Study On Cement Stabilized Gravel Materials Design Based On Vibrating Molding

Due to Cement stabilized gravel base its good road performance, it is widely used inhighway construction in our country. However, because of its strongly sensitivity totemperature and humidity, it causes the cracking of asphalt pavement, forms a series ofdisease which is given priority to with reflective crack, shorten the service life of the asphaltroad surface, reduce the reliability of the pavement structure, and to some extent, restrictedthe healthy development of the highway traffic in our country. In recent years, with thedevelopment of transportation in our country and the improvement of construction technology,the indoor test method can’t reflect actually material’s real performance, therefore, study oncement stabilized materials design based on the vibrating molding is of great significance.Paper by analyzing the vibration compaction principle and working principle of thevibration compaction meter, determine the reasonable vibration parameters. Based onvibration test method, gradual filling method and I method to determine the multilevel densebuilt-in graduation, and through fractal theory research, to determine the level of the cementstabilized gravel, proposed to the double dynamic balanced parameter D-R as the index ofcement stabilized gravel gradation. By compact vibrating compaction method with heavycompaction method show that the vibration method is used to determine the compactionstandard has obvious advantages. Analysis and study mechanics strength of the based on thevibration molding cement stabilized gravel, and the mechanical properties of modulus ofresilience, reveals the influence law of various factors, strength forecast equation, anddetermine the linear relationship among of them. By splitting fatigue test, built the fatigueequation. Based on Mohr strength theory, analyze the cement stabilized gravel’s internalfraction resistance and cohesive force, then puts forward the evaluation index of the shecement stabilized gravel structure, friction-resistance ratio C=φz/φj, and determine thereasonable scope of C. By splitting fatigue test, bulit the fatigue equation of the cementstabilized gravel, according to the theory of correlation coefficient of correction.
