- Abstract:
- For the researeh of the technology performanee of PEG modified asphalt, the brookfield viseosity.penetration, softening point and duetility was determined, and the performanee of the PEG modified asphalwas analyzed. Through the determination of residual penetration ratio and residual ductility, the aging perform-anee of PEG modilfied asphalt was analyzed ; through the viseosity-shear rate curve, the rheologieal properly olasphalt was analyzed; the construetion temperalure of PEG modified asphalt mixture was obtained through theviseosity-temperature curve and it was analyzed. The results show that with the inerease of the blending rate olPEG, viseosity and sofiening point inereases and penelralion and ductility deerease; the ageing performanee olPEG modified asphalt is beter than the matrix asphalt; the PEG modified asphalt under 163’℃ presents thenon-newtonian feature ; the construetion temperature of PEG modified asphalt mixture obtained through the vis.cosity-temperature curve slightly higher than the common asphalt mixlure.
