查询词典 concrete

Porous asphalt concrete is composed of asphalt mastic, coarse aggregate, thin aggregate, stuff and admixture. Such a combination is expected to fully integrate these materials. In this way, the function of interlocking among particles can be performed, a firm net of porous asphalt framework formed and the ability to resist rut and wear developed. The different mixture results in different effects; the quality is so complicated that the factors that cause damage are multiple. Therefore, it is bothersome to choose one material that can be adjusted to various conditions everywhere, such as the traffic volume, load and the weather. The current study mainly investigates and analyzes the main factor that caused flaws after the roads paved with porous asphalt concrete have been open. The analysis aims to search for the best solutions, promote the quality, prolong its availability and finally reach the purpose of complete use.

多孔隙沥青混凝土依其组成材料由沥青胶泥、粗粒料、细粒料、填充料、添加物等组成，目的是希望藉由以上材料的组合能充分接触，发挥颗粒间互锁作用，形成牢固的连锁网的沥青混凝土架构，发挥粒料本身良好的抗车辙及抗磨损之能力，因添加物的不同所发挥出的效果亦不同，其性质甚为复杂，造成损坏之因素亦属多重性，要择其适用於各地迥异之各种条件，如交通量、荷载及气候环境等因子，极为繁琐，本研究主要探讨及分析已铺筑之多孔隙沥青混凝土铺面，经通车后产生之缺失主要因素，以寻求其最佳解决方案，提升品质与延长使用寿命，进而达到全面使用。

The internal structures of geomaterials including soil, rock, asphalt concrete and cement concrete are complicated.

Pipe heat causes linesr expansion and rurtherresult in tensile stress in the direction of pipe xale to make cracks in direction perpendicular to the axle,in the case ,the stress value is obtained by ormula=E,and if ,it is estimated with 15mm LG PEX-A Pipe as base,the sectional breaking rorce is estimated approx.7.6kg/cm2,being much more little comparing with the concrete bearing force=1,536kg/cm2and its not needed to be anxious to concrete cracking rising.

由于管子的线性热膨而使管子受轴向伸长力，从人在与管轴成直角的方向上产生裂缝，这时的应力接计算，PEX－A按直径15mm标准计算进断面破坏强度约为7.6kg/cm2，比混凝土的支持力1.58kg/cm2小得多，所以不需要考虑管子对混凝土的破坏作用。
