This case analyzed the energy consumption and carbon emissions of highways cement pavement structure and asphalt pavement structure during their life cycle under the same traffic volume and weather conditions and demonstrated the reliability of the calculation results.

With the rapid development of modern transportation in the world, the asphalt pavement structure has become one of the most preferred structures of highways due to its advantages for comfortable driving and fast traffic opening [1].
Many methods have been presented in the pursuit of a perfect design for asphalt pavement structure. In the earliest considerations of rutting in road design, the vertical strain on the top of the subgrade was limited to constrain the rutting [5, 6].
Fatigue is one of most important distresses in asphalt pavement structure due to repeated load of heavy traffic services which occur at intermediate and low temperatures as shown in Figure 11.
And, the continuously reinforced concrete and asphalt composite pavement (CRC+AC) is featured by high integral structure strength, superior driving comfort, long service life, and low maintenance cost, which is deemed as the development direction of the long-life asphalt pavement structure of the heavy-load transportation expressway [1-3].
Density requirements in Kansas vary based on location within the asphalt pavement structure and the expected axle loadings.
Using full-scale performance and laboratory tests, the researchers demonstrated that asphalt modified with crumb rubber could significantly slow or stop the growth of fatigue cracks in a composite asphalt pavement structure. A hybrid technique to modify asphalt with a combination of crumb rubber and conventional polymers, called terminally blended crumb rubber, exhibited good fatigue cracking resistance relative to the control binder.
Having analysed the volume and composition of heavy traffic of the test section in 710 m length and 27 different experimental pavement structures, it was determined that the largest destructive impact on asphalt pavement structure is caused by a two-axle truck tractor with three-axle semitrailer and heavy-weight vehicles with three axles and four axles.
