The Studies On Joint Materials Of Cement Concrete Pavement In Frigid Area

After investigation and analysis of commonly used joint filler in Heilongjiang Province and perfomance and price comparison of commonly used joint filler,the paper analyses the shortcoming of the present joint filler,discusses selection standards and use requirements of joint filler in frigid area started from joint damage reason,tests and screens for joint filler commonly used in the present cement concrete pavement. Through indoor experimental screening and on-the-spot use performance test,we recommend joint filler of cement concrete pavement fit for Heilongjiang Province,in the meantime,it induces and summarizes pour technique and points for attention of joint filler in construction and it provides a reliable foundation for cement concrete pavement selection and joint filler use of frigid area.
