Research on the Combination Design Method of Foam Asphalt Cold In-place Recycling Structure
Foam asphalt cold in-place recycling technology can make full use of old pavement materials to achieve low-carbon and energy-saving effects,and has been widely used in highway maintenance engineering.Aiming at the combination design methods of foam asphalt cold in-place recycling structure,this paper preliminarily introduces cold recycling design methods at home and abroad.Based on the design methods of asphalt pavement in China,it is finally suggested that the design of foam asphalt cold in-place recycling should be carried out according to the design method of highway reconstruction in China.Combined with an engineering example,starting from the foam asphalt cold recycling structure combination design and interlayer bonding design,the combination design content of foam asphalt cold in-place recycling structure is preliminarily discussed,aiming at providing reference for similar engineering design.
