Abstract

The stability of the bond between the cement concrete slabs and asphalt concrete overlay is guaranteed plus pave the way for a critical surface road performance, which is heavily influenced by the inter-layer performance. Countries cement asphalt pavement overlay technology a lot of research, and also made some achievements. But study interlaminar Treatment is still not enough depth and perfect, especially in cold regions with lower winter temperatures, plus resurfacing low temperature impact, easy to produce reflective cracking and other diseases, pressing need scientific and effective layer Treatment technology to improve road performance. Extensive analysis of the information on the basis of the existing layer between Treatment Cold Regions paved asphalt pavement actual project status, in-depth study of the the old Cold Regions cement overlay asphalt pavement Treatment methods and theories, the assurances cold areas good road performance technology layers of old cement asphalt pavement overlay. This paper studied the contents of the following aspects: (1) System survey analysis of Jilin Province, climatic conditions, road surface temperature, road traffic and the old cement overlay asphalt pavement condition, research cold cement overlay asphalt pavement . (2) add to pave the way for cold regions surface damage conditions, in-depth analysis of each evaluation method presented matter-element model to evaluate the use of improved and resurfacing damage situation;, combined with the results of the evaluation, the evaluation section of the actual situation, research in cold regions overlay pavement damage causes and preventive measures and to provide a basis for cold regions plus resurfacing. (3) For the cold zone temperature condition, the study interlaminar state, by calculating the temperature stress of the overlay, the overlay temperature - load coupling stress and interlaminar shear stress, the internal forces of the study plus resurfacing affected by temperature obtained stress with stress-absorbing layer modulus and thickness, plus the variation of the modulus and the thickness of the ply; combined with the state of the individual layer influencing factors and conditions the interlaminar state grading; research in cold regions at the same time applicability and performance of low temperatures lower materials and to provide a basis for inter-layer design. (4) a large indoor reflective cracking full-scale test, determine Reflective Cracking Resistance of various types of layer materials, and indoor low-temperature tensile test depth study on the performance of the interlayer material combinations; calculate the surface temperature at the bottom - load coupling tensile stress, tensile strength of the surface were compared, and material combinations grade material combinations put forward all kinds of cement overlay asphalt pavement conditions and levels of inter-layer between the application layer of the working state, to protect the old Cold Regions The cement road asphalt overlay Road with the performance. (5) Analog cold areas the actual road conditions, load type, temperature type reflective cracking indoor test, direct shear and pull-out tests, shear, cement and material combinations between the various types of layers of cold regions Shop Asphalt Pavement Reflective Cracking ability and bonding properties of sandwich crack resistance, shear adhesion effect validation preferred best inter-layer materials and structures provide the basis for all types of cement asphalt pavement overlay.
