By controlling the range of the dry density , magnitude of cement and water cement ratio of mixture , the requirement of drainage property and structure strength can be fulfilled 通過控制混合料的干密度、水泥用量和水灰比的取值范圍,可使混合料同時滿足排水性能要求和結(jié)構(gòu)強度要求。
Different from marshall method , gtm can imitate the actual situation of the interaction between wheel and ground , and in response to stress , it can make its density to attain the actual function of wheeling on the road , and we can design the suensity and ratio of mixture 與馬歇爾實驗的方法不同,它可以最大限度地模擬車輪同地面相互作用的實際情形,根據(jù)接觸應(yīng)力的大小,通過旋轉(zhuǎn)壓實試件,使其密度達到車輪實際作用于路面時產(chǎn)生的最大密實度,來設(shè)計合乎要求的瀝青混凝土路面的密實度及混合料的配合比。
