基于HWD的公路飞机跑道道面承载能力测试分析

为了对北方某公路飞机跑道的承载能力进行分析评定，根据设计使用飞机主起落架及其滑行轨迹横向分布规律，并综合考虑汽车轮迹规律，提出了现场测试方案。选取重型落锤式弯沉仪法（HWD）和承载板法进行了现场试验，通过对沥青道面的弯沉和模量等指标进行对比分析，发现弯沉值存在相关性，与公路相关研究结论吻合，动模量数值约为静模量的2倍。又用HWD测得的结果按民航规范推荐的方法计算出该道面的PCN值，依此作为承载能力的评价结果，计算当量道面剩余累计作用次数为33368118次。

Test and Analysis on Bearing Capacity of Highway Runway Asphalt Pavement Based on HWD

In order to analysis the capacity of one highway runway in north, according to the type of main landing gear and its glide trajectory transverse distribution, and considering about the distribution of car wheel trace, field test scheme is put forward. Heavy weight deflectmeter method and bearing plate method is tested in field test, according to comparative analysis the correlation of deflection between this two methods is found, the results correlate well with related research in highway, at the same time, the results show that dynamic modulus is about double of static modulus. According to the civil aviation specification method with heavy weight deflectmeter test results to calculate the pavement classification number as pavement bearing capacity evaluation results, and the equivalent pavement residual multiplication of cumulative of this highway runway is 33368188.
