Abstract: The application of PLS concrete in rural highway can not only greatly reduce the engineering cost and solve the fund problem of rural highway construction, but also solve the problem of fly ash - acetylene sludge disposal. At the same time, it is advantageous to environmental protection. Combined with the test road, the mixture ratio design, key road performance and construction technique of PLS concrete are studied, which can be taken as a reference for valuable experience to the wide application of PLS concrete on rural highway in our country.
