沥青混合料抗剪切强度现场检测设备是基于在单轴贯入试验方法的基础上研制的现场检测设备,具有体积小、重量轻、便于携带特点,可精确控制加载速率。该设备以1mm/min、5mm/min、10mm/min的加载速率进行沥青混合料贯入强度试验,其试验数据的变异系数分别为3.76%、7.41%、5.10%。试验表明沥青混合料抗剪切强度现场检测设备的稳定性能良好。 Asphalt anti-shear strength on-site testing equipment is based on the uniaxial penetration test method developed on-site testing equipment, with small size, light weight, easy to carry, can accurately control the loading rate. The penetration strength of asphalt mixture was tested at 1mm / min, 5mm / min and 10mm / min. The coefficient of variation (CV) of the test data were 3.76%, 7.41% and 5.10% respectively. Tests show that asphalt concrete shear strength on-site testing equipment stability is good.
