用于路面的混凝土混合物具有不同于其他类型混合物（如结构混凝土或大体积混凝土）的用途和所需特性。因此，有必要为特定于铺路的混凝土混合物设计指南，如公路、街道、机场和停车场。本指南描述了水硬性水泥混凝土的混合料设计和试验混合比选择方法，该混凝土由辅助胶凝材料、化学外加剂和纤维制成，也有辅助胶凝材料、化学外加剂和纤维制成。本指南提供了一种方法，侧重于在路面结构设计、混凝土生产、施工操作和路面所处环境的背景下设计混凝土混合料。 试拌比例适用于由正常重量骨料和混凝土组成的混凝土，其和易性适用于各种类型的路面施工，如滑模、固定模板和激光导向找平。该方法提供了拟分析的比例的初始近似值，以评估其在混合、运输、浇筑、熨平板和加固、饰面、纹理和凝固时间方面的性能潜力。该方法还考虑了硬化混凝土的强度、耐久性、耐磨性、防滑性、平整度、尺寸和形状稳定性等性能参数。包括在给定施工环境中检查材料不相容性的方法，以及骨料级配优化的方法。 应通过在实验室、然后在现场制备和分析试验混合料，并根据需要进行调整，以产生所需的混凝土特性，来检查产生的配合比。本文件不包括特殊混凝土路面混合料，如透水混凝土或碾压混凝土。这是一份双单元文件；然而，以英寸-磅和国际单位制表示的成对值通常不是完全相等的。因此，任何一种系统都应独立于另一种系统使用。

Concrete mixtures intended for pavements have purposes and desired characteristics that are different from other types of mixtures, such as structural or mass concrete. Thus, a guide for designing concrete mixtures specific to paving, such as highways, streets, airfields, and parking lots, is necessary. This guide describes a method for designing mixtures and selecting trial mixture proportions for hydraulic-cement concrete made with and without supplementary cementitious materials, chemical admixtures, and fibers. The guide provides a method that focuses on designing the concrete mixture in the context of pavement structural design, concrete production, construction operations, and the environment in which the pavement will reside. Trial mixture proportions are for concrete consisting of normalweight aggregates and concrete with workability suitable for various types of pavement construction, such as slipform, fixed-form, and laser-guided screeding. The method provides an initial approximation of proportions intended to be analyzed to assess their performance potential for mixing, transporting, placing, screeding and consolidating, finishing, texturing, and time-of-setting. The method also considers the hardened concrete performance parameters of strength, durability, abrasion resistance, skid resistance, smoothness, and dimensional and shape stability. Methods of checking for incompatibilities of materials in given construction environments are included, as well as methods for aggregate grading optimization. Resulting proportions should be checked by preparing and analyzing trial mixtures in the laboratory, then in the field, and adjusting as necessary to produce the desired concrete characteristics. Special concrete pavement mixtures, such as pervious concrete or roller-compacted concrete, are not included in the document. This is a dual-unit document; however, paired values stated in inch-pound and SI units are usually not exact equivalents. Therefore, either system should be used independently of the other.
