## 5 Conclusions  
1. This paper investigated the effect of compactness, moisture content, and temperature on the strength growth law variability for cement-stabilized macadam bases. Unconfined compressive and indirect tensile strength tests were used to examine the effects of compactness, moisture

content, and temperature on compressive strength and the splitting strength of specimens at different curing times. The grey relational degree method was used to analyze the variability of each factor on strength variability, and the degree of influence was compactness > water content > temperature.
2. The number of loading vehicles and the number of standard axle loads were calculated during the construction period, which could provide reference for stress analysis of semirigid base courses. The maximum bottom tensile stress under different loads, moduli, and thickness of base courses were calculated using simulation software. The influence law for tensile stress was given, and the determination standard for thickness and elastic modulus was given.
3. Based on the actual project, the influence of different loads and curing time on the maximum tensile stress at the bottom of the stratum was obtained, and the fatigue prediction equation for cement-stabilized macadam with a 50% guarantee rate was obtained via the bending tensile strength and fatigue tests.
4. The fatigue life of the subbase under different construction conditions was calculated by establishing pavement working condition models for different construction periods. Finally, the accumulated life loss of the pavement under different construction loads was obtained using Miner linear cumulative damage theory.
