摘要
利用国产车辙试验机,参照日本沥青路面规范中推荐的方法,对沥青混合料进行车辙试验。结果认为,严格控制温度是试验成败的关键;控制轮荷重比控制单位轮压更合理可靠;用第30分钟的变形量比用初始变形作为补充指标更为适用。
Referring to the method recommended in Japan's asphalt pavement
specification,the wheel tracking tests of a batch of bituminous mixture were carried
out with test machine made in China.The test results showed that to strictly control
the test temperature is a key to obtain reliable results.The tests also showed that the
control of wheel loading is more reliable than the control of wheel unit pressure.As
a suplementary test index,the 30th minute deformation is more preferable than the
initial deformation.
