Abstract EN
Gravel roads play an important role in the transport infrastructure.
However, their maintenance (especially the control of dustiness using chemical dust suppressants) is expensive.
Besides, the condition of gravel roads results in low driving comfort, longer travelling time, faster vehicle amortization, and so forth.
Typically, these problems are solved by paving gravel roads with asphalt wearing layer.
However, north countries practice had shown pavement structure high susceptibility to frost due to insufficient thickness of frost resistance layer.
The construction of thicker frost resistant layer increases road construction cost by 25% and, in most cases, there is no need to increase bearing capacity by increasing total thickness of pavement structure.
In 2012 19 gravel roads were constructed using cost effective rehabilitation technologies—soft asphalt and double Otta Seal in Lithuania.
This paper focuses on those two technologies’ performance within first three years of constructed roads exploitation.
The implemented experimental research consisted of three parts by evaluating constructed roads base layers bearing capacity; pavement roughness; and pavement distresses and defects.
As a result, the acceptable performance indicators were determined for both technologies—soft asphalt and double Otta Seal.
Also recommendations for construction and exploitation improvement were defined.
