查询词典 asphalt cement

Based on the research, results from home and abroad, according to the characteristic of the widely-adopted semi-rigid pavement, the thesis studies the cold in-place recycling technology, and proposes the method of the mixture design of cold in-place recycling, the reasonable ratio of the pavement to the base and the amount of cement utilized. Moreover, the thesis delves on the mechanical property, construction craft and quality control of the old asphalt mixture after recondition, how to apply the recycling mixture to the base, and cater to the needs of performance.

Bases on infrared spectroscopy analysis,X ray diffraction analysis and scan electron microscopy,an investigation was made into the microstructure characteristics of cement asphalt emulsion mastic and concrete interface.

使用红外光谱、X衍射和扫描电子显微镜，研究了水泥乳化沥青胶浆以及混凝土界面的微观结构特征。

The internal structures of geomaterials including soil, rock, asphalt concrete and cement concrete are complicated. The internal constitutions and structure of a geomaterial determine die stress and strain distribution and control the failure mechanism and process of that geomaterial when it is subject to loading.

土、岩及混凝土是一种内部结构极其复杂的材料，内部细观组成和结构决定了它们在外力作用下内部应力和应变等物理场的分布状态，在很大程度上控制了它们的宏观力学响应和破坏机理和过程。

Based on the literature review, this paper analyzes and investigates the development and status of digital image processing techniques in quantitative analysis and associated numerical simulation of the geomaterials. It includes quantitative analysis of particle shapes, quantitative analysis of internal structures of soil, rock, asphalt concretes and cement concrete, quantitative analysis of macro-structures of rock mass in the ground, and numerical modeling and simulation of geomaterials by taking into account their actual internal structures, Based on the review results, the paper discusses the development history and future trend of the utilization of the digital images and associated techniques in soil and rock.

本文在研究相关文献的基础上，分析和研究了数字图像技术在土、岩及混凝土内部结构定量分析和力学数值计算中的发展过程和研究成果，内容包括：单个骨料颗粒形态特征定量分析；土、岩和混凝土内部结构定量分析；岩体结构定量分析中的应用；基于数字图像处理的土、岩和混凝土细观结构力学计算。
