Abstract

With the developing quickly of the world economy and rising of automo-tive industry, the road has already become the economic lifeline of the most countries,, the road transpo-rt has been the important transport means of a national economy development.Thepaveme-nt is the most importantly constitutes part and most engineering structure in the whole road, its investment the comparison have usually can attain 10%～30% in the road the construct-ion the expenses, is an extremely considerable property.The quality of the pavement condi-tion will directly influence the whole road system’s development in the social economic performance and the national economy.The evaluation of the cement concrete pavement performance is a topic which has a tenacious theories innovation and practices operability.Because the each section uses the purpose of evaluation and the evaluation result have lay particular emphasis on, so its eval-uation method and the evaluation index be not perfect either, many important problems still need to be practiced quest and theories to study.Different section to the sele-ction of evalu-ate index and power be heavy to really settle inconformity, there is no the evaluation met-hod, exist a management to disorder and protect can not compare with of problem, cause the some teilstreck seriously influence the ability of whole road to go through.The pavement performance is mainly decided by the pavement structure potential,and the structure potential can be the indirectly reflected by the pavement damaged degree;The pavement breakage is divided into damaged two major typeses:material breakage and stru-cture.In the evaluation of the cement concrete pavement performance, to the structure pote-ntial of pavement, the riding quality index, safe function is an all indirect and synthetic ind-ex.The cement concrete pavement situation on road assesses to mainly use structure condi-tion, surface function condition, strength condition three index signs to reflect.Among them, structure condition from rupture condition, doweling capacity and slab suspension conditi-on three index to come to indirect reflection, surface function condition from the riding qu-ality and skidding resistance indirectly reflect and the strength condition was folded fun-ction and structure by the anti-just a degree two index signs to come to indirect reflection.This paper takes The Technique of Thin Cement Concrete Pavement Quickly Maintains On The Highway Roadbed Sinks About Rigid Road and The comprehensive Technique Research On Village Highway of Plateau Mountain Area In Yunnan actual engineering as to rely on, sets up the evaluation index of a set of science system and evaluate standard, and the main force holds in the process of study with science development view is instruction, tring hard for in the cement concrete pave-ment to use function to evaluate of rely on and practice aspect, investigate to give attention to both system, science and the valid method of maneuverability, make research result can as soon as possible convert into compare norm of, convenient of with can operate of evalu-ation system;But the theories evaluated in the function of the cement concrete pavement research aspect, then try hard for to attain point of departure, visual field breadth, apocal-ypse many, have prospect, possibly provide some experienced turn the principle or way of thinking of research.The textual and main contents include:(1)The classification and ratings of the cement concrete pavement damage;(2) Selection and data which evaluate index coll-ect a method to really settle, and adopt layer analysis a method to make sure evaluation index power;(3)Select a suitable evaluation method certain comprehensive evaluation mod-el;(4) The development of evaluate system;(5)The adoption relies on an engineering data, verification evaluation the rationality and maneuverability of the system.
