| 摘 要： | 低温开裂是沥青路面早期损坏的主要现象之一。随着对路面使用性能的要求不断提高,低温开裂问题也越来越受到道路工程研究者的重视。同时,建立准确的低温开裂预估模型也是寒冷地区沥青路面结构选择与材料设计的基础。低温开裂预估模型主要包括力学经验模型与统计模型两类。本文是以加拿大学者Haas提出的低温开裂统计模型为基础,针对我国的道路状况补充并完善了Haas低温开裂预估模型,并通过试验路的裂缝调查研究,分析了低温开裂预估模型的适用性,可为我国沥青路面低温抗裂设计提供参考。

| Abstract: | Low-temperature cracking is one of the main early-damage types of asphalt pavement.More and more experts are concentrated on the low temperature cracking problems of asphalt pavement.At the same time,the cracking predicting model is the basis of the(structure's) selection and material's design of asphalt pavement in cold areas,which includes mechanics-empirical model and statistics model.This study is based on Haas model,with modification to the Haas predicting model for use in China.By use of actual cracking(data) from survey and study,the adaptability of the Haas model to asphalt pavement cracking predicting in China is discussed. |
