为了检测沥青混凝土路面层间黏结强度及桥面防水层黏结强度,开发了可用于现场和室内试验用的拉拔仪和剪切仪。用该仪器对某城际快速干线在修筑过程中进行了106个试样的现场试验,不仅得到了该快速干线沥青混凝土路面层间黏结强度及桥面防水层黏结强度的分布规律,而且对施工质量起到了监控作用。研究成果可为其他沥青混凝土路面和桥面施工质量控制提供参考。
In order to detect the inter-layer bonding strength of asphalt pavement and the waterproof strength of the bridge deck, a drawing device and a shear device for field and laboratory tests were developed. With this instrument, a field test of 106 samples during the construction of an inter-city rapid trunk line was carried out. Not only the distribution law between the inter-layer bond strength of the expressway asphalt concrete pavement and the bond strength of the bridge deck waterproofing layer was obtained, Quality has played a monitoring role. The research results can provide references for other asphalt concrete pavement and bridge deck construction quality control.
