采用静压成型×h=150 mm×150 mm大粒径沥青混合料(LSAM)试件,通过大量的室内试验,研究分析了公称最大粒径分别为37.5 mm和31.5 mm的LSAM回弹模量、无侧限抗压强度、劈裂抗拉强度的力学指标。试验结果表明,LSAM的抗压回弹模量是普通沥青混凝土的1.3倍左右;LSAM的回弹模量、抗压强度和劈裂抗拉强度分别是半刚性材料的2倍左右。
The LSAM rebound modulus of 37.5 mm and 31.5 mm respectively with the largest nominal particle size was studied through a large number of laboratory tests using static pressure forming × h = 150 mm × 150 mm large particle size asphalt mixture (LSAM) Quantity, unconfined compressive strength, splitting tensile strength of the mechanical indicators. The test results show that the compressive resilience modulus of LSAM is about 1.3 times that of ordinary asphalt concrete. The modulus of elasticity, compressive strength and splitting tensile strength of LSAM are about 2 times that of semi-rigid materials, respectively.
