摘要
介绍了CPN这种便携式车辙仪的性能参数和与现有车辙试验机的区别,并通过材料试验评价CPN车辙仪用于高等级沥青砼路面高温性能评价的适用性,并尝试得出与常规车辙试验动稳定度一致的计算公式.通过研究发现,CPN车辙仪用于沥青混合料高温稳定性的评价是可行的.
The paramneter of CPN,a kind of hold type rutmeter instrument, is introduced as well as the differences between the CPN and the existing rutmeter. The applicability of CPN rutmeter used for evaluating the rut-resistance property of high grade hot mixed asphalt mixed pavement was tested and assessed through a material experiment. The calculation formula that was in accordance with the normal rutmeter experiment was managed to get. The CPN used for the rut-resistance property evaluation is feasible through the control experiment.
