In order to study the pavement performance of polyphosphate (PPA) and liquid styrene butadiene rubber (LSBR) composite modified asphalt and mixture, LSBR with 2.0% content and PPA with 0.3%, 0.6%, 0.9%, 1.2% and 1.5% content are selected for compounding. Penetration, softening point, ductility, rotational viscosity and four component tests are adopted to analyze the basic performance, temperature sensing performance and component changes of the modified asphalt. The road performance changes of the composite modified mixture were studied by rutting test, low temperature trabecular bending test, immersion Marshall test and freeze-thaw cycle test. The results show that PPA can effectively improve the temperature sensitivity and high temperature performance of LSBR modified asphalt; With the increase of PPA content, asphaltene gradually increases and colloid decreases, resulting in the increase of asphalt viscosity; The dynamic stability of PPA/LSBR composite modified asphalt mixture is 77.2% higher than that of LSBR, showing good high temperature performance, Compared with freeze-thaw splitting, the failure strain and freeze-thaw splitting of LSBR are reduced by 6.1% and 2.79% respectively, but it is still 2.0% and 2.3% higher than that of SBS modified asphalt mixture, and its comprehensive performance is the best.
