Variation in Otta Seal application for different scenarios (Manica and Zambezia provinces, Mozambique.

Abstract

In some areas in the southern part of Mozambique deposits of calcrete can be found, which the RRIP (Rural roads investment programme) and the AFCAP project is using for construction of Otta seal surfacing. Otta seal is a low-cost road surface treatment constructed by placing a 5- 30mm graded local natural gravel aggregate on top of a thick application of relatively soft bituminous binding agent.
