对沥青路面质量控制过程中取样方法的思考

Considerations on Sampling Method for Quality Control of Asphalt Pavement

沥青混合料和沥青路面取样方法是沥青路面质量控制的第1步,取样是否具有代表性、能否反映路面实际情况是质量控制的关键。分析我国现有取样方法,介绍随机取样法,提出在沥青路面施工质量控制中采用分层随机取样法的思路,并举例说明如何运用分层随机法对沥青混合料和路面芯样进行取样。

the sampling method for bituminous mixture and bituminous pavement is the first step for quality control on asphalt pavement. Whether the sampling is representative and whether it can reflect the actual condition of the pavement are the keys for quality control. This paper analyzes current sampling methods in China, introduces random sampling method, proposes application of stratified random sampling method during asphalt pavement construction for quality control, and illustrates how to carry out asphalt mixture sampling and pavement core sampling in the method of stratified random sampling method with examples.
