Study on bonding properties of porous asphalt mixture under different conditions
High viscosity modifier A is used to modify SBS modified asphalt,and the bonding properties of porous asphalt mixture under different conditions are studied by Cantabro test.The results show that increasing the number of freeze-thaw cycles,maximum nominal particle size and water content can increase the scattering loss of porous asphalt mixture,but fibers can effectively decrease the loss.When the number of freeze-thaw cycles is 1 or 8,the loss of PAC-16 is 17.60%and 3.90%higher than that of PAC-13,the loss of PAC-13 containing fiber is 15.34%and 17.94%lower than that of PAC-13 without fiber,and the loss of specimen under water condition is 18.58%and 36.63%higher that of specimen without water,respectively.
