technical brief
low-noise micro-surfaces were constructed using materials such as interfacial interfacial agents and emulsified sbs/sbr composite modified asphalt. it has the characteristics of interlayer adhesion to prevent sheet loss, excellent high and low temperature performance, good wear resistance, and low noise of 2~3db compared with traditional micro-surfacing.
(1) the interfacial agent regenerates the aged asphalt to improve the interlayer adhesion;
(2) emulsified sbs/sbr composite modified asphalt has excellent high and low temperature performance;
