Slow-down dome is widely used in rural highway security engineering due to low cost, strong deceleration performance, good quality effect. The Subject conducts the research and discussion combined with the design principles, control points of construction technology, analysis of quality inspection and evaluation and analysis on safety effect of grouted stone highway l in the security engineering of ShangShui-Quan road. This provides references for the implementation of security engineering principles which is “Safe, effective, suit measures to local conditions”. In March 2012, the Ministry of transport of rural highway construction and maintenance management work conference put appeal about " let peasants go on road safety assured way, strengthen the rural highway security infrastructure ". In order to carry out the security engineering construction principles about conference proposed “safe, effective, economic, practical" rural road, Tianjin Municipal Highway Administration Bureau set up “the implementation of technical guidelines of Tianjin city rural highway traffic safety facilities” science and technology project research group to research demonstration. This paper conducts practice of argumentation combined with quality stability, practicality, operation process safety of Caigou Road security engineering being aimed at Belgium pavement; it provides technical supporting for the further promotion of the subject.

Traffic signs are widely used in rural highway security engineering due to low cost, strong directive performance. The paper conducts the research and discussion combined with the design principles, control points of construction technology, analysis of quality inspection and evaluation and analysis on safety effect of traffic signs in the security engineering of Cai-Gou road. This paper provides references for the implementation of security engineering principles which is safe, effective, economic, practical.
