由恩施州交通局、恩施州公路总段、武汉工业大学共同承担,恩施市公路段协作的科研课题“石屑混凝土路面技术的研究与应用”,经过共同努力,达到了预期研究成果,并于1994年9月5日～6日在恩施市通过专家鉴定。 鉴定会专家们一致认为该课题立题和研究技术路线正确。试验数据可靠。通过用石屑混凝土材料的试验研究,说明石屑混凝土强度比河砂混凝土强度高。室内试验和试验路段及推广路段证明。石屑混凝土在 By the Enshi state Department of Transportation, Enshi state highway section, Wuhan University of Technology common undertaking, Enshi City highway section of scientific research project “research and application of stone chip concrete pavement technology”, through joint efforts to achieve the expected research results, and at September 5, 1994 to 6 in Enshi City, through expert identification. Appraisal experts agreed that the issue of the subject and research technology line is correct. Test data is reliable. Through the experimental research with the stone concrete material, the strength of the stone concrete is higher than that of the river sand concrete. Indoor test and test sections and promotional sections prove. Stone concrete at
