【摘要】 通过几种常用半刚性基层材料的抗压、劈裂、应力－应变全曲线等力学试验，易压实性试验和干湿循环及冻融循环等耐久性试验，并结合材料在实体路面工程中的使用效果，综合评价了这些材料的路用性能，提出了在南方地区选用半刚性基层材料的建议性意见．更多还原

【Abstract】 In this paper, the author comprehensively evaluates the performance of several kinds of semi-rigid base materials and puts forward proposals about the selection of the materialsused in highway construction in South China by using the data gained form mechanics experiments of the materials, including compressive resistance, split test, stress -strain whole curvetest,compactability test and durability experiments including drying- moisturizing cycle,freezing-melting cycle , etc, and by combining the test date with the engineering effect of thematerials used in highway entity pavements.更多还原
