ABSTRACT

In Latinamerica road and street pavements are mainly constructed using asphalt mixes. In recent years many government agencies and private companies became interested in building concrete pavements, due to environmental concerns, increasing weight of trucks and a lower life cost equation. The subsisting problem is that initial cost is higher compared with asphalt alternatives. Among other possible solutions to lower the initial price, Roller Compacted Concrete Pavements CRCCP) seems to be a practical and easy alternative for the region.

In this paper six different pavements are studied: regular concrete, two types of RCC and three different asphalt pavements. The whole life cost of the six alternatives is determined, based on authors' experiences in many countries of Latinamerica.

A field test was conducted to compare the long term performance of a RCC and an asphalt pavement. In the present paper 40 months of continuous monitoring is summarized.
