    Improving Concrete Durability by Using Optimized Aggregate Gradation and Reducing Cement Content حسب Chung, Hung-Wen

    منشور في 2020
    "…The main findings from this study are as follows: (1) The cementitious content of typical Florida pavement and structural concrete can be reduced by as much as 10 to 15% without loss in workability of the fresh concrete, and without decreasing the strength and durability of the hardened concrete. (2) Portlandlimestone cement (Type IL) can be used as a substitute for ordinary Portland cement (Type I/II). (3) The OAG technique can be used to efficiently reduce the cementitious content of the concrete mixes and to improve their performance."…"

    Concrete Pavement Truck Equivalence Factors For Upgrades حسب Razouki, Sabah Said

    منشور في 1999
    "…Presented in this paper are the upgrade truck equivalence factors for single unit trucks of type, 1.2 and 1.22 which are not covered by AASHTO. The equivalency factors for front and rear axles of single unit trucks were developed using AASHO Road Test equation after considering the decrease in front axle load and the increase in rear axle load due to the axle load redistribution on upgrades. …"
