Roughton has extensive experience in the overall design of pavements, for both rehabilitation and reconstruction.
We work in tropical and sub-tropical countries with climates ranging from very wet and humid, to desert conditions, and from flood plains to highlands with frost penetration problems.
In order to design remedial measures it is first necessary to test the existing pavement definitively. Pavements are tested for three reasons:
There are two types of pavement performance indicators that provide information about the condition of a pavement structure - functional and structural indicators.
