RESEARCH ON NEW TECHNOLOGY TO CONTROL HIGHWAY SEMI-RIGID BASE ASPHALT PAVEMENT CRACKS USING INTELLIGENT MATERIALS
The cost of Highway semi-rigid base asphalt pavement construction is so high and the quality problem impacts the service performance of pavement structure and the service level of the road directly,so researches on the methods of controlling pavement cracks and other diseases are always hot fields of road engineering and academic circles. It is known that the early damage of Highway semi-rigid base asphalt pavement is inevitable,the existing methods are on some degree efficient on delaying the formation and extension of cracks,but the effect is limited with different methods and various mechanisms of preventing cracks. Base on force analysis of pavement,this article presents a new technology of crack controlling which uses intelligent composite materials interlayer. By adding a stress absorbing layer between the asphalt surface layers or the semirigid base layers with low modulus,good toughness,self-adaptability and self-control ability,the intelligent composite materials interlayer has a good effect on controlling cracks which has been proved by the theoretical calculations and experimental analysis. As a result,the intelligent composite materials interlayer could efficiently prevent and delay the formation and extension of cracks,the safety and comfort of highway could be improved significantly while the cost of construction and maintenance decreasing. And the service level and social image of the road could also be improved effectively. This research has important academic and application value.
