自1967年以来，TRL一直在研究多孔沥青作为路面材料，现在已被纳入公路工程规范和道路和桥梁设计手册，由运输部和其他英国主干道监督部门出版。从广泛的道路试验中获得的经验进行了审查，并提出了建议，以帮助那些参与设计，制造和应用多孔沥青，特别是20毫米标称骨料级配的人。道路试验是根据多孔沥青层的设计和施工来解释的；材料所能达到的性能；以及它的使用对维护的影响。道路试验表明，如果设计和建造得当，并铺设在合适的地点，多孔沥青可以持久耐用。在这种情况下，多孔沥青可以提供表层材料所需的标准性能（如抗滑性、纹理深度和轮廓），以及通过减少噪音和喷雾带来的额外好处。讨论了不同于传统不透水路面的多孔沥青养护方面的问题。(一)
Porous asphalt as a road surfacing material has been under investigation by TRL since 1967 and is now included in the Specification for Highway Works and the Design Manual for Roads and Bridges published by the Department of Transport and the other Overseeing Departments for UK trunks roads. The experience gained from extensive road trials is reviewed and recommendations are derived to assist those involved in the design, manufacture and application of porous asphalt, particularly with a 20 mm nominal aggregate grading. The road trials are interpreted in terms of the design and construction of porous asphalt layers; the properties that can be achieved from the material; and the maintenance implications of its use. The road trials have shown that porous asphalt can be durable if it is properly designed and constructed and it is laid on suitable sites. For such situations, the standard properties required of surface course materials (such as skid-resistance, texture depth and profile) can be provided by porous asphalt, together with the additional benefits through reduction of noise and spray. Aspects of maintenance for porous asphalt that are different from that of traditional, impervious surfacings are discussed. (A)
