This paper describes briefly the construction and performance of two high-volume fly ash (HVFA) concrete road pavements in India. In addition to data on the materials and mixture proportions used in these projects, test results are given on compression and flexural strengths together with chloride-ion penetrability of drilled concrete cores. The roads have been in service for more than one year. Based on the performance under a traffic load of more than 500 commercial vehicles per day, it can be concluded that compared to asphalt roads, HVFA concrete is more suitable for the construction of rural, regional, and the national network of roads in India.
