Application Technology of Thin Asphalt Concrete Overlay on Old Pavement Sheng Li 1, a, ZhaoHui Liu 2,b, XinChun Chen2,c 1Key Laboratory of Road Structure and Material of Ministry of Transport, Changsha City, China 2Changsha University of Science and Technology, Changsha City, China alishengttt@163.com, bzh2309471@yahoo.com.cn, c chenxc10@126.com Keywords: Road engineering; Thin asphalt concrete overlay; Functional recovery; Application technology Abstract.
the structural strength of asphalt pavement and deformation resistance capacity of the asphalt layer meet the technical requirements (traffic volume, weather condition and usage performance), to compare the economic and technological aspects of thin overlays program based on principals of local conditions, reasonable materials selection, saving investment, and to choose the advanced technological, safe and reliable, economical, convenient construction structural concept. 2) Follow the scientific, reliable, applicable and economic guideline, and actively, carefully promote new technology, new materials, and advanced process to earnestly pave test section and to gather experiences, make constant improvement and promote step by step. 3) Pavement structure program shall attach to pertinent regulations of environment protection, and reasonably arrange the mixing and standing position of asphalt mixture and properly deal with the old asphalt mixture waste to protect the environment and reduce
then to spray SBS modified asphalt cohesive waterproof layer on the milled road surface. 3.1Target mix design of thin asphalt concrete overlay materials Stones used for project choose sturdy andesite, whose particle shapes are very good, as they all shape like proximate square, and ore powder is replaced by cement to improve water stability and high temperature stability.

Introduction One of this treatments could be laser surface treatment, which allows modify the properties of the surface of the material without modifying the core of it.
There is an opinion that laser manufacturing techniques belong to the most promising and efficient ones, for ensuring the development in many industry branches, and especially those in which materials processing dominates.
Etching time was selected experimentally for each investigated material's surface layer form.

Depending on the wavelength of the heating laser pulse, the optical properties of materials in thin films are generally temperature dependent.
Thermal and optical properties are assumed as functions of temperature and the materials are considered isotropic.
Thermophysical and optical properties of the employed materials are reported in tables 3 and 4.

This is particularly of importance for the application of modern high-performance composite materials for safety relevant structures.
Nevertheless, modern high-performance composite materials are increasingly used in many different industries.
The structural damping coefficient (for detailed information see [9]) is set to s = 0.01 for all materials.
However, science is still at the beginning regarding a reliable prediction of the structural condition based on its E/M impedance [4].

Calibration of material types on the intensity of SMF Impacts of different materials (cartoon, PVC, wood, plastic, iron, glass, and Mild steel) on the intensity of a uniform static magnetic field (SMF) proved through designing a multi Helmholtz coil connected in series.
The results showed that the materials of a cartoon, PVC, wood, plastic, and glass have no significant impacts on the exposed magnetic field (lossless of SMF).
