In order to improve the pavement anti-crack performance of semi-rigid base of express-way,and postpone the development of the reflective crack.JiangSu constructs a large number of test sec-tion in terms of different anti-crack measures.Base on the LTPP,chose the typical crack section and de-sign observation scheduler of the matching solutions.By the evaluation of the effects of anti-crack meas-ures,put forward the conditions of specific measure,and provide reference for similar projects with the methods of long-term follow-up observation.%为提高高速公路半刚性基层路面结构的抗裂性能，延缓反射裂缝的发展，江苏省针对各项抗裂措施铺筑了大量科研段。基于 LTPP 研究方法，选择典型抗裂科研段，设计配套性能观测方案，通过对于目标科研段的长期跟踪观测，研究评价各项抗裂措施的工程效果，针对性提出各项抗裂措施的工程适用性条件，可为同类工程提供参考和借鉴。
