中文摘要
This study was conducted to compare the results of SHRP and conventional binder tests on paving asphalts. The test results indicate that Brookfield viscosity shows a fairly strong correlation with G*/sinδ at high service temperature. Penetration shows a strong correlation with G*×sinδ at 25℃, and Fraass breaking point shows a moderate relationship with SHRP limiting stiffness temperature. The relationship between the creep stiffness and the failure strain at -12, -18 and -24℃ is very good (R2=0.81) as compared with the others. Creep stiffness decreases as failure strain increases. The Bitumen Test Data Chart (BTDC) basically allows one to take different physical property measurements (viscosity, penetration, Fraass temperature, and/or softening point) and predict the consistency of the material over a wide temperature range. Family curves of the BTDC could be used to compare the characteristics of a binder as it ages. A PG grade binder with a wide temperature range will display a low-temperature susceptibility in the BTDC.
