摘要: <正>结合多年的施工经验,从材料选用、配合比设计、铺筑方法等方面分析二灰碎石基层施工中的质量控制措施。结果表明:在摊铺作业时,应保持作业的连续性;在气温较高时施工,应保证碾压时二灰碎石的含水量,并快速摊铺、碾压;施工完毕要保湿养生7d,气温较低时还需采取覆盖措施,防止表面冻坏。

Abstract: By means of spot survey in Fuqing, Fujian Province from 2003 to 2004, the results showed that the initial and important stage of Hemiberlesia pitysophila spreading to spring tips from autumn tips of pine was Sept. and Oct., and the stage of the pests spreading from spring tips to autumn tips was March, April and May. The pests began spreading to spring tips in the middle ten-day of Sept., and the last ten-day of Oct. was the fastigium. Moreover, the pests began spreading to autumn tips in the last ten-day of April, and the first and last ten-day of May was the fastigium. In the period from Sept. to Dec., number of the pest population on the old tips declined tardily, but that on the new tips increased rapidly. As a whole, number of the pest population on the new tips reached the level of the old tips by 105 days development after the first time of the new tips attacked by the pest.
