| Summary: | Despite extensive road construction
programs over the last century, a substantial proportion of
roads remained unsealed especially in developing and
emerging economies. As these economies develop, the demand
arises to seal previously unsealed roads. The most
economical transition point between unsealed and sealed
roads depends on many conditions that need to be evaluated.
The purpose of this Note is to provide guidance for decision
makers, engineers and administrators on selecting the most
appropriate surface for unsealed road given the prevailing
conditions. It is based on the report "Surfacing
Alternatives for Unsealed Roads" (report 37192). |
