Of Cement Stabilized Gravel Crack Resistance Applied Technology Research

The cement stabilization stone packing by it high intensity, the good water stability and the board character, obtained the widespread application in our province highway construction, but the early crack appearance, as well as causes from this the bituminous pavement reflection crack appearance, affects the path seriously smoothness and travel comfortableness, has enlarged the maintenance fund investment, posed the threat to the path durability. How after the present research mostly is solves the cement stabilization stone packing crack to appear prevents or the reduction to the bituminous pavement reflection crack, but very little bond timber structure itself and the construction technology synthetic study reduction cement stabilization stone packing crack produces means.In order to enhance the cement stabilization stone packing crack resistance energy, this article mainly carries out the research from following several aspects:1. Through represents the road section to the bituminous pavement cement stabilization stone packing crack on-the-spot investigation and the scene examination result generalized analysis research, the analysis surface check plant disease basic reason, the cement stabilization stone packing crack material structure composition aspect reason and the construction craft reason, the determination research key;2. Through to the cement stabilization stone packing material composition structure and the gradation theory research, the preliminary determination has the crack resistance to be able the cement stabilization stone packing skeleton dense texture material composition design method;3. Experiments the confirmation skeleton dense texture cement stabilization stone packing through the room in the crack resistance energy; And through mechanics, anti-frozen, the anti-washout, anti-weary and so on the aspect fundamental researches and the experimental contrast, the confirmation crack resistance skeleton dense texture compares the conventional structure cement stabilization stone packing to have a better road to use the performance;4. Through segregates the control engineering research to the crack resistance cement stabilization stone packing construction in, further controls the cement stabilization stone packing crack from the construction technology aspect the production. Through experimented the road the observation further to confirm the research results reliability.The cement stabilization stone packing material crack resistance can first be decided the material the composition structure.Because the skeleton dense cement stabilization stone packing material the aggregate forms the skeleton structure to inlay mutually pushes has the big angle of internal friction, the binding dense packing has in the big cohesive force, the aggregate the coarse aggregate content are many, fine aggregate content few, between aggregate pellet mortar content few and so on material structure characteristics. Therefore the skeleton dense cement stabilization stone packing material has the remarkable crack resistance energy, more superior mechanics performance, good fatigue resistance, anti-washout, water stability and frost resistance. This article also carries on the research analysis from the influence cement stabilization stone packing quality stable construction link, proposed the cement stabilization stone packing construction segregation control technology method, this regarding guarantees the skeleton dense texture cement stabilization stone packing crack resistance to be able the realization has the important guiding sense.The experimental road result indicated that, the skeleton dense cement stabilization stone packing crack resistance can by far surpass the existing standard aerosol dense cement stabilization stone packing, the dehiscence spacing big extension, crack quantity reduces approximately 77%, has achieved this article anticipated research aim.
