公路实验室沥青比对试验误差分析探讨

Discussion on Error's Analysis for the Results from Materials of Asphalt Comparison Tests Between Highway Laboratories

2000年，浙江省23个公路实验室开展了一次沥青针入度、软化点和延度比对试验，经 分析研究，得出了一些有价值的结论。

In 2000,we have a series research tests on asphalt materials comparis on 23 highway laboratory in Zhe Jiang province.Analysis the results,we have gott en many worth conclusion in penetration ,softening point and ductility for mater ials of asphalt.
