania. The experimental research has been done for 26 sections of gravel roads, which were surfaced with
the double Otta seal by rehabilitation. There are analysed characteristics of materials and one year’ performance of the double Otta seal in
all objects of investigation and based on the results of this research, there are made conclusions.
Keywords: double Otta seal; soft (low viscosity) bitumen; aggregates; visual assessment; gravel road; low-volume road.
