ASTM D7228-06a 预测地沥青路面铺层温度的标准试验方法

Analysis of deflection data from asphalt pavements almost always requires that the raw deflections or the analysis results from the load-deflection data be adjusted for the effects of pavement surface course temperature. Measuring the temperature at-depth normally requires that a hole be drilled into the pavement, partially filled with fluid, and the temperature measured with a hand-held device. Alternatively, thermistors or other temperature instrumentation may be permanently installed at various locations. Current deflection testing equipment is often equipped with surface temperature sensing devices, for example an infrared thermometer that measures the surface temperature at every test location. To adequately adjust the deflection or deflection results for the effects of temperature, the temperature at some depth must be known. This test method provides a means of estimating the temperature at-depth from the pavement surface temperature, the time of day, the previous day’s high and low air temperatures, and the desired depth where the temperature is to be estimated. Utilization of this method results in a significant savings in time over the conventional practice of manually drilling holes into the pavement, and it results in a significant increase in the volume of temperature data (one pavement temperature for each test point) and the ability to record temperature variations between test points.1.1 This test method covers a means of predicting temperatures within the asphalt-bound layer(s) of a flexible pavement section.1.2 Deflection testing commonly involves the measurement of pavement surface temperatures. This standard is based on temperature relationships developed as part of the Federal Highway Administration (FHWA) Long Term Pavement Performance (LTPP) Seasonal Monitoring Program.

ASTM E2340-06 用连续读数固定防滑技术对道路和其他区域表面防滑测试的标准试验方法

CFMEs are used to measure skid resistance on runways, roads, and various other trafficked surfaces. These tests may comprise operational testing, performed to obtain an immediate assessment of skid resistance in current conditions or routine testing in standardized conditions which include the application of a precise amount of water in front of the test tire. Standard test speeds and nominal water film thicknesses are according to national or international agency standards, the type of CFME, and the test application. Some examples of typical applications are given in Appendix X1.1.1 This test method covers the measurement of the skid resistance of a pavement or other trafficked surface using the continuous reading, fixed-slip technique.1.2 This test method covers braked wheel measurements obtained with less than 100 % slip. It does not cover side force measurements.1.3 This test method provides a record of the skid resistance along the whole length of one track of the test surface and enables averages to be obtained for specified test segments.1.4 This test method is used to measure skid resistance on a wide variety of surfaces in a wide variety of circumstances. Consequently, there are many different designs of continuous reading, fixed-slip measuring equipment (CFME) and as many different test procedures governing their use.1.5 This test method does not attempt to detail these different equipments and procedures but does set out the essential common principles.1.6 CFMEs function by creating and measuring a frictional force between a test tire operating at a selected slip and the test surface. Different types of CFME do not necessarily create the same frictional force between their particular test tire and a common test surface and do not necessarily use the same method to measure this frictional force.1.7 CFME measurements are obtained at a selected steady test speed. This speed may vary according to the application.1.8 The test surface may be contaminated or clean and dry. If it is clean and dry, a measured amount of water is normally deposited on the surface just in front of the test wheel.1.9 The measuring apparatus may be built into a vehicle, built into a trailer that is towed by a vehicle, or built into a device that is manually pushed.1.10 The values stated in SI units are to be regarded as the standard.

ASTM D7115-05 用模拟载荷测量精密铺砌旋转压实机(SGC)的回旋内角的标准试验方法

SGCs are used to produce hot-mix asphalt (HMA) specimens in the laboratory to assess volumetric properties and predict pavement performance. In the fabrication of an SGC specimen in accordance with Test Method D 6925, loose HMA is placed inside a metal mold, which is then placed into an SGC. A constant consolidation pressure is applied to the sample while the mold gyrates at a nominally constant angle (referred to as the angle of gyration) and rate. Consistency in the density of the asphalt specimens produced as measured by Test Method D 2726 or D 6752 is very important to the validity of the tests performed. Specimens of a consistent density are produced when an SGC maintains a constant pressure and a known constant angle of gyration during the compaction process. There are several manufacturers and models of SGC. Each model employs a unique method of setting, inducing, and maintaining the angle of gyration. Each model also employs a unique calibration system to measure the external angle of gyration. These existing calibration systems can not be used universally on all of the different SGC models commercially available. Inconsistencies in asphalt specimens produced on different SGC models have been at least partially attributed to variations in the angle of gyration. This method describes instruments and processes that can be used to independently measure the internal angle of gyration of any manufacturers’ SGC model under simulated loading conditions. The external shape of the instrument chassis assures that the points of physical contact between the mold end plates and the instrument occur at a fixed and known distance away from the axis of gyration. As a result, the vertical load is applied at these fixed points, creating tilting moments at each end of the mold. Unless otherwise specified, tilting moments corresponding to an eccentricity of 22 mm shall be used to simulate the loading conditions of a standard SGC volumetric specimen.1.1 This test method covers the procedure for the measurement of the Superpave Gyratory Compactor (SGC) internal angle of gyration using an instrument capable of simulating loading conditions similar to those created by a hot mix asphalt specimen.This standard does not purport to address all of the safety concerns, if any, associated with its use.
