ASTM E2157-15 用圆形轨道计测量路面宏观结构特性的标准试验方法

5.1 In the PIARC International Experiment (1)4 it was found that the volumetric mean texture depth (MTD) was highly correlated to the speed constant of the International Friction Index. It has been found that the average of the MPD values for the eight segments using the CTMeter is extremely highly correlated with the MTD and can replace the volumetric measurement for determination of the MTD (2). The recommended relationship for the estimate of the MTD from the MPD by the CTMeter is: Where MTD and MPD are expressed in millimetres. Note 1: These equations differ from those given in Practice E1845, which are for the estimated texture depths from linear profiles. 5.2 Comparison of the MPD and the RMS for a surface provides information of the nature of the texture, that is, whether the texture is positive or negative (3). 5.3 Analysis of the individual segments can be performed to examine the profile parallel to the direction of travel (Segments A and E) and perpendicular to the direction of travel (Segments C and G). This information could be particularly useful in the study of surfaces that have texture with significant directional characteristics. 1.1 This test method covers the procedure for obtaining and analyzing pavement macrotexture profiles using the Circular Track Meter (CTMeter). 1.2 The CTMeter consists of a charge coupled device (CCD) laser displacement sensor that is mounted on an arm that rotates such that the displacement sensor follows a circular track having a diameter of 284 mm. 1.3 The CTMeter is designed to measure the same circular track that is measured by the Dynamic Friction Tester (DFTester). 1.4 The CTMeter can be used both for laboratory investigations and in the field on actual paved surfaces. 1.5 The software developed for the CTMeter reports the mean profile depth (MPD) and the root mean square (RMS) values of the macrotexture profiles. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health pract......

ASTM D7226-13 采用轮桨式粘度计测定乳化沥青粘度的标准试验方法

5.1 The viscosity of emulsified asphalts characterizes their flow properties and affects their utility at 50°C or at other temperatures. The sprayability and workability of an emulsified asphalt are directly related to its viscosity for many applications. The material must be thin enough to be sprayed yet thick enough such that it will not flow from the crown or grade of the road. For mixing grade emulsified asphalts the viscosity will affect its workability and resulting film thickness on the aggregate. This test method is useful to measure the apparent viscosity of emulsified asphalt at a temperature of 50°C, 25°C, or another agreed-upon temperature. The preset temperature and rotational speed at 100 RPM allow for an automated and consistent determination of an emulsified asphalt viscosity within a short time. 1.1 This test method utilizes the rotational paddle viscometer to measure the viscosity of emulsified asphalt. It is applicable to all the emulsified asphalts described in Specifications D977 and D2397. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7313-13 采用盘状紧凑拉伸几何法测定地沥青集料混合物断裂强度的标准试验方法

4.1 The test method was developed for determining the fracture resistance of asphalt-aggregate mixtures. The fracture resistance can help differentiate mixtures whose service life might be compromised by cracking. The test method is generally valid for specimens that are tested at temperatures of 10°C (50°F) or below (see Note 1). The specimen geometry is readily adapted to 150 mm diameter specimens, such as fabricated from Superpave (trademark) gyratory compactors (Test Method D6925), that are used for the asphalt concrete design process. The specimen geometry can also be adapted for forensic investigations using field cores of pavements where thin lifts are present. This geometry has been found to produce satisfactory results for asphalt mixtures with nominal maximum aggregates size ranging from 4.75 to 19 mm.5Note 1—The stiffness of the asphalt binder tends to influence the assessment of a valid test as described in 7.4. For instance a soft asphalt binder, which may be required for a very cold climate might not lead to a mixture that would produce valid results at 10°C and conversely, a hard asphalt binder utilized in hot climates may require higher temperatures to provide any meaningful information.Note 2—The quality of the results produced by this test method are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this test method are cautioned that compliance with Specification D3666 alone does not completely assure reliable results. Reliable results may depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guidelines provides a means of evaluating and controlling some of those factors. 1.1 This test method covers the determination of fracture energy (Gf) of asphalt-aggregate mixtures using the disk-shaped compact tension geometry. The disk-shaped compact tension geometry is a circular specimen with a single edge notch loaded in tension. The fracture energy can be utilized as a parameter to describe the fracture resistance of asphalt concrete. The fracture energy parameter is particularly useful in the evaluation of mixtures with ductile binders, such as polymer-modified asphalt concrete, and has been shown to discriminate between these materials more broadly than the indirect tensile strength parameter (AASHTO T322, Wagoner2). The test is generally valid at temperatures of 10°C (50°F) and below, or for material and temperature combinations which produce valid material fracture, as outlined in 7.4. 1.2 The specimen geometry and terminology (disk-shaped compact tension, DC(T)) is modeled after Test Method E399 for Plane-Strain Fracture Toughness of Metallic Materials, Appendix A6, with modifications to allow fracture testing of asphalt concrete. 1.3 The test method describes the testing apparatus, instrumentation, specimen fabrication, and analysis procedures required to determine fracture energy of asphalt concrete and similar quasi-brittle materia......

ASTM D6933-13 乳化沥青中尺寸过大颗粒的标准试验方法(过筛试验)

3.1 The retention of an excessive amount of particles on the sieve indicates that problems may occur in handling and application of the material. Particles of asphalt retained on the sieve often are caused by agglomeration of the dispersed phase. Storage, pumping, handling, and temperature can all contribute to the formation of particles. Contamination from the tank, transport, or hose are other factors affecting particle formation. 1.1 This test method covers the degree to which an emulsified asphalt may contain particles of asphalt or other discreet solids retained on a 850-μm mesh sieve. 1.2 The values stated in SI units are to be regarded as standard.
