The Application of Semi-Flexible Pavement on Heavy Traffic Roads

Semi-flexible pavement mixture and AC-16 asphalt concrete performance is this paper's focus. Aggregates meeting the lower limit, middle value, and upper limit of the mother mixture gradation curves were used to prepare semi-flexible mixtures. The low temperature performance of both mixtures was investigated through the indirect tensile test and the low temperature bending test. There was determination of brittle point temperatures and strain energy density indices. Study results showed that, in comparison with AC-16 styrene-butadiene-styrene (SBS) modified asphalt concrete, semi-flexible pavement mixture has excellent low temperature crack resistance. Also, crumb rubber modified semi-flexible pavement water stability, low temperature crack resistance, and high temperature stability were studied in the laboratory, and there was comparison with AR-AC-16 asphalt concrete with asphalt rubber. Finally, there was construction of test pavement. That semi-flexible pavements with asphalt rubber give excellent performance was shown in both laboratory tests and the test pavement. Good application prospects are enjoyed by such pavements, especially for service as a surface course on pavements with heavy traffic.
