Abstract

The Amazon region is characterized by unusual situations such as low support capacity or scarcity of coarse aggregates that motivate the interest to develop specific paving solutions. In addition, the intense rain regime, seasonal floods and technological isolation reduce the period of work for carrying out the works. Thus, work procedures for fast execution pavement are proposed, which consists of a single layer of semi-rigid base using the subgrade soil stabilized with cement and chemical additive based on synthetic zeolite. Procedures are evaluated through a case study located on a military road, adjacent to AM-010. Pavement dimensioning, execution and technical evaluation by visual inspection and resistance tests were developed. It can be concluded that the soil-cement-additive base pavement appears as an alternative in regions with geomaterial scarcity, limited execution time and risk of flooding.
