前言
原中华人民共和国行业部标准《公路沥青路面施工技术规范》(JTJ 032-94)（以下简称原《规范》）于1994 年6 月7 日发布，1994 年12 月1 日实施。规范在保证沥青路面的建设质量方面起到了重要的作用。但是我国公路建设的发展速度很快，1994 年规范修订时，我国高速公路还刚刚起步，1993 年仅建成通车里程1130km。到2003 年，高速公路的通车里程已经接近3 万公里，其中绝大多数是沥青路面。在交通快速发展的新形势下，国内外公路建设发生了许多新的变化。
国际上随着美国SHRP 研究成果SuperpaveTM及欧洲CEN 沥青及沥青混合料研究成果的发表，世界各国对沥青路面的研究都更深入，得出了许多十分重要的新成果，不少国家对相关规范进行了适当的修改。涌现出一些新的筑路机械，新的施工工艺都不同程度地影响到我国。在我国，通过国家科技攻关等一系列科学研究及长期的施工实践，对沥青路面的各方面都有了新的认识。原《规范》已跟不上公路建设的需要，为了适应新的要求，再次进行了修订，制定了《公路沥青路面施工技术规范》（JTG F40-2004）（以下简称本《规范》）。
为了对与规范相关的主要技术问题进行研究，交通部先后组织开设了一系列研究专题，包括“沥青混合料矿料级配及配合比设计方法的修订”、“沥青路面透水测定方法及指标要求”、“超重载交通沥青路面材料试验标准(GTM 对比)”、
“SUPERPAVE 设计方法的引进与开发”、 “高速公路沥青路面抗滑技术标准”、“沥青混合料水稳定性评价指标” 、“道路用乳化沥青技术要求的修订”等，许多省、
市、自治区也开设了相关的研究专题，均取得了许多有重要价值的成果，为本规范的修订提供了技术依据。同时本规范与相关规范的修订进行了充分的协调、统一。
因此，本《规范》是在原《规范》的基础上，合并了《公路改性沥青路面施工技术规范》及《公路沥青玛蹄脂碎石路面技术指南》的相关内容，并针对主要技术问题开展了科学研究与试验验证工作，充分吸收了各专题的研究成果，经广泛征求意见后制订的。
这次修订的主要内容有：
(1)在“ 八五”国家科技攻关成果的基础上，提出了新的道路沥青标准和沥青路面的气候分区。提出了按照当地气候条件及交通情况(公路等级)选择沥青标号的方法。
(2) 在总则中强调了几个与早期病害有关的措施，如防治层间污染、合理工期、路基不均匀沉降等等。
(3)在材料部分全面修订了道路石油沥青、乳化沥青技术要求，局部修订了集料技术要求。
(4) 针对改性沥青和SMA 方面的一些特殊要求进行了补充完善。
(5)明确了三层矿料级配范围的意义，修订提出了规范矿料级配范围，调整工程级配范围的原则。
(6)完善了沥青混合料配合比设计方法，调整了马歇尔试验配合比设计方法及设计指标、标准，修订了确定最佳沥青用量的方法，统一了空隙率等体积指标的计算方法。
(7)修订并补充了沥青混合料配合比设计检验方法和技术要求，增加了渗水性检验指标。
(8)调整了不同粒径混合料的适宜的压实层厚度，不同层位的沥青混合料种类、
规格。明确施工期间需要对设计结构、材料进行审查和监督，予以确认。
(9)在施工工艺部分，主要修订了对拌和厂的要求，提出了过程控制、总量检验的方法，增加了提高平整度的措施，强调了摊铺宽度限制和加强轮胎压路机压实等内容。强调了冬季施工及雨季施工的问题。
(10)修改了透层、粘层、封层的内容。将封层部分移入表面处治一章中，并增补了有关稀浆封层、微表处等新型结构的内容。
(11)修订了施工质量检验指标、频度、方法，增补了密水性(渗水系数)要求，强调压实度检验主要是工艺控制、淡化了钻孔。
(12) 修订了桥面铺装的厚度、混合料类型，施工工艺。提出了对钢桥面铺装的基本要求。
本次修订时重点对高速公路、一级公路提出更高的要求。许多条款对不同等级的公路明确提出了不同要求。
各单位和个人对本规范有何意见或建议，可与规范编制单位联系，以便下次修订时参考。
