Abstract

In recent years, the linear amplitude sweep test (LAS) and the time sweep (TS) test under dynamic shear are widely used to evaluate the damage resistance of paving asphalt. This paper attempts to demonstrate the possibility of using the LAS test as the accelerated fatigue protocol for damage resistance estimation of asphalt from perspectives of crack initiation and propagation. Both the finite element (FE) simulation and experimental work based on fracture mechanics are conducted for this purpose, followed by the verification on the traditional TS fatigue test. The FE model of the cylindrical asphalt sample is created by means of the FRANC2d/L software to identify the cracking mode under the crack propagation phase. The LAS test results show that the damage evolution behavior follows the two-phase crack growth (TPCG) model and the crack propagation is governed by mode-I cracking, which is consistent to the FE-based numerical simulation. The TS test results show that the TPCG model in the LAS protocol can be utilized to reasonably distinguish the crack initiation and propagation resistance of different asphalts. The polymer modification on asphalt can significantly improve its fatigue damage resistance.

线性振幅扫描作为加速疲劳协议在沥青粘结剂损伤抗力估计中的验证

近年来，动态剪切作用下的线性振幅扫描试验（LAS）和时间扫描试验（TS）被广泛应用于路面沥青的抗损伤性评价。本文试图从裂纹萌生和扩展的角度，论证LAS试验作为加速疲劳试验估计沥青损伤抗力的可能性。为此进行了有限元模拟和基于断裂力学的试验工作，并对传统的TS疲劳试验进行了验证。利用FRANC2d/L软件建立了圆柱形沥青试样的有限元模型，以识别裂缝扩展阶段下的裂缝模式。LAS试验结果表明，裂纹演化行为遵循两相裂纹扩展（TPCG）模式，裂纹扩展受i型裂纹控制，与有限元数值模拟结果一致。TS试验结果表明，利用LAS协议中的TPCG模型可以合理区分不同沥青的裂纹起裂和扩展阻力。高分子改性沥青可显著提高其抗疲劳损伤性能。
