Construction of HVFA concrete pavements in India: Four case studies

摘要

The technology of HVFA concrete is being used for pavement construction in India. The puper describes briefly four case studies involving construction of pavements with HVFA concrete. Data are provided on the materials properties and mixture proportions used in these projects. The test results of compressive and flexural strengths of concrete are also presented together with the chloride-ion penetrability test data on cored samples from the pavement. Performance of the HVFA concrete pavements under heavy traffic of up to 500 commercial vehicles/day was monitored for one year and the same was observed to be satisfactory. The author suggests that HVFA concrete is suitable for the construction of national, regional and rural road network in India.
