适当设计和建造的非结合骨料层有可能改善路面性能和寿命。本研究收集了关于非结合骨料的实践和研究现状的信息。这项研究的信息是通过文献综述和国家和加拿大交通机构的调查。研究发现，各州运输机构之间没有共同的做法。因此，该报告总结了与材料选择、设计和非结合骨料层施工相关的重要方面和有效做法。总结了机构的普遍做法，并强调了从研究中吸取的主要经验教训。
Properly designed and constructed unbound aggregate layers have the potential to improve pavement performance and longevity. This study gathers information on the current state of practice and research on unbound aggregate. Information for this study was acquired through a literature review and surveys of state and Canadian transportation agencies. The study finds that no common practice exists among state transportation agencies. Accordingly, the report summarizes important aspects and effective practices related to material selection, design, and construction of unbound aggregate layers. Prevalent agency practices are summarized and key lessons learned from research studies are highlighted.
