| Since the reform open, our country of the highway transportation business enter the fast development a new period, high-speed.The development of the road also at be close to 20 in the last yearses from did not have, experience from 0 mileages to the fast development process of more than 40,000 kilometers, carry the increment and vehicles of the quantity to overload increasingly and seriously along with the tra- nsportation at the same time.The thesis is text passes various ex- periment research that anticipate( SMA) to the asphalt horse's hoofs fat crushed stones admixture, passing at the same time to.It matches with the design and experiments of the ratio, thus analyzed SMA heat stability, low temperature anti- snap, the anti- jelly and good roads such as its stability of water and enduring sex etc. The experiment the road to carry on the actual verification through severals, the first step obtained can pleased result, other roads concerning the asphalt horse's hoofs fats use the function and will still continue to open the exhibition research.Aim at the present condition that the special weather, the geography environment and the highway asphalt roads of my province face, combine its another country.The asphalt horse's hoofs the fat crushed stones of the house and other cities mixs with the research for anticipate, in experiment and practice the quest suits me fine the province circumstance of the road that the asphalt horse's hoofs the fat crushed stones mixs with to anticipate face, constuct for the highway engineering of my province future and the research, design...etc. provide the precious data and related basises.Carry on the special subject research to the technical road of SMA with the function, have some difficulties of the issue to application to ask in the process .Did in experimenting the foundation of the foundation of the data and the research argument answer.Tally up the experience of my province, go together with from the design, class, the construction craft, quantity management, settle sum etc. put forward one whole set of method, promote once to the tech- nique of SMA;At the same time, practice to have to my province eng-ineering stronger aim at the sex and function, will make my province apply that technique to have necessarily an overall of, the quality leap;Make my province of asphalt road face the quantity contain a widespread exaltation, producing the economic performance and social performances of show the remarkables.Therefore for research the SMA road has the realistic meaning with the function.For the sake of the experience that the system tallies up my province in the applied technique of SMA, teach and study the result, the design and the construction methods that the norm SMA road face, push this technique application in my province highway actively and steadily, the province transportation hall according to my province and local experiences and the research result.This text aims at the asphalt hoof fat( SMA) on trial to try out with engineering, adopting the method that concrete experiment and the theories qualitative analysises combine together, carrying on the research analysis to the road of the asphalt hoof fat with sex, getting the functions, such as its anti- heat, resistant to cold, anti- jelly and the water stability...etc..Do to experiment as follows:1, the asphalt, stone anticipate, the single quality experiment of etc. of plain fiber of the wood quality.2, mix with to anticipate the class to go together with to experiment, the admixture that among them have the thick a path of one to gather to anticipate anticipates to experiment:Matthus experiments the di- fferent from the car experiment, anticipate above-mentioned two ex- perimentses that the dissimilarity that the class go together with do according to the bone, obtain result to carry on the analytical summary, thus carrying on SMA mineral's anticipate and going together with to really settle.Pass the superiority to as above of the laboratory experiment and the experiment of the road segment on the scene, the data analysis studies behind the road that the asphalt horse's hoofs fat crushed stones mixs with to anticipate uses the function, namely:The anti- heat, resistant to cold, anti-jelly, the antislippery and water stability etc.s have other superior sex that the structure can't compare to. |
