At the end of 2012, the number of national civil motor vehicle has reached 109.33 million, with an increase of 16.9%, and 88.39 million private cars, with growth of 20.6%[1].

For many engineering materials, further improvement of their properties through a modification of their microstructure, chemical composition, and phase composition, is practically impossible.
In this situation, the most effective way of to improve the mechanical properties of various engineering components is the modification of surface properties by the deposition of PVD (Physical Vapour Deposition)/ CVD (Chemical Vapour Deposition) coatings [1, 2, 3].

The Results of the Test Data Effectively Conduct the Construction (1)Lab test data: this is the fundamental test results that guide the construction and ensure the engineering quality.The test data includes raw material test results,mixture design,standard compaction test results, seven days unconfined compressive strength test, split test, shrinkage test results and so on.
Supervision unit must play the supervisory role to ensure the test data real and effective so that engineering quality could get effectively guidance and regulation; (2)Field test data: the first is the paving section of roadways,this is the forerunner of paving work, its purpose is to summarize and determine various parameters in the construction process,including Rolling thickness,whether to need to determine the thickness with layered paving,determine coefficient of loose paving, detection of compactedness,etc.
