Research on structural composition of Long-life Asphalt Concrete Pavement

Combined with the actual case of Punan highway, Long-life pavement structures are analyzed, and the engineering economic cost benefit ratio method and net present value method are applied for the economic benefit analysis. The conclusion is as follows: The research on the asphalt concrete long-life pavement structure includes a complete set of technology, such as the structure, material, construction and economic benefit analysis, and is a complete research system. We should choose the best solution after we fully consider all the factors affecting the economic benefits when we make the decision-making for the pavement structures.
