Calculation of Emission Reduction Benefits of Fully Deep Cold Recycled Asphalt Pavement Maintenance Technology
To truly reflect the energy-saving and emission reduction benefits of the full depth cold recycled asphalt pavement maintenance method,a life cycle analysis method is used to divide the construction process of the full depth cold recycled asphalt pavement into three stages:raw material production,material transportation,and on-site construction.A calculation method for carbon emissions of the full depth cold recycled asphalt pavement is established,combined with the Tianjin Avenue maintenance project as example,and comparing with the commonly used plant mixed cold recycled asphalt pavement and milling and resurfacing methods to quantify the emission reduction benefits of the full depth cold regeneration method.The results show that compared with the plant mixed cold regeneration method,the total deep cold regeneration scheme reduces emissions by about 3.54kg/m2,with a reduction rate of 35.22%.Compared with the milling and resurfacing method,its emission reduction is about 11.88kg/m2,and the emission reduction rate can reach 64.63%,with significant energy-saving benefits.
