Abstract

To enhance the economic, social development, political, overall performance and social functioning of every society, the degree, and efficiency of road networks play a crucial role. For any community, it is impossible to have overall social growth without a good transport network. In the manufacture and service of road networks, we are constantly looking for solutions to enhance pavement performance, improve construction efficiency and improve environmental protection. The use of additives can effectively improve the quality of asphalt pavement, prevent cracking, enhance water retention, enhance the stability of production and construction suitability, increase strength, and enhance the adhesion of the surface and other good effects. Moreover, different modified asphalt mixtures need to be handled in an environmentally appropriate manner to avoid the negative impacts of their construction, so the approach of LCA was used to evaluate the construction processes. Recently, numerous LCA studies have discussed the environmental implications of road construction activities worldwide, but there are still several issues that need to be further examined. This paper explains an overview of the application of the LCA methodology and its implementation in road construction.
