随着我国石油工业的发展,沥青产量日益增加。目前各有关单位正在进行采用国产沥青铺筑路面的研究工作。为了适应群众性的研究活动,就需要有简单、实用的仪器。本文所介绍的就是沥青混凝土试验制备试件时用的两种仪器——成型机与脱模机。室内试验用的沥青混凝土试件是一圆柱形。它是在一定尺寸的圆筒状钢模中,放入一定重量的沥青混凝土混合料,在钢模的两端各塞一圆柱形压头(图1),再拿到压力机上加一定压力,然后将试件顶出即成。因此,在成型时必须要有压力机。但一般基层单位还没有压力机设备,这就给试验造成一定困难。我们在
With the development of China’s oil industry, asphalt production is increasing. At present, all relevant units are carrying out research work using domestic asphalt pavement. In order to adapt to mass research activities, there is a need for simple and practical instruments. This article describes two samples of asphalt concrete specimens used in the preparation of test equipment - forming machine and stripping machine. The asphalt concrete specimen for indoor test is cylindrical. It is a certain size of the cylindrical steel mold, put a certain weight of asphalt mixture at both ends of the steel mold plug a cylindrical pressure head (Figure 1), and then get the press plus a certain pressure, Then the specimen top Serve. Therefore, the molding machine must have a press. However, the general grass-roots units have not yet press equipment, which gave the test a certain degree of difficulty. we are at
