道路建筑材料是道路桥梁工程的重要组成部分,具有非常重要的意义。本论文在分析我国对路面主要胶凝材料主要工程特性及检测手段基础上,得出工地试验室内应重点注意监测的性质指标及原材技术指标对施工的影响。本文选取水泥为主要研究对象,并选取了沥青的几项重要技术指标作了比较详尽的论述,面上基本攘括了我国高等级路面所用的主要粘结材料,具有一定的代表性。
现代意义上的水泥产生至今已有近200年的历史,其检测手段也随着社会的进步逐渐改进、完善,逐步形成了今天的检测体系。本文主要从水泥的细度、标准稠度用水量、凝结时间、体积安定性、强度等方面做了比较详尽的论述,基本攘括了道路工地试验室对水泥技术指标检测的范畴,并总结出各技术指标对施工的影响和重要性,以方便施工中对原材的重点卡控。
为使论文有一点的广度,选取了沥青几项对路面工程有重要影响的技术指标,特别是沥青的“三大指标”针入度、延度、软化点等做了较详尽的论述,沥青“三大指标”基本可以决定沥青道路路面层的可用性,有必要对此有一个深层的理解。

Road constructional materials is an important part of road and bridge engineering, has very important significance. In the analysis our country main cementitious material of pavement engineering characteristics and detection means based on site test chamber, that should be the focus of attention monitoring indexes and raw material technical index on construction effect. This article selects the cement as the main research object, and the selection of asphalt and several important technical indexes were compared in detail, face basic embedding the high grade pavement in China the main bonding material, has the certain representation.
The modern sense of the cement production has been nearly 200 years of history, the detection means also along with the progress of the society is to improve and perfect, and gradually formed today's detection system. In this paper, the fineness of cement standard consistency water, coagulation time, volume stability, strength and other aspects of a more detailed exposition, basic embedding Road site laboratory on cement technical indicators detect category, and summarizes various technical indicators of construction influence and importance, to facilitate the construction of the the original material key card control.
To make the thesis have a breadth, selects several on asphalt pavement engineering has an important effect on the technical indicators, especially asphalt "three indexes" penetration, ductility, softening point were discussed in detail, the asphalt" three indexes" basic can decide on bitumen road surface layer available, it is necessary to have a deep understanding of
