Standard Practice for Developing a Quality Assurance Plan for Hot-Mix Asphalt (HMA) 制定热拌沥青(HMA)质量保证计划的标准实施规程
AASHTO R 42-06(2020)为HMA路面的控制、验证和验收提供了必要的质量保证计划。它包含质量控制和验收的要求。本标准实施规程为质量控制计划提供了框架,该计划为与HMA生产和放置相关的承包商质量控制(QC)系统制定了最低要求和活动。这些要求包括证明材料和产品符合规范所需的检查和测试清单。现场质量控制的主要方法是使用Superpave旋转压实机并评估混合料的体积特性。该标准实践还为一个计划提供了框架,该计划为机构评估和验收HMA项目确定了验收要求。
AASHTO R 42-06 (2020) provides the necessary quality assurance plan for control, verification, and acceptance of HMA pavement. It contains requirements for both quality control and acceptance.This standard practice provides framework for a quality control plan that establishes minimum requirements and activities for a contractor's quality control (QC) system related to HMA production and placement. These requirements include a listing of the inspections and tests necessary to substantiate material and product conformance to the specifications. The primary method of field quality control employs the use of the Superpave gyratory compactor and evaluation of the volumetric properties of the mix.This standard practice also provides framework for a plan that establishes acceptance requirements for an agency's assessment and acceptance of an HMA project.
